Succinic acid

Succinic acid, the amber acid, a newer name in care for oily, blemish-prone skin.

What it is: An acid found in amber and made by fermentation for skincare.
What it does: Used in blemish serums, toners, peeling pads and cleansers for clearer-looking pores and less shine.
How often: Daily in most cleansers and hydrating skincare; acid treatments may need a slower start, with the peeling ampoule used in the evening. Masks are weekly care, spot patches are used when needed, and foundation is applied with makeup.
