Gentle Chemical Exfoliation

Lactic acid (AHA) dissolves dead skin cells without harsh scrubbing, improving texture and radiance with each use.

Brightening & Evening

5% niacinamide visibly reduces blemishes, minimizes pore appearance, and brightens overall complexion for a unified skin tone.

Hydrating Support

Squalane, glycerin, and trehalose work together to lock in moisture while the acids exfoliate, preventing dryness and irritation.

Clean & Responsible Formula

Free from parabens, sulfates, phthalates, and mineral oil. Packaged in a recyclable bottle made with 40% recycled glass.

02

Safety & compatibility

SAFE
Pregnancy & Breastfeeding

Contains lactic acid (AHA). Low-concentration AHAs are generally considered low-risk, but consult your OB-GYN before use during pregnancy or nursing. No retinoids, salicylic acid, or hydroquinone present.

Fungal Acne (Malassezia) Safe

Formula does not contain common malassezia-feeding triggers such as fatty acids (C11–C24), polysorbates, or fermented ingredients. Squalane is confirmed fungal acne safe.

Low Comedogenic Risk (1/5)

Core ingredients like glycerin (0), squalane (0), and niacinamide (0) score very low on the comedogenic scale. Unlikely to clog pores.

Sun Sensitivity Warning

This product contains an AHA which may increase sun sensitivity. Always apply broad-spectrum SPF 30+ the following morning. Limit sun exposure during use and for one week after stopping.

Sensitive Skin Friendly

Lactic acid is the gentlest AHA due to its larger molecular size. Clinical trials on 32 volunteers showed no significant irritation. Patch test recommended for very reactive skin.

Allergen & Irritant Free

No artificial fragrances, essential oils, parabens, sulfates, phthalates, or mineral oil. Meets Sephora's "Clean at Sephora" standard.

Ingredient breakdown

INGREDIENTS

Niacinamide (Vitamin B3) 5%Proven

A multi-functional skincare superstar that targets blemishes, congested pores, uneven tone, and fine lines. At 5%, it delivers optimal brightening and pore-minimizing benefits backed by decades of clinical research.

  • Brightening: Inhibits melanin transfer to reduce dark spots and post-inflammatory hyperpigmentation.
  • Pore Minimizing: Regulates sebum production, visibly shrinking enlarged pores over 8–12 weeks.
  • Barrier Support: Boosts ceramide and fatty acid synthesis, strengthening the skin barrier.
  • Anti-Aging: Stimulates collagen production and reduces fine lines at 4–5% concentration.
Well-tolerated at 5% for all skin types. Works synergistically with AHAs like lactic acid for enhanced exfoliation and brightening.

Lactic Acid (AHA) ~2–4%Proven

The gentlest alpha hydroxy acid, derived from milk. Its larger molecular size means it penetrates less deeply than glycolic acid, making it ideal for sensitive skin while still delivering effective exfoliation.

  • Exfoliation: Dissolves the "glue" between dead skin cells to reveal smoother, brighter skin underneath.
  • Humectant: Doubles as a moisture-attracting ingredient, drawing water into the skin while exfoliating.
  • Texture: Clinically shown to improve skin smoothness by 28% after 28 days of use in this formula.
Contains AHA — always use sunscreen the morning after application. May cause mild tingling on first use; this is normal and subsides as skin acclimates.

Squalane SupportingProven

A highly stable, plant-derived emollient that mimics the skin's natural sebum. Provides lightweight moisture without clogging pores or triggering breakouts. Fungal acne safe and suitable for all skin types.

  • Barrier Repair: Reinforces the skin's lipid barrier while actives exfoliate, preventing moisture loss.
  • Non-Comedogenic: Comedogenic rating of 0 — excellent for acne-prone and oily skin.

Glycerin SupportingProven

One of the most effective humectants in skincare. Draws moisture from the environment into the skin and helps maintain the skin lipid barrier in a healthy liquid-crystal state.

  • Hydration: Effective from 3% concentration upward, with increased benefits at higher levels.
  • Barrier: Protects against irritation and helps restore skin barrier — especially important alongside exfoliating acids.

Trehalose SupportingPromising

A natural sugar with exceptional moisture-retaining properties. Acts as a stress-protectant for skin cells, helping them maintain hydration even in harsh environmental conditions.

  • Cell Protection: Stabilizes cell membranes under stress from exfoliation, UV, and dehydration.
  • Moisture Lock: Superior water-binding ability compared to many traditional humectants.

Tocopherol (Vitamin E) SupportingProven

A potent antioxidant that protects newly revealed skin from free radical damage. Works synergistically with niacinamide to enhance overall skin health and reduce signs of oxidative stress.

  • Antioxidant: Neutralizes free radicals that accelerate skin aging.
  • Healing: Supports skin repair and reduces post-inflammatory redness.

How to use

HOW TO USE
1

Cleanse & Dry

Wash your face with a gentle cleanser and pat skin completely dry. Applying to dry skin ensures the acid works evenly and reduces potential irritation.

2

Apply 2–3 Drops

Pump a small amount onto fingertips and gently massage over the face, avoiding the eye contour area. A little goes a long way with this concentrated formula.

3

Let It Absorb

Allow 30–60 seconds for the serum to fully absorb before layering additional products. You may feel a slight tingle — this is normal and indicates the lactic acid is working.

4

Follow with Moisturizer

Apply your evening moisturizer to lock in hydration. In the morning, always apply SPF 30+ as AHAs increase sun sensitivity.

5

Build Up Gradually

Start with every other night for the first 2 weeks. Once your skin adjusts, you can increase to nightly use. If excessive dryness or irritation occurs, reduce frequency.

06

Who is it for?

