COSRX The AHA BHA PHA LHA 35 Peel has:
* Multi-acid formula (AHA, BHA, PHA, LHA): This is the key selling point. The product contains a blend of different types of hydroxy acids, each with a slightly different function and molecular size.
* AHA (Alpha Hydroxy Acid): Exfoliates the surface of the skin, helping to improve skin texture, tone, and brightness. Glycolic acid and lactic acid are common examples.
* BHA (Beta Hydroxy Acid): Salicylic acid is the most common BHA. It's oil-soluble, which means it can penetrate into pores to exfoliate and help with blackheads and breakouts.
* PHA (Poly Hydroxy Acid): Larger molecules than AHAs, making them less irritating. They provide gentle exfoliation and also have humectant properties, meaning they attract water to the skin. Gluconolactone and lactobionic acid are PHAs.
* LHA (Lipo-Hydroxy Acid): A derivative of salicylic acid. It's very gentle and exfoliates slowly and on the surface, making it suitable for sensitive skin.
* Contains Panthenol (B5) and Vitamin B12: These ingredients are included to soothe and hydrate the skin, which is important when using exfoliating acids. Panthenol is a well-known calming and moisturizing ingredient, and Vitamin B12 is often used for its skin-soothing properties.
The COSRX AHA BHA PHA LHA 35 Peel is a powerful exfoliating treatment that combines a variety of acids to address multiple skin concerns. The combination of exfoliants and soothing ingredients like Panthenol and Vitamin B12 is a well-thought-out formula. For many people, this type of product can be highly effective at improving skin texture and tone. However, due to its potency, it's important to use it with caution and as directed to avoid irritation.
The primary downside of the COSRX AHA BHA PHA LHA 35 Peel is its high strength. The 35% acid concentration makes it very potent and increases the risk of irritation, redness, and over-exfoliation, especially for sensitive skin or new users. It's not suitable for everyone and requires careful usage, strict adherence to a sun protection routine, and a healthy skin barrier to avoid negative side effects.
