This fit is calculated for the concerns frequently associated with oily acne-prone skin: shine, breakouts, blemishes, and enlarged pores. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for oily acne-prone skin; other serums fit it better.

## Why this fit

- Highly suitable for your oily skin, niacinamide helps regulate sebum and reduce inflammation, while sodium hyaluronate provides essential hydration. Phenylethyl resorcinol and niacinamide offer moderate brightening and improve skin tone, though these benefits are secondary to your primary concerns of acne and breakouts.
- The formula provides general hydration with glycerin, which is supportive but not directly targeted at managing your acne, blemishes, and breakouts.
- The product is safe for your oily skin, with no risks of irritation due to the absence of harsh or prohibited ingredients.

## Questions and answers

### How well does La Roche-Posay Pure Niacinamide 10 work for oily acne-prone skin?

La Roche-Posay Pure Niacinamide 10 Serum works moderately well for oily acne-prone skin, helping control oil and calm inflammation while providing general hydration, though other options target breakouts more directly. A treatment for this skin type needs targeted ingredients that manage excess oil and acne directly while keeping the skin comfortable and balanced daily.

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

Niacinamide and sodium hyalronate make this serum a good fit for oily acne-prone skin because niacinamide helps control oil and calm inflammation while sodium hyaluronate provides essential hydration. Treatments that fit this skin best need ingredients like propolis, vitamin C, and soothing extracts that directly target breakouts and excess oil while remaining light and comfortable for daily use.

### 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.

### What does Thermal Water do for oily acne-prone skin?

Thermal water helps calm oily, acne-prone skin by reducing dryness, stinging, and redness while improving overall skin comfort. It is useful as an extra step in your routine because it supports hydration and makes acne treatments more gentle on the skin.
Sources: [The Medical Journal of Malaysia, 2024](https://pubmed.ncbi.nlm.nih.gov/38553920/), [Journal of Cosmetic Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17348993/)

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

This serum goes in the evening routine after cleansing and before moisturizing, which keeps it simple and safe around sun exposure. This type of skin needs a treatment with ingredients like salicylic acid or benzoyl peroxide that directly target acne, blemishes, and breakouts.

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

You can use this serum with retinol by applying the treatment after cleansing and before your moisturizer in your evening routine. This helps keep your oily skin calm and hydrated while minimizing any irritation.

### How often should I use this serum?

You can use this treatment in your evening routine, applying it then for simplicity and extra safety around sun exposure. This product works for your skin, though an oily acne-prone skin type needs targeted ingredients like salicylic acid or benzoyl peroxide to directly manage acne and breakouts.

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

This serum is unlikely to cause breakouts on oily skin, as it has a safe formula with no harsh ingredients. However, because it is only an average fit for your skin type, an ideal product for your breakouts needs targeted blemish-fighting ingredients and oil-balancing agents to better manage acne.

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

It contains fragrance (parfum) and drying alcohol (alcohol denat).
