1. Alpha Hydroxy Acids (AHAs) 

2. Beta Hydroxy Acids (BHAs)

Above mentioned acids serve different purposes for the skin type with specific concerns.

 Different Types of Acids and Their Benefits

1. Alpha Hydroxy Acids (AHAs)

AHAs are derived from fruits, milk or plants, water soluble acids that primarily work on the skin surface by breaking down the “glue” that holds dead skin cells together. These acids shed them and reveal fresh, smooth skin underneath. Here are the most common AHAs used in skincare are

a.      Glycolic Acid

It is derived from sugarcane, and it is one of the popular AHA’s with small molecular structure that allows deep penetration into the skin and exfoliate effectively. Glycolic acid helps treat skin aging signs, fine lines and wrinkles along with skin brightening and improve texture.

b.     Lactic Acid

Lactic acid is made from milk or plant-based sources like fruits and gentle. It is suitable for sensitive skin. Exfoliates the skin, keeps skin hydrated with even skin tone making the skin devoid of dryness and dullness.

 2. Beta Hydroxy Acid (BHA)

BHAs are oil soluble ingredients unlike the AHA’s which are water soluble. Oil soluble nature makes their penetration deep into the pores to remove excess oil, dirt and debris. These are best suitable for individuals with oily or acne prone skin. Salicylic acid is the most common BHA and let’s know about it.

a.      Salicylic Acid – It has anti-inflammatory and antibacterial properties that help to treat acne, blackheads and whiteheads. As it is oil soluble, it penetrates to the pores to exfoliate inside and unclog the pores to reduce breakouts.

1. Ascorbic Acid (Vitamin C)

It is commonly termed vitamin C, one of the best antioxidants in skincare. It inhibits the enzyme tyrosinase, the enzyme responsible for production of melanin pigment. Inhibiting melanin helps to reduce dark spots, age spots and uneven skin tone. It can neutralize the free radicals that damage skin cells and prevent premature skin aging. Also, it enhances production of collagen, the protein responsible for keeping the skin firm and youthful.

Retinoic acid, tretinoin is a powerful derivative of vitamin A that serves a variety of skin concerns from acne to aging. Retinoic acid speeds cell turnover, preventing clogged pores and acne breakouts. Increases collagen production, which can accelerate skin’s natural exfoliation process. Diminishes fine lines and wrinkles and appearance of pores with improved skin texture.

Usually, Retinoic acid is suggested to apply during the night as it is sensitive to sunlight.

5. Stearic Acid

Unlike other acids listed above, Stearic acid is a fatty acid found in plants and animal fats, used as an emulsifier in skincare.
