The world of acids can be overwhelming - there are so many to choose from and they all seem to offer similar benefits. Although at first glance they all seem similar, it is very important to know what each one can help you with. Below we have listed the acids found in cosmetic products and their benefits.
Ascorbic Acid (Vitamin C)
It is probably the most well-known acid on this list, being also known as Vitamin C. Ascorbic acid is also the most researched acid in this field. Being a powerful antioxidant, it helps to slow down the appearance of signs of aging, prevent and heal skin spots caused by exposure to UV rays.
Ascorbic acid is also one of the most effective ingredients used to brighten skin while stimulating collagen production that increases firmness.

Glycolic Acid (AHA)
Glycolic acid is an exfoliator from the AHA family. It is one of the most widely used forms of AHA because it is one of the most researched and effective forms. Compared to other AHAs, glycolic acid has a much lower molecular weight, which means it is more effective at penetrating deep into the skin. This provides a more thorough exfoliation to clear away dead skin cells and help regenerate the skin. In addition, glycolic acid increases the skin's ability to retain moisture, making it one of the most hydrating acids available.

Salicylic Acid (BHA)
Salicylic acid is known as BHA or beta-hydroxy acid. BHAs offer a much deeper form of exfoliation than AHAs. It is an exfoliating agent that opens pores, helps heal wounds and has an anti-inflammatory effect. Being soluble, salicylic acid penetrates the sebum deep into the pores and cleans them. It is recommended for people with oily, mixed or acne skin.
