50 Concentration Glycolic Acid Home Rejuvenation Guide
Preparations
All 50 Concentration Glycolic Acid Home Rejuvenation Techniques must be carefully prepared first. The first thing you need is glycolic acid rejuvenation products, and the concentration must be accurate to 50. For the second preparation of cleansing milk, you need to choose a mild and non-irritating one to purify the dirt and oil on the surface of the skin. A neutralizing solution should also be prepared to stop the action of glycolic acid in time to prevent skin damage. You also need to prepare several cold compresses or ice packs to relieve the discomfort of the skin after rejuvenation. Also prepare a clean and soft towel, cotton swab and other auxiliary products.

Operation steps
1. ** Cleansing and Skin Cleansing **: Before operation, moisturize the face with warm water, take an appropriate amount of gentle cleansing milk in the palm of your hand, gently rub and lather, gently massage the facial skin, focusing on the T-zone, both sides of the nose and other areas with strong oil secretion. After about one minute, wash thoroughly with warm water, and gently dry the face with a dry towel to make the skin dry and clean.
2. ** Skin Test **: Select a small piece of skin behind the ear or inside the arm, dip a cotton swab in a small amount of glycolic acid rejuvenation product, and apply it evenly to the test area, with an area about the size of a coin. Wait for 15-20 minutes, and observe the test area closely during this period. If there is no abnormal reaction such as redness, swelling, itching, and tingling, the whole face can be rejuvenated.
3. ** Skin Rejuvenation Application **: Take an appropriate amount of 50-concentration glycolic acid rejuvenation product, and apply it evenly to the facial skin with a brush or cotton swab in the order of forehead, cheeks, chin, and nose wings. Pay attention to avoid sensitive areas such as eyes and lips. When applying, the action should be gentle to ensure that the product is evenly covered and no omissions should be made.
4. ** Timing of action **: After the product is applied, start timing immediately. The time for 50-concentration glycolic acid to act on the face is usually 3-5 minutes. If the skin feels unbearable tingling during this period, the operation should be terminated immediately.
5. ** Neutralization treatment **: After the timing is over, quickly apply the neutralizing liquid evenly to the face, and gently massage to make the neutralizing liquid fully react with glycolic acid to stop its effect on the skin. After about 1-2 minutes of massage, rinse the face thoroughly with a lot of water to ensure that the neutralizing liquid and glycolic acid residues are cleaned.
6. ** Cold compress to soothe **: After rinsing, take a cold compress or an ice pack and apply it to the face for about 15-20 minutes. This step can effectively reduce skin redness, swelling, fever and other uncomfortable symptoms and soothe the skin.

Follow-up care
1. ** Moisturizing care **: After the cold compress is over, gently dry the facial moisture with a dry towel, take an appropriate amount of mild moisturizing cream or lotion, apply it evenly to the face, gently massage until fully absorbed, replenish moisture and nutrients for the skin, lock in skin moisture, and promote skin repair.
2. ** Sunscreen measures **: After rejuvenation, the skin is extremely sensitive and has a reduced ability to resist ultraviolet rays. Therefore, when you go out later, be sure to do a good job of sun protection. You can apply mild sunscreen products, or wear a wide-brimmed sun hat, use a parasol and other physical sunscreen methods to avoid direct exposure of the skin to the sun to prevent pigmentation and sunburn.
3. ** Diet Note **: Within a few days after skin rejuvenation, the diet should be light, and eat more fruits and vegetables rich in vitamin C and vitamin E, such as oranges, lemons, kiwis, nuts, etc. These foods help the skin resist oxidation and repair. Avoid spicy, greasy, irritating foods, so as not to irritate the skin and affect recovery.

The above steps and precautions must be strictly followed when using 50-concentration glycolic acid home rejuvenation method. If there are doubts about the operation or abnormal skin conditions, a professional should be consulted in time.
