On the feasibility of using glycolic acid and mandelic acid together
There are various methods for skin care, and acid skin care methods are gradually emerging. Among them, glycolic acid and mandelic acid have their own effects, but whether they can be used together is a matter of concern to many beauty lovers.

Glycolic acid is an alpha-hydroxy acid with small molecules and strong penetrating power into the skin. It can reach the deep layers of the skin and quickly dissolve the "adhesive" between keratinocytes, causing the aging stratum corneum to fall off, and the surface of the skin to be renewed, showing a smooth and smooth state. And it can stimulate collagen regeneration, which is also effective in reducing wrinkles and improving skin quality.

Mandelic acid is also a family of α-hydroxy acids, but its molecular structure is slightly larger than that of glycolic acid. This acid is mild and antibacterial, can inhibit Propionibacterium acne, and is beneficial to acne and acne. It can also loosen the exfoliation, help the skin's metabolism, and make the skin delicate and shiny.

As for whether the two can be used together, it should be carefully considered. Both have the effect of exfoliation. If used together, the power of exfoliation may increase sharply. If the skin is delicate, it may cause skin discomfort if used together rashly, such as redness, tingling, desquamation, etc. However, if the skin is well tolerated and used properly, it may also have a synergistic effect.

If you want to use glycolic acid and mandelic acid together, you should first check the skin's tolerance. You can use one of them alone first, such as using glycolic acid first. Since the low concentration, gradually increase the concentration and frequency of use to observe the skin's reaction. If the skin adapts well, then add mandelic acid. When using it for the first time, the concentration should be low and the use interval should be long, such as once every three days, when the skin adapts, then gradually adjust it.

And when using, the protection method should not be ignored. Strict sun protection is required during the day, because the skin is more sensitive to ultraviolet rays after exfoliation. If there is no protection, it is easy to cause pigmentation. You should also pay attention to moisturizing. The combination of the two may cause the skin to lose moisture, so you must always apply a moisturizing mask and apply moisturizing skin care products to maintain the balance of skin water and oil.

In summary, although glycolic acid and mandelic acid may be used together, it is necessary to be cautious. According to your own skin condition, use them reasonably to achieve the best state of skin care and avoid the risk of skin damage.
