What is AHA?
AHA stands for alpha hydroxy acid.
AHAs are water-soluble acids made from sugary fruits.
They help peel away the surface of your skin so that new, more evenly pigmented skin cells may generate and take their place.
After use, you’ll likely notice that your skin is smoother to the touch.
You can find AHA in daily anti-aging products, such as serums, toners, and creams, as well as chemical peels.
There are six types of AHAs commonly used in skincare products.
These include:
- Glycolic acid: derived from sugar cane
- Lactic acid: derived from milk
- Mandelic acid: derived from bitter almonds
- Tartaric acid: derived from grapes
- Malic acid: derived from apples and pears
- Citric acid: derived from citrus fruits
How does AHA exfoliant work?
AHA work by melting the intercellular glue that holds our skin cells together, to help the skin’s natural shedding process.
AHA’s are made up of tiny molecules of water loving and water soluble acids. AHAs are preferred for sun-damaged and dry skin because they exfoliate the skin’s surface and have the added benefit of also improving moisture content.
AHAs are primarily used to exfoliate. They can also help:
- promote collagen and blood flow
- correct discoloration from scars and age spots
- improve appearance of surface lines and wrinkles
- prevent acne breakouts
- brighten your complexion
- increase product absorption
Is AHA suitable for all skin types?
AHAs are primarily used for:
- mild hyperpigmentation like age spots, melasma, and scars
- enlarged pores
- fine lines and surface wrinkles
- uneven skin tone
AHAs are safe for all skin types but you will want to take care if you have extremely dry and sensitive skin.
You may need to gradually work up to daily use to avoid irritating your skin.
How often should you use AHA products?
AHA exfoliants should be applied after cleansing your skin.
Follow with your other skincare products, applying them in order from the lightest texture to the heaviest texture.
Remember to wear sunscreen every single day!
