On the superposition of retinol and glycolic acid
Recently, many people have explored the method of skin care. Retinol and glycolic acid have attracted much attention in the way of skin care. However, the method of superposition of the two has different opinions, and it needs to be discussed in detail.

Retinol can help the skin's metabolism, promote collagen production, tighten the skin, fade fine lines, and generate luster. Its effect on improving skin texture and anti-aging is quite significant. Glycolic acid is one of the fruit acids. It has the power of exfoliating, which can make the old keratin on the surface of the skin fall off, make the skin delicate and smooth, and can help the skin absorb other substances. It is also effective in improving dull skin tone, acne and other diseases.

If you want to use retinol and glycolic acid in combination, you should be cautious. Both are irritating. If the skin is already sensitive, it can be superimposed rashly, or cause skin discomfort, such as redness, tingling, peeling, etc. Therefore, when using it for the first time, you need to test the sensitivity first. Take a little retinol and glycolic acid products, apply them behind the ear or on the inside of the arm, and wait for a while to see if there are any adverse reactions.

The order of use should also be paid attention to. Generally speaking, after cleansing at night, it is best to use glycolic acid products first, wait for them to dry a little, and then use retinol. In this way, after exfoliation with glycolic acid, retinol is more easily absorbed by the skin, but this order is not absolute and can be determined according to the individual skin condition.

The dosage is also key. In the initial stage, the dosage should be small, and then gradually increase after the skin adapts. Glycolic acid products can be used once or twice a week, and the same is true for retinol. And during use, if the skin is uncomfortable, you should stop using it immediately. After the skin recovers, try again, or consult a professional.

In short, the superposition of retinol and glycolic acid, if used properly, can achieve good skin care effect, but it needs to be done carefully according to personal skin characteristics, in order to maintain the skin without damaging the health of the skin.
