On Glycolic Acid Causes Skin Sensitivity to Sunlight
In modern skin maintenance, the use of glycolic acid has become more and more widespread. However, the public also doubts, it may make the skin sensitive to sunlight? Let's try it out now.

Glycolic acid belongs to the class of fruit acids, with tiny molecules that can quickly penetrate the stratum corneum of the skin. Its main function is to loosen the adhesion between keratinocytes, making old waste keratin easy to remove and promoting skin metabolism. When used properly, it can make the skin smooth and shiny, and reduce fine lines and pigmentation.

However, its use also has the risk of making the skin sensitive to sunlight. After exfoliating with glycolic acid, the stratum corneum of the skin becomes thinner. The stratum corneum is the skin's first barrier to light, and if it is thin, its protective power is weak. Ultraviolet rays in sunlight are easy to invade, and the skin is more easily damaged. Erythema, sunburn, and tanning may appear.

When glycolic acid promotes metabolism, the new skin cells are tender and have poor tolerance to ultraviolet rays. If exposed to sunlight, the DNA in the cells is easily damaged, causing skin inflammation and sensitivity.

And the skin is treated with glycolic acid, and the activity of melanocytes may change. Melanocytes produce melanin to protect against ultraviolet rays. However, at this time or due to changes in the skin microenvironment, melanin production is disordered, and too much melanin is produced, which is not only caused by pigmentation, and may increase skin photosensitivity.

Therefore, those who use glycolic acid for skin care should be careful about sunlight. For daytime use, you must apply sufficient sunscreen. It is better to use both physical sunscreen and chemical sunscreen, and umbrellas, hats, sunglasses, etc. are also indispensable. In this way, you can avoid damage to your skin due to glycolic acid sensitivity to sunlight and enjoy the benefits of glycolic acid skin care.
