Blackberry Retinol Blemish Serum

Serum · 29 ingredients

A blemish-targeting serum formulated for oily, combination, and normal skin prone to acne. A triple-retinoid blend of retinol, retinal, and retinyl ester works to diminish the appearance of blemishes while visibly resurfacing texture and pores, while blackberry extract supports the skin's natural barrier-healing process. Glycerin and ectoin help calm and hydrate blemish-prone or sensitive skin, making the formula gentle enough for nightly use.
