The SOS spot serum is designed for local work on individual imperfections. It is not a full-face product: apply it precisely to blemishes in the evening, as a boost to the core routine.
The formula combines niacinamide, Zinc PCA and salicylic acid with centella, horse chestnut extract and tea tree oil — ingredients traditionally used for blemish-prone skin. Apply before SOS Rescue Balm.
