What Mandelic Acid does

The largest, slowest AHA. Dermatologists often pick it for melanin-rich Indian skin tones because it treats acne and pigmentation with a lower risk of post-inflammatory darkening.

What Niacinamide does

An all-rounder that controls oil, strengthens the skin barrier, reduces redness and evens out tone. It gets along with almost every other active, which is why it is in so many routines.

Frequently asked questions

Can I use Mandelic Acid and Niacinamide together?

Which goes first, Mandelic Acid or Niacinamide?

Apply Mandelic Acid first, then Niacinamide. The general rule is thinnest to thickest texture, and lowest pH first.

Should I use Mandelic Acid in the morning or at night?

Mandelic Acid: best at night. Use 3–4 nights a week. It is mild enough that many people can use it more often than other acids.

Niacinamide: works morning or night. Use morning, night or both, after water-based serums. 4–5% is enough for most people. Very high percentages can cause flushing on sensitive skin.
