How to use
Use daily, morning and night. Apply a small amount to wet skin, massage until it foams, then rinse. Avoid direct contact with eyes. Do not use on children. Store in a cool, dry place.
Ingredients Highlights
- Salicylic Acid (2% BHA): A beta-hydroxy acid with antibacterial and antifungal properties. Helps exfoliate the outer layer of the skin by removing dead cells, supports oil control, and helps reduce the appearance of blackheads and blemishes. Its keratolytic action may also help improve skin permeability, supporting better integration of complementary skincare actives.
- Glycerin (5%): A hydrophilic organic compound widely recognized as a highly effective humectant. Helps attract and retain water to support hydration and comfort. Beyond surface moisturization, glycerin can penetrate the skin barrier and help maintain hydration in deeper layers for longer-lasting softness.
- Cleansing Surfactants (Tensoativos): Ingredients designed to break down and emulsify oils and debris, suspending particles so they rinse away easily with water. Surfactants may be classified as cationic, anionic, non-ionic, or amphoteric depending on the ions they form in aqueous solution—helping formulators balance cleansing performance with skin feel.
Allergen warnings / cautions
- For external use only. Discontinue use if irritation occurs.
- Avoid direct contact with eyes.
- If you are sensitive to exfoliating acids, start once daily and increase as tolerated.
- Use sunscreen during the day when using exfoliating acids in your routine.
