Journal of Drugs in Dermatology, 2015Postepy Dermatologii I Alergologii, 2023
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.
Where does this serum go in a skincare routine for acne-prone skin?
This treatment serum goes in your evening routine after cleansing and toning, and before moisturizing. Putting treatments in the evening helps keep things simple and adds safety around sun exposure.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying them on alternate nights or spacing them out to keep your skin calm and avoid irritation. Because both ingredients work actively on blemishes, introducing them slowly helps your skin adjust safely.
How often should I use this serum?
You can use this treatment serum in your evening routine, applying it once a week at first and carefully building up to more often if your skin tolerates it well. Azelaic acid and niacinamide help calm redness and clear pores while snail mucin keeps skin hydrated, making it very suitable for acne-prone skin.
Can this serum clog pores, cause breakouts or purging for acne-prone skin?
This serum is a great fit for your acne-prone skin because azelaic acid and niacinamide help calm redness and keep pores clear. Initial breakouts or purging are unlikely with this formula, and snail mucin helps keep your skin hydrated while supporting healing.
