An acid serum that clears breakouts and smooths early signs of aging
SkinCeuticals Blemish + Age Defense is an exfoliating serum for oily and combination skin that deals with breakouts and early signs of aging at the same time. Dioic acid helps control sebum and limits the marks breakouts leave behind, while salicylic and glycolic acids clear pores and smooth rough texture. LHA, a gentle salicylic acid derivative, adds a slow, deep exfoliation that also softens fine lines, which makes it a strong match for adults who still get blemishes.
The texture
A clear, watery serum that dries in seconds with a fresh, slightly cooling feel. It is oil-free and leaves no residue. It layers easily under a light moisturizer.
Who it suits
- Adults with oily or combination skin and recurring breakouts
- Enlarged pores and uneven texture
- Skin showing both blemishes and first fine lines
- Anyone who needs a lightweight, oil-free treatment
Worth knowing before you buy: Alcohol is the first ingredient and the acids can dry or sting sensitive skin, so start once a day. Wear sunscreen every morning and avoid stacking it with other peels or strong retinoids on the same night.
How long one bottle lasts
With 3 to 5 drops once or twice a day, the 30ml bottle lasts about 2 months.
