How to use
Use daily, only at night. Apply to clean, dry skin before creams. Saturate a cotton pad or soft cloth and sweep gently over the face, avoiding the eye area.
Do not apply on eyelids, on the outer corners of the nose and mouth, or on irritated/broken skin. Avoid sun exposure during use and wear sunscreen daily.

Ingredients Highlights
- Salicylic Acid (1% BHA): A beta-hydroxy acid with antibacterial and antifungal properties. Helps exfoliate the outer layer by removing dead cells, supports oil control, and helps reduce the appearance of blackheads and blemishes. Its keratolytic action may also support better integration of complementary skincare ingredients.
-
Lactic Acid (7% AHA): Originally derived from lactose and also synthesizable from plant-derived ingredients such as sucrose and glucose. As an AHA with a larger molecular size, it tends to penetrate more slowly and can provide a gentler-feeling chemical exfoliation than some other AHAs. Lactic acid also acts as a humectant and is part of the skin’s natural moisturizing factors, supporting hydration while refining the look of texture and oiliness.
