The method of using glycolic acid to rejuvenate the skin at home

Glycolic acid has been favored in recent years because it can effectively improve the skin condition. The following is the method of using glycolic acid to rejuvenate the skin correctly at home:

1. Preparation
1. ** Product selection **: Select glycolic acid rejuvenation products with reliable quality and suitable concentration. For first-time users, it is recommended to choose a lower concentration, such as 5% - 10% of the product, and then gradually try a higher concentration after the skin adapts.
2. ** Skin test **: Before formal use, a skin allergy test is required. Take a small amount of glycolic acid product and apply it behind the ear or inside the arm. Observe for 24-48 hours. If there is no allergic reaction such as redness, swelling, itching, etc., then use it.
3. ** Cleansing Supplies **: Prepare gentle cleansing products for cleansing the skin before rejuvenation to ensure that there is no dirt, oil and cosmetic residues on the surface of the skin.
4. ** Auxiliary Tools **: Prepare clean towels, forceps, small bowls, brushes and other tools. Brushes are used to evenly apply glycolic acid products. Forceps can assist in the treatment of cotton sheets, etc. Small bowls can be used to prepare products (if required).

2. Rejuvenation Steps
1. ** Cleansing the face **: Gently clean the face with gentle cleansing products. After washing with warm water, gently pat dry the facial moisture with a clean towel. Be careful to avoid excessive cleaning, so as not to damage the skin barrier.
2. ** Apply the product **: Use a brush to evenly apply the glycolic acid product to the face, avoiding the eyes, corners of the mouth and damaged skin areas. When applying, the action should be gentle to ensure that the product covers evenly. You can start from the cheeks and apply to the forehead, chin and nose sides in turn.
3. ** Control the residence time **: Determine the residence time according to the product instructions and your own skin tolerance. When using it for the first time, the residence time should be short, such as 2-3 minutes. The follow-up can be appropriately extended to 5-10 minutes as the skin's adaptability enhances. But do not exceed the maximum residence time specified by the product to avoid excessive irritation to the skin.
4. ** Wash the face **: Use warm water to wash the face thoroughly, and wash the glycolic acid product to ensure that there is no residue. During the cleaning process, the action should be gentle and avoid rubbing the skin hard.
5. ** Follow-up care **: After cleaning, gently pat dry the face with a clean towel, and then apply mild moisturizing products in time to replenish moisture for the skin and repair the skin barrier. Avoid the immediate use of highly effective serums, whitening products, etc., so as not to increase the burden on the skin.

III. Precautions
1. ** Frequency Control **: Glycolic acid rejuvenation should not be too frequent. It is recommended 1-2 times a week at the beginning. After the skin adapts, it can be adjusted to 2-3 times a week. Excessive use may lead to thinning and sensitivity of the skin, causing problems such as redness.
2. ** Sunscreen Measures **: After rejuvenation, the skin is more sensitive and its defense ability against ultraviolet rays decreases. Therefore, it is necessary to strengthen sun protection measures. When going out, apply sunscreen, wear a hat, play a parasol, etc., to avoid direct exposure of the skin to the sun and prevent pigmentation.
3. ** Treatment of abnormal reactions **: If the skin experiences severe redness, swelling, tingling, itching and other abnormal reactions during or after rejuvenation, stop using it immediately and rinse with plenty of water in time. If symptoms persist and do not relieve, seek medical attention in time.
