Analysis of glycolic acid and underarm odor
In recent times, everyone has paid close attention to the prevention and treatment of body odor, especially underarm odor. The effectiveness of glycolic acid in this field has gradually entered the public's field of vision, and it is worth discussing in detail.

Glycolic acid belongs to the category of α-hydroxy acids, which are often found in sugarcane, sugar beets and other substances. Its molecules contain carboxyl and hydroxyl groups, which have unique chemical properties and are common in various uses for skin care.

Looking at the cause of underarm odor, due to the strong secretion of the sweat glands in the armpits, its excrement is decomposed by bacteria on the surface of the skin, resulting in a special odor. Among these bacteria, most of them are Staphylococcus and Corynebacterium, which use the secretions of the sweat glands as nutrients and cause abnormal odor under the metabolic action

Glycolic acid responds to underarm odor, primarily by regulating the pH of the skin. It is acidic, which can lower the pH of the skin at the armpit and create an environment that is not suitable for the growth of bacteria. Many bacteria grow and multiply, often relying on a neutral and alkaline environment. Glycolic acid changes this environment, which can inhibit bacterial activity, reduce its number, and then slow underarm odor.

Furthermore, glycolic acid has excellent exfoliation. It can loosen the connection between keratinocytes, promote the shedding of old waste keratin, and accelerate the metabolism of the skin. The old waste keratin accumulated in the armpits is easy to hide dirt and provide a breeding ground for bacteria. Glycolic acid removes old waste keratin, cleans the skin, and also reduces the adhesion and reproduction of bacteria, which is of great help to the prevention and treatment of underarm odor.

Another layer, glycolic acid may regulate the secretion of sweat glands. Although the exact mechanism is not fully understood, studies have shown that it may act on the signaling pathway of sweat gland cells, affect the expression of secretion-related proteins, and normalize the secretion of sweat glands, reducing the possibility of underarm odor from the source.

In practical application, products containing glycolic acid, such as underarm special gels, sprays, etc., are convenient to use. However, it should be noted that glycolic acid has a certain irritation, and it should be tested on a small area of skin before use to see if there is any allergy or discomfort. And when used, the frequency and dosage should be controlled according to the product instructions to prevent excessive skin irritation and adverse reactions.

In summary, glycolic acid does have potential in the prevention and treatment of underarm odor. By regulating multiple mechanisms such as skin acid-base, exfoliation and possibly the secretion of sweat glands, a new idea is provided for those who suffer from axillary odor. However, individuals have different reactions to glycolic acid, and the actual effects are different. More research is needed in the future to explore its mechanism of action and the best application, with the hope of developing a better path for the prevention and treatment of axillary odor.
