3,000 Immortelle Oil Bubbles

Golden micro-capsules preserve 100% organic Immortelle essential oil at peak potency. The bubbles burst upon contact with skin, releasing the antioxidant-rich oil for maximum efficacy.

Overnight Skin Reset Technology

Formulated to synchronise with the skin's natural nocturnal repair cycle. Acmella Oleracea extract visibly relaxes expression lines while Adenosine supports cellular-level renewal.

Multi-Level Hydration

Combines humectants (Glycerin ~4%, Propanediol, Butylene Glycol, Pentylene Glycol) to attract moisture and emollients (Meadowfoam Seed Oil, Isononyl Isononanoate) to lock it in all night long.

Marjoram Leaf Extract — Gene-Activation

Origanum Majorana Leaf Extract has been shown to help reactivate gene expression functions that slow with age and environmental stress, supporting the skin's intrinsic regenerative ability.

Refill-Ready & Eco-Conscious

The glass bottle is designed to be refilled, reducing packaging waste. L'Occitane sources Immortelle from Corsica using responsible, sustainable harvesting practices.

Visible Radiance from Night One

In a clinical study of 31 women tested after a single night, 97% reported looking more rested and fresh, and 81% observed visibly more radiant skin the following morning.

Safety & compatibility

SAFE
Pregnancy & Breastfeeding

Generally considered low-risk as it contains no retinoids, salicylic acid, or hydroquinone. However, it does contain Parfum (fragrance) and Helichrysum Italicum essential oil, which some pregnancy guidance advises limiting. Consult your healthcare provider before use during pregnancy or breastfeeding.

Fungal Acne (Malassezia)

Use with caution if you are prone to fungal acne (Malassezia folliculitis). The formula contains Isononyl Isononanoate and Palmitic Acid, fatty acid esters that may feed Malassezia. Patch test recommended for those with active fungal acne.

Retinol Compatible

Contains no actives that conflict with retinol. The hydrating and soothing ingredients (Glycerin, Adenosine, Meadowfoam Oil) can help buffer any dryness from retinol use. Apply this serum first, then retinol on top, or on alternating nights.

Vitamin C Compatible

No conflicts with L-Ascorbic Acid or derivative Vitamin C serums. The antioxidant Tocopherol (Vitamin E) in this formula actually works synergistically with Vitamin C, boosting its stability and efficacy.

AHA / BHA Compatible

No inherent conflicts with AHAs (glycolic, lactic acid) or BHAs (salicylic acid). The emollient, barrier-supporting ingredients can help reduce post-exfoliant sensitivity. Apply exfoliating acids first, allow full absorption, then apply this serum.

Low Comedogenic Risk

Rated 1/5 overall. Key oils are Meadowfoam Seed Oil (comedogenic rating 1) and Sunflower Seed Oil (rating 0–2). The formula is lightweight and gel-based with fast absorption, making it unlikely to clog pores for most skin types.

Fragrance Present

This product contains Parfum (fragrance), which may cause irritation or allergic reactions in individuals with very sensitive or reactive skin. Perform a patch test on the inner forearm for 24–48 hours before full facial application.

Paraben-Free & Sulfate-Free

Free of parabens, SLS, and SLES. Preservation is achieved via Phenoxyethanol, a widely accepted cosmetic preservative, and the natural antimicrobial properties of Pentylene Glycol.

Ingredient breakdown

INGREDIENTS

Helichrysum Italicum Flower Oil (Immortelle Essential Oil) ~0.5–1%Proven

The hero ingredient of this formula — 100% organic Immortelle (Everlasting) essential oil sourced from Corsica. Encapsulated in 3,000 golden micro-bubbles to preserve its potency until the moment of application. Rich in italidiones (diketones), flavonoids, and terpenoids, it delivers powerful antioxidant defence, helps stimulate micro-circulation, and supports collagen production for visible anti-ageing results.

