medicube Red Succinic Acid Serum 30ml

A 30 ml serum pairing succinic acid, an ingredient Korean brands moved to for congested skin, with niacinamide for the marks left afterwards. The two concerns usually arrive together, which is why this is one bottle rather than two. The brand states the formula is non-comedogenic.

Who it's for. Blemish-prone skin and the appearance of uneven tone where breakouts have left marks behind.

How to use. After toner, press two to three drops over face and neck. Follow with moisturiser, morning and evening, and wear sunscreen in the day, since sun makes marks look darker for longer.

Key active. Succinic acid with niacinamide. Niacinamide works on the appearance of uneven tone; in Korean cosmetics, whitening language means evenness of tone, not lightening your natural colour. The brand does not publish a percentage, and we are not going to invent one.
