Malic acid is an alpha hydroxy acid (AHA) naturally found in apples and other fruits. It functions as an exfoliant, helping to shed dead skin cells and improve skin texture. Due to its larger molecular size compared to glycolic acid, it penetrates the skin more slowly, potentially leading to less irritation.

What is the difference between malic acid and glycolic acid?
Malic acid has a larger molecular size than glycolic acid, which means it penetrates the skin more slowly and may be less irritating, making it suitable for sensitive skin types.
Can malic acid be used daily?
While generally milder than other AHAs, daily use depends on skin sensitivity and product concentration. It is often recommended to start with less frequent use and gradually increase as tolerated.
