Bio Balance Deep Peeling AHA10% + BHA2% + RED ALGAE Super Serum 30mla water-based exfoliating serum with AHA and BHA acids and red algae helps improve skin texture and radiance. Its key ingredients glycolic acid, lactic acid, mandelic acid, salicylic acid and red algae help exfoliate skin through multiple layers. AHA acids, or alpha hydroxy acids, are water-soluble acids that act on the surface of the skin. AHA 10% helps to gently exfoliate the top layer of the skin by removing dead skin cells, moisturizing the skin and reducing the signs of aging. BHA acids, or beta hydroxy acids, penetrate deeper into the skin layers and help open clogged pores, clear comedones and regulate sebum secretion. BHA acid is also ideal for problematic and acne-prone skin because it has antibacterial and anti-inflammatory effects.