WHO

Perfect for you if:

  • You want a gentle introduction to chemical exfoliation
  • Your skin looks dull and you want overnight radiance
  • You struggle with congested pores and uneven texture
  • You have sensitive or combination skin that reacts to stronger acids
  • You prefer a clean, fragrance-free formula at an affordable price
  • You want visible brightening without the irritation of glycolic acid

Consider alternatives if:

  • You need intense, high-percentage acid exfoliation (10%+ AHA)
  • You have very dry skin and need a richer, more hydrating formula
  • You want anti-aging benefits like significant wrinkle reduction
  • You are already using prescription retinoids — adding AHA may over-exfoliate
  • You want a larger bottle size — 30ml may run out quickly with daily use
07

Skin type compatibility

SKIN TYPES
Oily Skin
Excellent

Lightweight formula absorbs quickly without adding shine. Niacinamide helps regulate excess sebum and minimize pore appearance.

Combination Skin
Excellent

Balances well across different face zones. Exfoliates oily T-zone while hydrating drier cheek areas with squalane and glycerin.

Normal Skin
Excellent

Delivers a healthy glow and improved texture. The gentle concentration is ideal for maintaining smooth, clear skin without overdoing it.

Sensitive Skin
Good

Fragrance-free and formulated with the gentlest AHA. Some users with eczema report mild tingling that subsides quickly. Patch test first.

Dry Skin
Moderate

The formula provides some hydration via squalane and glycerin, but very dry skin may need a heavier moisturizer on top. Some dry-skin users report it feels too gentle.

Acne-Prone Skin
Excellent

Non-comedogenic (1/5), fungal acne safe. Niacinamide targets blemishes while lactic acid keeps pores clear and prevents congestion.

DUPES
82% Match
Lactic Acid 5% + HA
$6.80

Similar gentle lactic acid approach with added hyaluronic acid for hydration. Higher transparency on concentration (5% LA). Lacks niacinamide and squalane — simpler formula, runnier texture.

72% Match
Hyaluronic Acid Serum
$10.99
Budget Pick

Contains 10% lactic acid — stronger exfoliation than the Sephora serum. Also includes hyaluronic acid. No niacinamide. More likely to cause tingling or irritation for sensitive skin. Squeeze tube packaging.

68% Match
AHA 7 Whitehead Power Liquid

Frequently asked questions

FAQ

This serum contains lactic acid, which is an AHA. While low-concentration AHAs are generally considered low-risk during pregnancy, many dermatologists advise caution. The formula does NOT contain retinoids, salicylic acid (BHA), hydroquinone, or chemical sunscreens — all of which are commonly flagged during pregnancy. We recommend consulting your OB-GYN or dermatologist before incorporating any AHA product into your routine while pregnant or breastfeeding.

Yes. This serum is considered fungal acne safe. It does not contain common malassezia-feeding triggers such as fatty acids in the C11–C24 range, polysorbates, or fermented ingredients. The squalane in the formula is confirmed safe for fungal acne-prone skin. SkinSort also classifies this product as fungal acne safe based on its ingredient analysis.

Use caution when combining with other active ingredients. Avoid using this serum on the same night as retinol/retinoids or other AHA/BHA products to prevent over-exfoliation and irritation. You can alternate nights (e.g., retinol on Monday, this serum on Tuesday). Vitamin C (L-ascorbic acid) at low pH may cause stinging if layered directly — apply vitamin C in the morning and this serum in the evening for the best results.

This serum is formulated for all skin types: normal, dry, combination, and oily. It excels on oily, combination, and acne-prone skin thanks to its lightweight, non-greasy texture and pore-refining niacinamide. Sensitive skin users report good tolerance due to the gentle lactic acid concentration. Very dry skin may find it insufficient on its own — pair with a rich moisturizer.

Many users report noticing an immediate glow and softer skin after the first overnight application. Clinical testing showed measurable improvements in 28 days: 31% more even complexion and 28% smoother skin. For maximum brightening and blemish-fading benefits from niacinamide, allow 8–12 weeks of consistent use.

Apply in the evening after cleansing and toning, on clean, dry skin. This serum should go before heavier serums, moisturizers, and face oils. The community recommends it as step 3 in a 5–6 step routine: Cleanser → Toner → This Serum → Moisturizer → SPF (morning). 93% of users apply it exclusively in the evening.

No. This serum has a comedogenic rating of 1 out of 5, meaning it is very unlikely to clog pores. Key ingredients like glycerin (0), squalane (0), and niacinamide (0) all score at the lowest end of the comedogenic scale. The lactic acid actively helps keep pores clear by dissolving dead skin cell buildup. It is safe for acne-prone skin.

The serum has a Period After Opening (PAO) of 12 months. The 30ml bottle typically lasts 2–3 months with nightly use (2–3 drops per application). Store in a cool, dry place away from direct sunlight to maintain potency. The opaque glass bottle helps protect the formula from light degradation.

— Skincarisma verdict
4.2 / 5 ★★★★☆

Verdict: The Sephora Collection Gentle Peeling Serum is an excellent entry-level exfoliating serum that delivers on its promise of smoother, brighter skin — especially for sensitive and combination skin types. The combination of 5% niacinamide with gentle lactic acid provides a well-rounded approach to texture refinement, pore minimization, and tone evening without the irritation of stronger acid formulas. At its price point, it offers genuine clinical-backed results (31% more even complexion in 28 days) in a clean, fragrance-free, fungal acne safe formula. The main drawback is the small 30ml size, which feels modest for nightly use. Experienced chemical exfoliation users may find it too mild. For beginners or those with reactive skin seeking their first AHA serum, this is a smart, affordable, and effective choice.

lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

question
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.
