When using glycolic acid
If you want to use glycolic acid, you should first understand its nature. Glycolic acid has a unique effect and is very popular in the field of skin care. The duration of use is related to the efficacy and skin safety, so you should not be careless.
When using glycolic acid for the first time, it should be slow and should be less. Cover the skin needs to be gradually adapted. At the beginning, you can use it every day to check the skin's response. If the skin feels comfortable and does not show any discomfort, such as redness, itching, tingling, etc., you can gradually increase the frequency.
Until the skin has been adapted, it can be increased to once a day. However, this is not a regular rule, and your mileage may vary. For those with delicate skin, use it for a long time, or maintain a low frequency to prevent skin intolerance.
And when using glycolic acid for a long time, it is also related to the desired effect. If you want to exfoliate, make the skin smooth and delicate, use it for a short time, within a few weeks, or it can be effective. However, if you want to improve deep skin diseases, such as light spots and anti-wrinkle, you need to stick to it for a long time, and it will take months or even years to see significant changes.
When using glycolic acid again, stop in time. If the skin is overly sensitive and dry, it must be stopped for a while, and then used as appropriate when the skin returns to normal.
In short, when using glycolic acid for a long time, it is advisable to review the quality of the skin, observe its reaction, take into account the desired effect, and act flexibly to achieve the purpose of maintaining the skin and maintaining the health of the skin.