  • Antioxidant Action: Italidiones in Immortelle oil neutralise free radicals generated by UV, pollution, and metabolic stress.
  • Micro-circulation: Clinical research associated with L'Occitane's Immortelle extract has shown potential to double micro-circulation rate in skin, aiding cell renewal.
  • Anti-inflammatory: Flavonoids in Helichrysum have demonstrated anti-inflammatory activity in published studies.
Sourced from certified-organic cultivation in Corsica, France. Concentrated to 10x higher levels in the latest formula versus the original 2018 launch.

Adenosine ~0.35–0.75%Proven

A naturally occurring purine nucleoside involved in cellular energy transfer and signalling. As a topical skincare ingredient, Adenosine is one of the most clinically validated anti-wrinkle actives available, with a strong safety profile and no photosensitivity concerns — making it ideal for both day and night use.

  • Clinical Evidence: A high-quality randomised controlled trial demonstrated topical Adenosine significantly improved deep dynamic wrinkles (forehead, crow's feet) versus placebo over 12 weeks.
  • Mechanism: Stimulates fibroblast activity and promotes synthesis of extracellular matrix proteins including collagen and fibronectin.
  • Safety: No photosensitivity, no known drug interactions when applied topically. Suitable for all skin types including sensitive.
Estimated concentration 0.35–0.75% based on WIMJ formulation analysis — sufficient range per clinical evidence for wrinkle-smoothing benefit.

Acmella Oleracea Extract (Spilanthes / Toothache Plant) ~0.1–0.5%Proven

A powerful botanical active derived from the Spilanthes acmella flower, traditionally used in Ayurvedic medicine. The key active compound, Spilanthol, is an N-alkylamide with documented muscle-relaxing properties that help visibly smooth expression lines, particularly around the eyes and forehead, without paralysing muscle tissue.

  • Mechanism: Spilanthol interferes with sodium channel activity in superficial facial muscles, temporarily reducing micro-contractions that form expression lines.
  • Published Research: Studies demonstrate visible reduction in periocular wrinkle depth with regular topical application of Acmella extract over 28 days.
  • L'Occitane Claim: Described as providing "immediate smoothing" properties within the Immortelle range.

Limnanthes Alba (Meadowfoam) Seed Oil ~2–4%Proven

A highly stable, non-greasy emollient oil pressed from Meadowfoam seeds. Its fatty acid profile (~95% long-chain C20–C22 fatty acids) is remarkably unique and gives it exceptional oxidative stability — it resists rancidity far longer than most plant oils. Comedogenic rating of 1 makes it suitable for most skin types.

  • Emollient: Softens and smooths the skin surface, reduces trans-epidermal water loss (TEWL), and enhances barrier function.
  • Stability: Unlike many oils, Meadowfoam Oil does not degrade under oxidative stress, making it ideal in formulations with antioxidant actives.
  • Comedogenic Rating: 1/5 — very low pore-clogging potential.

Glycerin ~3.4–5.1%Proven

One of the most well-researched and effective humectants in cosmetics. Glycerin is naturally found in the skin and works by drawing water from both the environment and deeper skin layers up to the stratum corneum, maintaining optimal hydration levels throughout the night.

  • Concentration (WIMJ estimate): 3.4–5.1% — an effective humectant dose that delivers meaningful hydration improvement.
  • Skin Barrier: Studies confirm Glycerin supports lamellar body secretion and contributes to a healthy, intact skin barrier.
  • Penetration: Able to reach the stratum granulosum layer, providing genuine deep-layer moisture retention.

Origanum Majorana Leaf Extract (Marjoram) ~0.1–0.3%Promising

Sweet Marjoram leaf extract, one of the lesser-known actives in this formula. Contains phenolic compounds, flavonoids, and terpenoids. Research has highlighted its potential to re-activate gene expression pathways that become less efficient due to aging and cumulative exposure to UV radiation, pollution, and stress.

  • Gene Expression: Preliminary research indicates Marjoram extract may help upregulate skin renewal genes suppressed by external aggressors (UV, pollution, oxidative stress).
  • Antioxidant: High in rosmarinic acid and other polyphenols that neutralise free radicals.
  • Soothing: Mild anti-inflammatory properties reported in in-vitro studies.

