What to Pair It With

−
The skincare industry would have you believe you need a dozen serums layered in the right order. You do not. Most people do better with a short routine they can actually keep up with. Three things are all you need alongside any active ingredient.
Moisturizer: Use one every time you use an active. It is not an optional extra. It is usually what decides whether you can keep using the active at all.
Sunscreen: Every morning. Many actives make skin burn more easily, and sun undoes the tone and texture work you are using them for.
A gentle cleanser: Plain is fine. Its job is to clean without stripping, so the rest of the routine has something to work with.
