Yuzu Vitamin C Boost

Yuzu citrus contains roughly 3x more vitamin C than a standard lemon, helping to brighten dullness and fight environmental free radicals overnight.

πŸŒ™

Works While You Sleep

The jelly formula seals in actives as the final PM step, so retinol, niacinamide and peptides can act during your skin's natural overnight repair window.

✨

Glass-Skin Glow

Niacinamide and ascorbic acid work together to refine pores, even out tone and deliver a smoother, brighter complexion by morning.

πŸ›‘οΈ

Barrier Support

Ceramide NP, cholesterol and linoleic acid mimic skin's natural lipids to reinforce the moisture barrier β€” useful when layering retinol or vitamin C.

🧬

Multi-Peptide Complex

Six sh-peptides (oligopeptide-1, polypeptide-1, -22, -45, -8, -9) signal to skin to support firmness and renewal as part of the overnight treatment.

🌿

Vegan & Cruelty-Free

Formulated without parabens, sulfates, phthalates, synthetic fragrance or color, and never tested on animals β€” Soko Glam Best of K-Beauty winner.

πŸ›‘οΈ Safety & Compatibility

🀰
Not Pregnancy / Breastfeeding Safe

Contains retinol (vitamin A), which dermatologists generally advise avoiding during pregnancy and breastfeeding. Choose a retinol-free alternative during this time.

🦠
Not Fungal Acne Safe

Contains caprylic/capric triglyceride, polysorbate 20, hydrogenated lecithin and fatty acids that may feed Malassezia yeast. Skip if you struggle with fungal acne.

β˜€οΈ
Use Sunscreen Daily

Both retinol and ascorbic acid increase sun sensitivity. Always apply a broad-spectrum SPF 30+ each morning while using this mask.

βš—οΈ
Patch Test Recommended

Active blend of vitamin C, retinol and niacinamide can cause irritation in sensitive or reactive skin. Test on the inner forearm for 24 hours before full-face use.

βœ…
Non-Comedogenic Rating: 2/5

The base formula is mostly low-comedogenic, though caprylic/capric triglyceride and behenyl alcohol may clog pores in very acne-prone skin types.

🌿
Vegan & Cruelty-Free

Formulated without animal-derived ingredients and never tested on animals. Suitable for plant-based skincare routines.

πŸ”¬ Ingredient Breakdown

🍊 Yuzu (Citrus Junos) Complex ~1–3% Promising

The hero ingredient β€” appears as Citrus Junos peel oil, seed oil and fruit oil. A Japanese-Korean citrus naturally rich in vitamin C, bioflavonoids and limonene. Provides antioxidant defense and the signature zesty scent.

  • Source: Yuzu peel contains roughly 3x more ascorbic acid than common lemons (Korean Journal of Food Science).
  • Benefit: Bioflavonoids may help stabilize vitamin C and amplify its antioxidant activity.
⚠️
Citrus peel oils can be photosensitizing β€” daytime SPF is essential.

πŸ’Ž Niacinamide ~3–5% Proven

Listed as the third ingredient, suggesting an effective concentration. Niacinamide (vitamin B3) is one of the most-studied actives for visibly minimizing pores, evening out tone and reinforcing the moisture barrier.

  • Source: Multiple peer-reviewed studies show 4–5% niacinamide reduces hyperpigmentation and improves barrier lipids.
  • Benefit: Pairs well with retinol β€” actually helps offset retinol-induced redness and dryness.

πŸ‹ Ascorbic Acid (Vitamin C) <1% Proven

Pure L-ascorbic acid β€” the gold-standard form of vitamin C β€” appears mid-list in a low but supportive dose alongside the natural vitamin C from yuzu. Targets dullness and uneven tone.

  • Source: Clinical research shows ascorbic acid inhibits tyrosinase activity, reducing dark-spot formation.
  • Benefit: Stabilized by ferulic-like bioflavonoids and tocopherol in the formula.
⚠️
Vitamin C oxidizes with light and air β€” store the jar tightly closed and away from direct sunlight.

🧬 Retinol <0.1% Proven

A low, beginner-friendly dose of pure retinol (vitamin A). Helps soften the look of fine lines, refine texture and support cell turnover overnight without the irritation of prescription strengths.

  • Source: Retinol is well-documented to stimulate collagen synthesis and accelerate desquamation.
  • Benefit: Buffered by ceramides, peptides and niacinamide to reduce sensitivity.
⚠️
Avoid during pregnancy or breastfeeding. Introduce slowly (2–3 nights/week) if new to retinoids.

🧱 Ceramide NP + Cholesterol + Linoleic Acid ~1% Proven

The classic barrier-repair trio that mimics the lipid composition of healthy skin. Helps lock in hydration overnight and offsets potential dryness from retinol and vitamin C.

  • Source: Optimal ratios of ceramide, cholesterol and free fatty acids accelerate skin barrier recovery (Journal of Investigative Dermatology).

πŸ§ͺ Multi-Peptide Complex <0.5% Promising

Six bioengineered sh-peptides: sh-Oligopeptide-1, sh-Polypeptide-1, sh-Oligopeptide-2, sh-Polypeptide-22, sh-Polypeptide-45, sh-Polypeptide-8 and sh-Polypeptide-9. These signal peptides aim to support firmness, renewal and overall skin quality.

  • Source: Signal peptides are studied for their role in modulating fibroblast activity and collagen production.
  • Benefit: Concentrations are low, so think of these as a supportive booster rather than the main act.

πŸ’§ Glycerin ~10% Proven

Second on the INCI list β€” a powerhouse humectant that pulls moisture from the air and deeper skin layers into the upper epidermis. Key to the mask's plumping, dewy finish.

