Alpha hydroxy acids are organic compounds that are typically derived from natural sources such as fruits, sugars, and milk. They are widely used in skincare products for their exfoliating properties, helping to remove dead skin cells and promote cell turnover. This makes them particularly beneficial for achieving smoother skin texture and improving the appearance of fine lines and hyperpigmentation.

These acids, including glycolic acid (sourced from sugar cane) and lactic acid (sourced from milk), play a crucial role in cosmetic formulations due to their ability to enhance skin moisture levels and stimulate collagen production. Their effectiveness and gentle nature make alpha hydroxy acids a popular choice in many esthetic treatments and home care routines.

In contrast, salicylic acids are primarily derived from willow bark and have properties better suited for oil control and acne treatment. Beta hydroxy acids are also suitable for oily skin but are derived from different sources and have a different pH level and solubility profile, making them less common in formulations focused on hydration and exfoliation from fruits and milk. Hydrochloric acids, on the other hand, are synthetic and not relevant in the context of fruit and dairy extraction.
