Mandelic Acid is an alpha hydroxy acid (AHA) derived from bitter almonds. It is a popular ingredient in skincare products due to its exfoliating and skin-renewing properties. Here are its primary function and applications:

1. Exfoliation: Mandelic Acid is a gentle exfoliant that helps to remove dead skin cells from the surface of the skin. It works by breaking down the bonds between dead skin cells, promoting their shedding and revealing fresher, smoother skin underneath.

2. Skin Brightening: Mandelic Acid's exfoliating action can also help to improve skin tone and reduce the appearance of dark spots and hyperpigmentation, resulting in a brighter and more even complexion.

3. Anti-Acne: Due to its antibacterial properties, Mandelic Acid can be effective in combating acne. It helps to unclog pores, reduce the formation of acne-causing bacteria, and reduce inflammation.

Mandelic Acid is commonly used in skincare products in various concentrations, depending on the desired effect and the product's intended use. Some common applications include:

1. Chemical Peels: Mandelic Acid is used in professional chemical peels performed by dermatologists or licensed skincare professionals to address specific skin concerns, such as hyperpigmentation, acne, and aging.

2. Serums and Toners: Mandelic Acid is incorporated into serums and toners for daily use. These products are typically formulated with lower concentrations of Mandelic Acid, making them suitable for regular exfoliation and skin brightening.

3. Spot Treatments: Some products contain higher concentrations of Mandelic Acid and are designed for targeted application to specific areas of concern, such as acne blemishes or dark spots.

4. Anti-Aging Products: Mandelic Acid's exfoliating properties also make it beneficial in anti-aging skincare products, as it helps to improve skin texture and reduce the appearance of fine lines and wrinkles.
