## Questions and answers

### How well does Paula's Choice Discoloration Repair Serum work for acne-prone skin?

This serum works moderately well for acne-prone skin, providing hydration and evening skin tone, though other options may fit this skin type better. To work best for acne-prone skin, a treatment of this type needs ingredients like niacinamide and soothing plant extracts that calm blemishes and control oil without causing irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

This serum fits acne-prone skin through niacinamide and tranexamic acid, which help even out skin tone and manage oil, while glycerin and bakuchiol provide calming hydration and blemish support. To work best for this skin type, a treatment of this kind needs ingredients like niacinamide and soothing plant extracts or zinc that target breakouts without any irritation risk while keeping moisture balanced.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

### What does Tranexamic Acid do for acne-prone skin?

Tranexamic acid helps calm red marks left behind by breakouts and reduces inflammatory bumps like pimples on acne-prone skin. It is unlikely to cause irritation and works well to improve uneven skin tone without significant side effects.
Sources: [Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35388589/), [Journal of Research in Medical Sciences, 2023](https://pubmed.ncbi.nlm.nih.gov/37213446/)

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

Niacinamide helps acne-prone skin by reducing both inflamed and uninflamed breakouts and calming redness. It is also very helpful for keeping oily skin balanced by cutting down on excess oil production, and it is well tolerated by most people.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38299457/), [Cureus, 2024](https://pubmed.ncbi.nlm.nih.gov/38725769/)

### Where does it go in a skincare routine for acne-prone skin?

This treatment goes in your evening routine, as treatments with active ingredients are typically used then for simplicity and extra safety around sun exposure. A product for acne-prone skin needs soothing and hydrating ingredients to calm blemishes while minimizing irritation risks.

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

You can use this treatment with retinol by applying the treatment first and following with your retinol on alternate nights or separate times to minimize irritation risks. Because this skin needs gentle hydrating and calming ingredients that balance oil without heavy irritation risks, combining potent actives requires careful spacing.

### How often should I use it?

You can use this treatment in your evening routine, applying it once a week at first and carefully increasing frequency if your skin tolerates it well. This gradual approach helps you manage any potential irritation while still benefiting from the brightening ingredients. For this skin type, a product also needs soothing plant extracts and gentle hydrators to keep breakouts calm and comfortable.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

This serum works for acne-prone skin, though other products fit it better because this skin needs ingredients that regulate oil and soothe without irritation risks like AHAs. It is generally safe, but can occasionally pose a mild irritation risk or cause breakouts if your skin is sensitive to rich textures. To properly care for acne-prone skin, a product of this type needs soothing ingredients like niacinamide and gentle plant extracts that calm redness while keeping pores clear.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Clinical, Cosmetic and Investigational Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/25914553/)

### Is it fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Behenyl alcohol is a fatty alcohol, which soften the skin.
