Treating acne often means using ingredients that help calm inflammation, balance oil, and support clearer skin.

Below are three serum‑style products that many people choose to support acne‑prone complexions — each with its own approach and benefits.

1. Some by Mi Yuja Niacin Anti Blemish Serum

This serum from Some by Mi combines niacinamide with blemish‑targeting ingredients to help soothe and reduce the look of breakouts. Some by Mi products are known for their acne‑focused formulas, often including AHA, BHA, and PHA to help gently exfoliate and unclog pores over time. Because it supports smoother skin texture and can help inflammation settle down, it’s a good choice for people dealing with occasional to frequent breakouts and uneven skin surface.

2. COSRX The Niacinamide 15 Serum

High‑strength niacinamide serums like this one are often recommended for oily or acne‑prone skin because niacinamide can help reduce excess oil, minimize the look of pores, and even out skin tone. According to tests and reviews, a niacinamide serum at this concentration can help improve breakouts and leftover marks from blemishes over weeks of consistent use.

3. La Roche Posay Effaclar Ultra Concentrated Serum

While La Roche‑Posay Cicaplast Baume B5+ itself is a balm that supports skin barrier repair and soothing more than a direct acne active, the Effaclar Ultra Concentrated Serum from the same brand is full of acne‑focused ingredients like salicylic acid and LHA to help unclog pores and smooth bumps. It’s formulated to help reduce the appearance of blemishes and refine texture while also being suitable for sensitive, breakout‑prone skin.

Together, these serums give you options ranging from gentler daily support to more active‑focused acne care — so you can build a routine that suits your skin’s needs without overwhelming it. Regular use (and patch tests if you have sensitive skin) can help you see improvement over time.
