On the combination of glycolic acid and vitamin C
Fuglycolic acid and vitamin C, both are wonderful skin care products, but whether they can be used together, there are different opinions, and it needs to be explored in detail.

Glycolic acid belongs to the class of fruit acids and has excellent exfoliation ability. It can loosen the adhesion between keratinocytes, make old keratin fall off, and make the skin surface smoother and more delicate. And it can stimulate the synthesis of collagen in the dermis, enhance skin elasticity, improve fine lines and wrinkles, and make the skin glow.

Vitamin C is also a leader in the skin care industry. It has powerful antioxidant properties, can resist free radical damage to the skin, and delay skin aging. It can inhibit tyrosinase activity, reduce melanin production, and achieve the effect of whitening light spots. And it helps collagen synthesis and maintains the integrity of skin structure.

As to whether the two can be used together, it needs to be treated with caution. Glycolic acid is acidic and can reduce the pH value of the skin, while vitamin C is more stable in an acidic environment. Theoretically speaking, the combination of the two may synergistically synergize and play a greater role in whitening and anti-aging.

However, glycolic acid itself has a certain irritation to the skin, and if the concentration of vitamin C is too high, it may also cause skin discomfort. The combination of the two may cause irritation to be superimposed, causing allergic reactions such as redness, swelling, tingling, and itching in those with poor skin tolerance.

Therefore, if you want to combine glycolic acid with vitamin C, it is advisable to do a trial test on the local skin first. And you should start with a low-concentration product, gradually increase the concentration and frequency of use, to see how the skin adapts. If there is any discomfort to the skin during use, stop using it immediately and consult a professional dermatologist.

In short, the combination of glycolic acid and vitamin C has both advantages and disadvantages. Users need to weigh the advantages and disadvantages according to their own skin type, and be cautious in order to seek the good effect of skin care and avoid skin damage.
