Actives of the month

Three actives. One mission.

Pigmentation isn't a one-size-fits-all concern. Different types of dark spots develop through different biological mechanisms, and understanding them is the first step towards more targeted skincare.

Meet three active ingredients selected for their complementary approaches to uneven skin tone.

Understanding dark spots

Not every dark spot has the same origin.

Two marks can look alike on the surface and have very different stories underneath. What set the pigment in motion decides which active is best placed to help.

  1. 01

    Sun exposure

    UV light prompts the skin to produce more melanin as a defence. Over the years, that pigment can gather into visible sun spots.

  2. 02

    Hormonal shifts

    Hormonal changes can make pigment cells more reactive, giving larger, more diffuse patches that often deepen with sun and heat.

  3. 03

    After inflammation

    A blemish or an irritation can leave a mark behind, as the skin responds to inflammation by laying down extra pigment.

Meet the actives

Three ingredients. Three mechanisms.

How they work together

Decode your pigmentation.
