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.
Safety & compatibility
SAFEContains 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.
Formula does not contain common malassezia-feeding triggers such as fatty acids (C11–C24), polysorbates, or fermented ingredients. Squalane is confirmed fungal acne safe.
Core ingredients like glycerin (0), squalane (0), and niacinamide (0) score very low on the comedogenic scale. Unlikely to clog pores.
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.
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.
No artificial fragrances, essential oils, parabens, sulfates, phthalates, or mineral oil. Meets Sephora's "Clean at Sephora" standard.
Ingredient breakdown
INGREDIENTSNiacinamide (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.
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.
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.

Where it fits in your routine
ROUTINEUse in the evening after cleansing. 93% of users apply this as an evening-only treatment. Always follow with SPF the next morning.
How to use
HOW TO USECleanse & 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.
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.
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.
Follow with Moisturizer
Apply your evening moisturizer to lock in hydration. In the morning, always apply SPF 30+ as AHAs increase sun sensitivity.
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.
Who is it for?
WHOPerfect 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
Skin type compatibility
SKIN TYPESLightweight formula absorbs quickly without adding shine. Niacinamide helps regulate excess sebum and minimize pore appearance.
Balances well across different face zones. Exfoliates oily T-zone while hydrating drier cheek areas with squalane and glycerin.
Delivers a healthy glow and improved texture. The gentle concentration is ideal for maintaining smooth, clear skin without overdoing it.
Fragrance-free and formulated with the gentlest AHA. Some users with eczema report mild tingling that subsides quickly. Patch test first.
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.
Non-comedogenic (1/5), fungal acne safe. Niacinamide targets blemishes while lactic acid keeps pores clear and prevents congestion.

Criticized
- Small 30ml bottle size feels inadequate for the price with daily use
- Pump mechanism may fail before all product is dispensed
- Effects too subtle for experienced chemical exfoliation users
- Not moisturizing enough for very dry skin types on its own
- Lactic acid concentration not disclosed — less transparency
- Some users felt no noticeable peeling or exfoliation happening
Budget-friendly alternatives (dupes)
DUPESSimilar gentle lactic acid approach with added hyaluronic acid for hydration. Higher transparency on concentration (5% LA). Lacks niacinamide and squalane — simpler formula, runnier texture.
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.
Uses 7% glycolic acid instead of lactic acid — more potent exfoliation but potentially more irritating. Includes niacinamide. Better for oily skin. Larger 100ml bottle offers much better value per ml.

Frequently asked questions
FAQThis 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.
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.

Quick Product Notes
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.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients

Ingredients Related to Skin Types
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.
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.
