Which of the following best describes AHA?

Heavy minerals used for moisturizing
Compounds derived from synthetic sources
Acids derived from plants, primarily used for exfoliation
Gel-based substances for hydration

The correct answer is: Acids derived from plants, primarily used for exfoliation

AHA, or alpha hydroxy acids, are indeed acids derived from natural sources, primarily fruits and plants. They are widely recognized in the field of esthetics for their exfoliating properties. AHAs help to loosen the bonds between dead skin cells on the surface, allowing them to shed more easily and promoting a smoother, more radiant appearance. This chemical exfoliation can aid in improving the texture of the skin, enhancing moisture retention, and reducing the appearance of fine lines and pigmentation. By using natural compounds such as glycolic acid (derived from sugar cane) and lactic acid (derived from milk), AHAs provide an effective method of skin rejuvenation without the need for harsh physical scrubs. Their ability to enhance the skin's overall look and feel makes them a popular choice in professional skincare treatments and home-care products. Thus, the emphasis on their plant-derived origins and their role in exfoliation makes this description the most accurate among the options provided.
