About

A no-nonsense serum for oily, blemish-prone skin. At 15% niacinamide with zinc and NAG, it works on excess oil, enlarged pores and post-acne dark marks all at once.

It's a workhorse rather than a luxury — used consistently, it quietly evens things out and calms the shine.

Is it right for your skin?

A quick look at who it suits and how to fit it in.

Skin type

Nairobi weather