  • Source: Glycerin is widely cited as one of the most effective and well-tolerated humectants in skincare.

🌿 Sea Buckthorn (Hippophae Rhamnoides) Oil ~0.5% Promising

A nutrient-dense oil rich in omega-7 (palmitoleic acid), beta-carotene, vitamin E and tocopherols. Supports antioxidant defense and gives the mask its faint orange tint.

  • Source: Sea buckthorn has a unique fatty-acid profile and is studied for its skin-soothing and antioxidant properties.

Serum

Moisturizer

Sleep Mask

Use as the very last step of your PM routine, 3–5 nights per week. Skip your night cream if you prefer a lighter feel β€” the mask doubles as a moisturizer for many users.

πŸ“ How to Use

1

Complete your PM routine

Cleanse, tone and apply your usual serum and moisturizer first. The sleep mask works as the sealing final step.

2

Scoop with the spatula

Use the included spatula to take a pea-sized amount. Start small β€” a little goes a long way thanks to the jelly texture.

3

Apply a thin, even layer

Smooth over face and neck, avoiding the eye and lip area. The flecks of yuzu fully dissolve as you press the product into skin.

4

Let it set, then sleep

Allow 3–5 minutes to absorb before lying down so it doesn't transfer to your pillowcase.

5

Rinse in the morning

Wash off with a gentle cleanser and follow with sunscreen. Use 3–5 nights a week β€” start with 2 nights if you're new to retinol.

πŸ‘€ Who Is It For?

βœ… Perfect for you if:

  • You want a multi-tasking overnight treatment with brightening + anti-aging actives
  • Your skin looks dull, tired or uneven and needs a glow boost
  • You're a retinol beginner looking for a low, well-buffered dose
  • You love a luxurious citrus scent and a dewy "glazed" finish
  • You enjoy K-beauty layering and want a final sealing step

❌ Consider alternatives if:

  • You're pregnant or breastfeeding (contains retinol)
  • You struggle with fungal acne / Malassezia folliculitis
  • You're very sensitive to fragrant citrus oils or essential oils
  • You already use prescription tretinoin and want stronger results
  • You dislike a slightly tacky, sticky finish during application

❓ Frequently Asked Questions

No β€” this mask contains retinol (vitamin A), which dermatologists generally recommend avoiding during pregnancy and breastfeeding due to a theoretical risk of fetal harm with topical retinoids. It also contains citrus essential oils (yuzu peel oil) that some doctors prefer to avoid. If you're pregnant or nursing, look for a retinol-free overnight mask such as a hyaluronic acid or peptide-based sleeping pack.

No, it is not fungal-acne safe. The formula contains caprylic/capric triglyceride, hydrogenated lecithin, polysorbate 20, linoleic acid and several plant oils that can feed Malassezia yeast and worsen fungal-acne breakouts (small, uniform, itchy bumps on the forehead, chest or back). Choose a Malassezia-safe alternative like an azelaic acid or urea-based overnight treatment if you're prone to fungal acne.

The mask already contains retinol and vitamin C, so you usually don't need to layer additional ones on top β€” that can over-irritate skin. Avoid using a separate strong retinol or AHA/BHA on the same night to prevent compromising the skin barrier. Save your acid exfoliants (glycolic, lactic, salicylic) for a different evening, and use a dedicated stronger vitamin C serum in the morning instead. Niacinamide, hyaluronic acid and peptides layer perfectly underneath.

It works best for normal, combination, dry and mature skin types looking for a gentle anti-aging + brightening overnight step. The lightweight jelly is also workable for oily skin. Sensitive skin should patch-test first because of the citrus oils and retinol. If you have fungal acne or are pregnant, choose an alternative.

Most users notice plumper, softer, dewier skin the very next morning thanks to glycerin and silicones. Brightening and pore-refining effects from niacinamide and vitamin C typically show in 2–4 weeks of consistent use (3–5 nights per week). Retinol's line-smoothing and texture-refining effects build over 8–12 weeks.

Use it as the very last step of your evening routine β€” after cleanser, toner, essence, serum and moisturizer. The jelly mask acts as a sealing occlusive layer that locks everything underneath in place overnight. In the morning, rinse off and follow with a vitamin C serum (optional) and broad-spectrum SPF 30+.

Comedogenic rating: 2/5 β€” generally low-clogging. The formula is mostly water-based with humectants and silicones. However, caprylic/capric triglyceride, behenyl alcohol and a few plant oils may clog pores in very acne-prone individuals. The brand markets it as suitable for all skin types and we'd agree for most, but if you're extremely breakout-prone, monitor closely or patch test on the jawline first.

The Period After Opening (PAO) is 12 months β€” this is shown by the open-jar symbol with "12M" on the packaging. Because the formula contains ascorbic acid and retinol, both of which oxidize, it's ideal to finish the jar within 6–9 months for peak potency. If the product turns dark orange-brown or smells off, it has oxidized and should be replaced.

β˜…β˜…β˜…β˜…β˜†
4.4 out of 5

Verdict: Saturday Skin's Yuzu Vitamin C Sleep Mask is a smart, multi-tasking K-beauty overnight treatment that delivers immediate plumping glow plus a gentle, well-buffered dose of retinol, niacinamide and vitamin C. It's ideal for normal-to-combination, dry and mature skin looking for a single-step brightening + anti-aging finisher. The only meaningful drawbacks are jar packaging that exposes actives to air, slightly low concentrations for advanced users, and unsuitability for pregnancy and fungal-acne-prone skin. For everyone else, it's a deservedly award-winning sleeping pack with one of the most addictive citrus scents in skincare.

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.
