AHA (Alpha Hydroxy Acid)

They exfoliate and dissolve dead skin cells on the surface of your skin and stimulate the renew of the skin cell process. They help smooth out pigmentation, fine lines, wrinkles, and acne scars while brightening and even out your skin tone. 

glycolic acid

It's the most powerful form of AHA and derived from sugarcane and effective for unblocking pores and controlling sebum production. Ideal for mature skin types.

lactic acid

Derived from milk and sugarcane. It helps to keep the skin moisturized and feeling less dry. Ideal for dry skin types.

mandelic acid

Derived from bitter almonds and contains antibacterial properties. It is a gentler version of AHA(ex. glycolic acid) due to its larger molecule. Helps improve pigmentation, signs of aging, and acne.

tartaric acid

Derived from grapes and tamarinds. You can find it in wine too and has antioxidants.

citric acid

Derived from citrus fruits. Helps adjust pH level and alleviate signs of aging, acne scars and uneven skin tone and texture. Mainly used for its skin lightening and astringent properties. 

BHA (Beta Hydroxy Acid)

Within skincare, the most common of which is salicylic acid! Derived from willow tree bark, wintergreen leaves, and sweet birch bark. As an acid exfoliant, salicylic acid is lipophilic(oil-soluble) and works by softening and dissolving keratin. It easily penetrates deep into the pores and clears out excess sebum and dead skin cells while removing blackheads and whiteheads.

BHA Exfoliators For Acne-Prone Skin Types

Salicylic acid has powerful acne-fighting and anti-inflammatory properties. It helps soothe redness, inflammation and prevent future comedones, making it excellent for acne-prone skin types. 

Chemical Exfoliators For Oily Skin Types

Salicylic acid controls oil production and reduces sebum secretion, helping balance between oil and moisture.

PHA (Polyhydroxy Acid)

PHAs have a larger molecular size than AHAs which makes them penetrate the skin more slowly. It means that it doesn’t exfoliate as hard as AHAs and cause less irritation and redness than AHAs, making it great for all skin types, especially those with sensitive skin.

PHAs exfoliates dead skin cells and excess debris on the surface, resulting in an evener skin tone and texture. It helps reduce fine lines, wrinkles, pigmentation, and acne scarring while hydrating the skin, increasing cell renewal and locking moisture.

lactobionic acid

Derived from plant extract, lactose in cow’s milk. It is a strong humectant and antioxidant that retains moisture within the skin. It increases cellular turnover, leaving the skin plumped and firm. It helps smoothe the skin and reduce the appearance of pigmentation, fine lines, wrinkles, and scarring.

galactose

Found in lactose or milk sugars. It is an energy-providing nutrient that helps aid healing by stimulating collagen syntheses.

gluconic acid 

Naturally occurring in human cells. It helps reduce the appearance of hyperpigmentation by promoting cellular regeneration.