Tocopherol (Vitamin E) ~0.1–0.5%Proven

Pure, unesterified Vitamin E — the most bioavailable form for topical application. Acts as both a potent lipophilic antioxidant and a secondary emollient. Works synergistically with Vitamin C serums used in your broader routine and helps stabilise the Immortelle essential oil from oxidative degradation.

  • Antioxidant: Neutralises lipid peroxidation chain reactions in cell membranes, protecting skin from UV- and pollution-induced free radical damage.
  • Synergy: Vitamin E regenerates photo-oxidised Vitamin C, amplifying the efficacy of any Vitamin C product used in combination.

How to use

HOW TO USE
1

Cleanse & Tone

Start with a gentle cleanser to remove makeup, SPF, and daily pollutants. Follow with your regular toner or essence to balance skin pH and prep the complexion for maximum serum absorption.

2

Pump & Observe the Bubbles

Dispense 1–2 pumps of serum onto fingertips. You'll see the beautiful golden oil bubbles suspended in the gel. The recommended amount is 1 pump, though many users with drier or larger skin prefer 2 pumps for full face and neck coverage.

3

Apply with Gentle Massage

Dot the serum across cheeks, forehead, chin, and neck. Use upward, outward circular massage motions to burst the golden oil capsules and blend evenly. Focus extra product on areas where fine lines are most visible (crow's feet, forehead, nasolabial folds).

4

Allow Absorption

Wait 30–60 seconds for the serum to fully absorb. The lightweight, fast-sinking formula should leave no residue or tackiness — just a slightly dewy, supple skin feel.

5

Seal with Moisturiser

Apply your regular night moisturiser or sleeping mask over the serum to lock in hydration. L'Occitane recommends Immortelle Divine Cream, but any compatible night cream works well as a final occlusive layer.

06

Who is it for?

WHO

Perfect for you if:

  • You have mature or aging skin showing fine lines and loss of radiance
  • Your skin looks dull, tired, or stressed after long days
  • You want a lightweight serum that doesn't feel heavy or greasy overnight
  • You prefer natural-origin, luxe formulations over heavily synthetic serums
  • You're looking for a French pharmacy–quality anti-aging nighttime serum
  • You have normal, dry, combination, or sensitive skin
  • You want a single serum that addresses hydration, glow, and fine lines

Consider alternatives if:

  • You need a high-potency active (retinol, niacinamide, peptides) as your primary anti-aging treatment
  • You have fragrance-sensitive or highly reactive skin (product contains Parfum)
  • You have active fungal acne — some esters in the formula may aggravate Malassezia
  • You are on a tight budget — a 30ml bottle at $64 USD offers limited cost-per-use value
  • You need a product for daytime use without SPF — this is formulated for night
  • You want dramatic, clinically-proven wrinkle reduction equivalent to prescription actives
07

Skin type compatibility

SKIN TYPES
Normal Skin
Excellent

Ideal candidate. The balanced oil-in-gel formula provides just the right level of hydration and antioxidant protection without being excessive or insufficient.

Dry Skin
Good

Good hydration boost from glycerin and meadowfoam oil. Best results when layered under a richer night moisturiser or sleeping mask to prevent overnight moisture loss.

Combination Skin
Excellent

The lightweight, fast-absorbing oil-in-gel texture is perfectly suited to combination skin — hydrates dry areas without congesting the T-zone.

Oily Skin
Good

The gel base absorbs quickly without leaving a shiny or heavy residue. Low comedogenic rating (1/5) makes it unlikely to trigger breakouts. 1 pump is usually sufficient.

Sensitive Skin
Good

L'Occitane markets this as suitable for sensitive skin. No parabens, no SLS. However, Parfum is present — patch test strongly recommended for very reactive skin types.

Acne-Prone Skin
Moderate

Low overall comedogenic rating but Isononyl Isononanoate and Palmitic Acid may be problematic for Malassezia-prone or highly acne-prone individuals. Patch test advised.

