The IsNtree Hyper Acid4 AHA BHA PHA LHA 30 Serum (Wash Off) is a powerhouse exfoliating serum designed to promote smooth and clear skin. Let’s break down its components: Ingredients: *AHA (Alpha Hydroxy Acid): This group includes acids like glycolic acid, lactic acid, and more. AHA targets the skin’s surface, exfoliating dead skin cells, improving texture, and addressing hyperpigmentation. *BHA (Beta Hydroxy Acid): BHA, including salicylic acid, is oil-soluble and penetrates deeper to unclog pores, reduce oil production, and treat acne and blackheads. *PHA (Poly Hydroxy Acid): PHA has larger molecular structures, making it gentler. It’s suitable for sensitive skin and provides exfoliation while retaining moisture. *LHA (Lipo Hydroxy Acid): Derived from salicylic acid, LHA is also gentle and effective for exfoliating acne-prone skin. Charcoal Powder: Balances oil-water levels and helps clear clogged pores. Benefits: A rinse-off serum helps smooth skin and thoroughly removes dead skin cells with sebum control function.
