A dual-chamber benzoyl peroxide and retinol treatment for adult, blemish-prone skin. 30ml.
Jan Marini Age Intervention Duality is a clever dual-chamber treatment that pairs benzoyl peroxide (BPO) with retinol (vitamin A), designed for adult skin that's both blemish-prone and showing the look of ageing. It helps clear the look of blemishes while smoothing the look of fine lines, in one considered step.
Why you'll love it
- Dual-chamber benzoyl peroxide and retinol
- Clears the look of blemishes and smooths fine lines
- Designed for adult, blemish-prone skin
- Two actives in one step
How to use: Apply as directed. Introduce gradually; BPO can cause dryness and bleach fabrics/hair, and retinol increases sun sensitivity, so always use SPF by day. Patch-test first. Not recommended during pregnancy or breastfeeding.
Who it's for: Adult, blemish-prone skin.