Budget-friendly alternatives (dupes)

DUPES
72% Match
Advanced Snail 96 Mucin Power Essence
$25.00
Budget Pick

Both are lightweight serums delivering deep hydration and a plump, rested morning skin. COSRX uses Snail Secretion Filtrate instead of Immortelle oil as the hero ingredient — excellent for barrier repair, skin renewal, and hydration, but lacks the distinctive Helichrysum antioxidant profile and does not contain Adenosine or Acmella Oleracea. Less luxurious sensory experience; K-beauty formula. Fragrance-free.

68% Match
Natural Moisturizing Factors + HA
$10.90
Budget Pick

Covers the humectant and barrier-support aspects of the L'Occitane serum at a fraction of the cost. Contains multiple forms of hyaluronic acid, amino acids, and ceramide precursors. Lacks the Immortelle antioxidant complex, Adenosine, Acmella Oleracea, and plant oil emollients. Not an oil-in-serum format; more of a standard hydrating serum. Fragrance-free and fungal-acne safe.

65% Match
Luna Retinol Sleeping Night Oil
$55.00
Similar Price

A similarly positioned overnight facial oil-serum with antioxidant-rich botanicals (Blue Tansy, German Chamomile, Retinol). Closer in price and luxury positioning to the L'Occitane serum. Key difference: Sunday Riley Luna contains retinol — making it more potent for wrinkle correction but less suitable during pregnancy and for retinol-sensitive skin. More likely to cause initial purging. The L'Occitane serum is gentler, without the risk of retinol side effects.

Storage & shelf life

12 MONTHS
Period After Opening (PAO)

12 months after opening. Look for the open-jar symbol on the packaging showing "12M." Discard if the product changes colour, texture, or smell significantly before this date.

Storage

Store in a cool, dry place away from direct sunlight and heat. The Immortelle essential oil's antioxidant properties make the formula relatively stable, but excess heat and UV light can degrade the botanical actives over time. Avoid storing in a steamy bathroom.

Packaging

Luxe glass bottle with a pump dispenser. The glass construction protects the formula from light degradation. Designed to be refill-ready — L'Occitane offers dedicated refill pouches for sustainability. Available in 30ml and 50ml sizes.

Travel Friendly

The 30ml size qualifies for carry-on liquids (under 100ml limit). However, the glass bottle is fragile — pack carefully in a padded bag. The pump should be locked during travel to prevent accidental dispensing.

Frequently asked questions

FAQ

This serum does not contain retinoids, hydroquinone, or salicylic acid — the most commonly flagged ingredients to avoid during pregnancy. However, it does contain Helichrysum Italicum essential oil and Parfum (fragrance), and some essential oils are recommended to be used cautiously during pregnancy, particularly in the first trimester. While the levels present in a cosmetic serum are likely low, we always recommend consulting your midwife, OB-GYN, or dermatologist before using any new skincare product during pregnancy or while breastfeeding. Your healthcare provider can give you personalised guidance based on your individual circumstances.

Use with caution if you are prone to fungal acne (Malassezia folliculitis). The formula contains Isononyl Isononanoate, a fatty acid ester, and Palmitic Acid — both of which can potentially feed Malassezia yeast. Additionally, Limnanthes Alba (Meadowfoam) Seed Oil and Helianthus Annuus (Sunflower) Seed Oil are present, which are relatively low-risk plant oils but still technically fatty acids that Malassezia can metabolise. If you have active fungal acne, it is advisable to patch test on a small area and monitor for 1–2 weeks before full application, or to consult a dermatologist for a fungal-acne safe alternative.

Yes, this serum is compatible with all three. With retinol: the hydrating and soothing ingredients in this serum (Glycerin, Meadowfoam Oil, Adenosine) can help buffer irritation from retinol — apply this serum first, allow full absorption, then apply retinol. Alternatively, use them on alternating nights. With Vitamin C: there are no conflicting interactions. Tocopherol (Vitamin E) in this serum actually works synergistically with Vitamin C, enhancing its stability. Use Vitamin C in the morning and this serum at night. With AHAs (glycolic, lactic) and BHAs (salicylic): apply your acid treatment first, wait for full absorption, then layer this serum on top. The emollient, barrier-supportive ingredients can actually help reduce post-exfoliation sensitivity.

