## Why this fit

- Offers moderate exfoliation for your oily skin, as citric acid and gluconolactone work to gently remove dead skin cells and improve texture, while niacinamide supports your skin barrier and helps regulate oil production.
- Glycerin provides essential hydration, which is beneficial for managing acne and breakouts without exacerbating oiliness.
- The product is safe for your oily skin, with no harsh ingredients that could cause irritation.

## What reviewers say

Users with hyperpigmentation and dullness frequently praise this cleanser for its ability to gently exfoliate and smooth skin texture without stripping moisture. While many report a brighter, more radiant complexion, a subset of users with stubborn dark spots found it ineffective or were put off by its fragrance and residual film.

- Liked: Gentle and non-drying (mostly mentioned)
- Liked: Pleasant usage experience (often mentioned)
- Liked: Smoothes skin texture (often mentioned)
- Liked: Brightens complexion (sometimes noted)
- Disliked: Ineffective on spots (sometimes noted)
- Disliked: Caused irritation (rarely noted)
- Disliked: Leaves a film (rarely noted)
- Disliked: Strong fragrance (rarely noted)

## How to apply

- Use this exfoliant as part of your PM routine once a week to start, increasing frequency only if your skin tolerates it well.
- Apply the exfoliant after cleansing and toning, but before your final moisturizer step.
- Gently press 2-3 drops of the exfoliant into your skin and let it absorb for a minute.
- Apply the product directly onto clean, dry skin for the best results against breakouts.
- Avoid the sensitive eye area and always use a daily SPF since exfoliating makes skin more sensitive to the sun.

## Questions and answers

### How well does La Roche-Posay Mela B3 Micro-Peeling Gel work for oily acne-prone skin?

La Roche-Posay Mela B3 Brightening Micro-Peeling Gel works as an average fit for oily acne-prone skin, gently removing dead skin cells and supporting the skin barrier with niacinamide and gluconolactone while providing essential hydration.

Sources: [Skin Research and Technology, 2023](https://pubmed.ncbi.nlm.nih.gov/37357656/), [The Australasian Journal of Dermatology, 1992](https://pubmed.ncbi.nlm.nih.gov/1303072/)

### Which ingredients make this exfoliant a good fit for oily acne-prone skin?

Citric acid and gluconolactone gently remove dead skin cells and improve texture, while niacinamide helps regulate oil production and glycerin provides lightweight hydration. An exfoliant of this type for oily acne-prone skin needs effective ingredients like benzoyl peroxide or vitamin C that target breakouts and control oil without causing irritation.

### What does Niacinamide do for oily acne-prone skin?

Niacinamide helps balance oil production, calms redness, and is unlikely to irritate oily, acne-prone skin while improving blemishes. Clinical tests show it reduces excess oil and helps clear up both inflammatory and non-inflammatory acne breakouts.
Sources: [Journal of Cosmetic and Laser Therapy, 2006](https://pubmed.ncbi.nlm.nih.gov/16766489/), [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38299457/)

### What does Polyhydroxy Acid do for oily acne-prone skin?

Polyhydroxy Acid helps clear mild to moderate acne by reducing both inflamed and non-inflamed spots similarly to stronger treatments while keeping your skin calm and comfortable. It is unlikely to cause irritation or damage your skin barrier, making it a well-tolerated choice for oily and acne-prone skin.
Sources: [The Australasian Journal of Dermatology, 1992](https://pubmed.ncbi.nlm.nih.gov/1303072/), [Journal of Cosmetic Dermatology, 2010](https://pubmed.ncbi.nlm.nih.gov/20367666/)

### Where does this exfoliant go in a skincare routine for oily acne-prone skin?

This exfoliant treatment goes in the evening routine, starting at once a week so your skin can adjust. Oily acne-prone skin works best with products that gently remove dead skin cells and control oil without causing irritation.

### Can I use this exfoliant with retinol, and in what order?

This exfoliant is best used on different nights than your retinol to keep your oily skin calm and prevent irritation. Applying both active treatments at the same time can be too strong and may dry out your skin.

### How often should I use this exfoliant?

Start by using this exfoliant once a week, and if your oily skin tolerates it well and shows good results, you can carefully use it more often. A product of this type needs gentle exfoliating ingredients like acids along with barrier-supporting ingredients to smooth your skin and help manage breakouts without causing irritation.

### Can this exfoliant clog pores, cause breakouts or purging for oily acne-prone skin?

La Roche-Posay Mela B3 Brightening Micro-Peeling Gel is unlikely to clog pores or cause breakouts on your oily acne-prone skin, as it contains gentle exfoliating acids and hydrating ingredients that help manage oil without causing irritation. To truly clear acne and control oil on this skin type, a product needs a blend of soothing exfoliants like salicylic acid or niacinamide to clear pores and keep oil balanced.

### Is this exfoliant fragrance-free and alcohol-free?

It has no drying alcohol and contains fragrance (parfum).
