Introduction to AHA

AHA stands for "Alpha Hydroxy Acid," an organic acid used in cosmetics and skincare to exfoliate dead skin cells, brighten, and improve skin condition.

There are various types of AHAs, such as glycolic acid, lactic acid, citric acid, and many others. Each type of AHA has its characteristics and different effects on the skin. However, they all have the ability to exfoliate dead skin cells, leaving the skin smoother and brighter. Among the most common AHAs are Glycolic Acid and Lactic Acid, known for their mildness and minimal skin irritation.

Functions of AHA

Exfoliation:

AHA softens the outer layer of the skin and helps eliminate dead skin cells. This results in softer skin, reduces roughness, and allows the new skin layer to emerge. You can use chemical exfoliants with AHA at a concentration of 10% or higher, with a pH level of 3-4. Since chemical exfoliants are acidic, they are sensitive to sunlight. Therefore, it's recommended to apply them in the evening and use sunscreen the next morning to remove any dead cells pushed to the surface overnight.

Brightening:

AHA helps fade scars, freckles, dark spots, and uneven skin tone. By removing the layer of dead skin cells and stimulating the regeneration of new cells, the skin appears brighter and smoother.

Improving Skin Elasticity:

AHA stimulates the production of collagen and elastin, crucial components for good skin elasticity. Enhancing the presence of collagen and elastin helps the skin become firmer, reducing the appearance of wrinkles.

Minimizing Pores:

AHA cleans and unclogs pores, making them appear smaller and reducing the chances of blockages, preventing acne.

Balancing Skin:

AHA has the ability to balance oil production and control excess oil. This can prevent excessive oiliness and reduce the risk of acne.

Enhancing Product Absorption:

By removing the layer of dead skin cells on the surface, AHA helps subsequent skincare products penetrate deeper into the skin, increasing the effectiveness of the regimen.

However, using AHA requires caution, especially for sensitive skin. Excessive or improper use can lead to skin irritation.

Choosing the Right AHA Concentration for Your Skin Type

AHA is a chemical compound commonly used in skincare products to remove dead skin cells and improve skin conditions. However, choosing AHA-containing products with the appropriate concentration for each skin type should depend on your skin's condition and tolerance. Here are some suggestions:

Sensitive and Dry Skin:

If you have sensitive or dry skin, choose AHA-containing products with a low concentration, around 5% to 7%. This helps avoid excessive impact on the skin and reduces the risk of irritation.

Combination and Normal Skin:

Combination and normal skin can usually tolerate a medium concentration of AHA, ranging from 8% to 10%. This helps improve skin condition without causing too much impact if your skin is not overly sensitive.

Oily and Acne-Prone Skin:

For oily or acne-prone skin, you can use products containing AHA with a higher concentration, from 10% to 15%. AHA helps clean pores and remove dead skin cells, controlling acne and oil.

Skin Accustomed to AHA:

If your skin is accustomed to using AHA and shows minimal adverse effects, you may consider using products with a higher concentration. However, monitor your skin's condition and reduce usage if there are signs of irritation.
