Glycolic Acid vs AHA
Differentiation between glycolic acid and fruit acid (AHA)
Glycolic acid (Glycolic Acid) and fruit acid (AHA) are often mentioned in various fields such as skin care, but the similarities and differences between the two are not well known.

Glycolic acid is actually a member of the fruit acid family. Its molecular structure is relatively simple, and it is the smallest molecule in the fruit acid category, α-hydroxy acid. This characteristic gives it excellent skin penetration ability, which can quickly reach the deep layer of the skin and play many functions.

Fruit acid (AHA) is a general term for a class of compounds, covering a variety of α-hydroxy acids, glycolic acid is among them. Fruit acid as a whole has the ability to promote the metabolism of the stratum corneum, which can loosen the connection between keratinocytes, make the old waste keratin easier to fall off, and make the skin surface smooth and delicate.

Compared with other fruit acids, glycolic acid has significant effects in improving skin texture and brightening skin tone due to its small molecule characteristics. It can accelerate the metabolism of melanin, fade pigmentation, and make the skin glow. And because it is easy to penetrate, it is relatively high in skin irritation. At the beginning of use, some people with sensitive skin may feel short-term discomfort, such as slight tingling, redness, etc.

The overall application of fruit acid is more extensive. Different fruit acids have different effects due to structural differences. Some fruit acids are excellent in moisturizing and can increase the moisture content of the skin; some focus on anti-inflammatory soothing and relieving skin inflammation.

However, both have a rejuvenating effect, and when used reasonably, they can help the skin regain its vitality. However, users need to choose carefully according to their skin type, starting from a low concentration and gradually adapting to it, in order to avoid skin damage when reaping the benefits of skin beauty.