This serum works best for normal, dry, combination, and sensitive skin types. The lightweight oil-in-gel texture is versatile enough for combination and oily skin (rated excellent for combination skin), while the emollient oils and hydrating humectants provide sufficient nourishment for normal to dry skin. Sensitive skin types can generally tolerate it well as it is free from parabens and sulfates, though the Parfum (fragrance) component means a patch test is recommended. Oily skin types will likely find 1 pump more than sufficient. Those with active fungal acne or highly congested acne-prone skin should patch test first due to the ester and fatty acid content.

Many users notice a difference from the very first morning — waking up with visibly plumper, more rested-looking skin thanks to the fast-acting humectants and Acmella Oleracea extract. In a clinical test on 31 women after a single night of use, 97% reported looking more rested and fresh, and 81% had visibly more radiant skin. For deeper fine line reduction and longer-lasting anti-aging benefits from Adenosine and Immortelle Essential Oil, expect to see meaningful improvement after 4 weeks of consistent nightly use. Maximum cumulative results typically appear after 8–12 weeks. Consistency is key — using the serum every night delivers the best outcomes.

This is an evening serum applied as step 4 in a night routine: (1) Cleanser → (2) Toner / Essence → (3) Optional Triphase Essence → (4) This Serum → (5) Night Moisturiser. As a serum, it goes after any water-based toners or essences but before heavier creams, oils, or sleeping masks. L'Occitane recommends using it after the Immortelle Reset Triphase Essence and before the Immortelle Divine Cream for the full Immortelle system routine. Do not use as a daytime serum without SPF on top, as the botanical oils in the formula may increase photosensitivity without sun protection.

The overall comedogenic rating for this product is estimated at 1 out of 5 — very low. The key oils present are Limnanthes Alba (Meadowfoam) Seed Oil (comedogenic rating: 1) and Helianthus Annuus (Sunflower) Seed Oil (rating: 0–2). The water-based gel carrier with lightweight humectants further reduces any pore-clogging risk. The formula is unlikely to clog pores for the vast majority of users. However, Isononyl Isononanoate (an ester) and Palmitic Acid could potentially be problematic for individuals with Malassezia folliculitis or highly congested acne-prone skin specifically — these are distinct from classical comedogenicity but worth noting for reactive skin types.

The Period After Opening (PAO) for this product is 12 months, indicated by the open-jar symbol on the packaging. With 1 pump per use nightly, the 30ml bottle typically lasts 2–3 months (approximately 60–90 applications), and the 50ml bottle 3–5 months, making both sizes well within the 12-month PAO window for most users. Store in a cool, dry location away from direct sunlight, and always close the pump securely after use to prevent oxidation and contamination. If the texture, colour, or scent changes noticeably before the 12-month mark, discontinue use.

— Skincarisma verdict
4.3 / 5 ★★★★☆

Verdict: The L'Occitane Immortelle Reset Overnight Oil-In Serum is a genuinely luxurious, sensory-forward nighttime treatment that delivers on its core promise of waking up with more rested, hydrated, and radiant skin. Its unique oil-in-gel format with 3,000 Immortelle essential oil bubbles is not a gimmick — the encapsulation preserves the antioxidant-rich oil at peak potency for delivery at point of use. Clinically-validated Adenosine and Acmella Oleracea bring real, evidence-backed wrinkle-smoothing and fine line reduction benefits. The 92% natural-origin, vegan, refill-ready formula reflects L'Occitane's commitment to both efficacy and sustainability. The primary caveats are its premium price point, the presence of Parfum, and the fact that it is more of a maintenance and prevention serum than a potent corrective treatment for advanced skin aging. For those seeking a French beauty overnight serum that combines genuine hydration, antioxidant protection, and visible morning glow — with a pleasurable, spa-like ritual — this is one of the best in class.

lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
