What should I pay attention to when brushing acid for the first time? A guide for beginners to brush acid

Acid peeling is a fast-acting skin care method, and it is also effective in clearing acne. Many people want to learn about acid peeling. Generally, they choose to go to a beauty salon for acid peeling, or they can do it at home. What should you pay attention to when doing acid peeling for the first time?

Before acid peeling, you must first understand the tolerance of your skin. It is not recommended for sensitive skin. A acid, fruit acid or salicylic acid are usually used. No matter which acid it is, they all have one thing in common, which is that they can accelerate the exfoliation of dead skin cells, eliminate closed comedones on the skin, reduce acne on the face, and make the skin smoother. It should be noted that it cannot be used frequently. This type of skin care product is more or less irritating. Acid peeling has a phased effect, so be patient. You can see skin improvement after using it for a period of time. In addition, salicylic acid is more fat-soluble than the other two acids, so it is more suitable for improving acne problems on the face.

Fruit acid

Water-soluble acid (mandelic acid is the only fat-soluble fruit acid, which has the dual effects of fruit acid and salicylic acid) mainly promotes the metabolic growth of skin cells, removes old dead skin cells, and promotes melanin metabolism, achieving the effect of brightening the skin tone, improving uneven skin tone, and maintaining delicate and smooth skin. Because it also has a certain moisturizing ability, it is more suitable for dry skin. You must see a dermatologist for a high-concentration fruit acid peel of more than 20%.

Advantages: 1. Compared with other acids, fruit acid is milder. It is the first choice for beginners. 2. Glycolic acid, lactic acid, mandelic acid, lactobionic acid, etc. all belong to the large family of fruit acids, so there is a lot of room for choice. The mildness increases from left to right, that is, lactobionic acid is the mildest and glycolic acid is more irritating.

Disadvantages: 1. Compared with other acids, it is slow to take effect on blackheads and closed pores. 2. It is not effective enough for inflammatory acne.

Salicylic acid

Fat-soluble acid has strong penetration ability and can penetrate into the pores to dissolve oil plugs. It has better treatment effects on blackheads, closed comedones and acne. It also has a certain oil control ability, which can reduce sebum secretion and the growth of acne. Therefore, it is more suitable for oily skin. The concentration added in skin care products shall not exceed 2%.

Advantages: 1. More comprehensive effect, a savior for blackheads, closed comedones and acne. 2. It has a two-way regulating effect on skin keratin. In addition to removing old dead skin cells, long-term use can also increase skin thickness, improve skin barrier function, and promote collagen regeneration. 3. It can also resist inflammation and kill bacteria, and has a certain anti-inflammatory effect on acne.

Disadvantages: 1. Not suitable for dry skin, it will aggravate the dryness of the skin. 2. Slightly more irritating than fruit acid, so it is necessary to replenish water and moisturize.

Azelaic acid

Azelaic acid controls oil, fights inflammation and kills bacteria, improves abnormal keratinization of hair follicles, and has a very good effect on acne. At the same time, it can inhibit the production of melanin, thereby achieving the effect of whitening and lightening spots, and also has a certain effect on lightening acne marks.

Advantages: 1. Azelaic acid has a stronger effect on treating acne. 2. While removing acne, it also has a certain effect on preventing and fading black acne marks.

Disadvantages: 1. Poor solubility and poor skin feel. 2. 15-20% concentration of azelaic acid can remove acne, improve closed comedones, lighten spots, and lighten acne scars, but it may cause burning and itching, so it is not suitable for beginners.

Retinoic acid

It can unclog pores, inhibit skin oil secretion, and penetrate deep into the skin to kill acne bacteria. It is very effective in improving abnormal keratinization of hair follicles and can treat chicken skin, closed comedones and acne. It is a prescription drug and cannot be added to skin care products.

Advantages: 1. It has a long-lasting effect on acne treatment, and generally relapses are rare after it is cured. 2. A low concentration of 0.025% can have a very good effect, and compared with other acids, it works faster and more directly.

Disadvantages: 1. In the early stage of use, it will be accompanied by severe dryness and scaling, which will gradually be alleviated after strengthening moisturizing and sun protection. 2. It is a prescription drug, so you need to consult a professional doctor before use. 3. It is highly photosensitizing, so you need to avoid light before going to bed and apply it on a large area. It must not be used during pregnancy preparation, pregnancy, and breastfeeding, as it is clearly teratogenic.

1. It is not recommended to exfoliate a week before acid brushing

Acid peeling itself can promote the metabolism of the stratum corneum, which is equivalent to exfoliation. If you use additional exfoliating products, it may exceed the skin's tolerance range and cause damage to the skin barrier.

2. Brush acid

Step 1: Cleanse with a mild amino acid cleanser.

Step 2: For those who are applying acid treatment for the first time, you can choose a lotion with a refreshing texture as a base. After the skin has built up tolerance, you can skip the base application step and apply it directly on the face.

Step 3: Take an appropriate amount of acid products for targeted local or large-area application. If the concentration is relatively low, you can also use acid products directly after using toner.

3. After acid brushing

If it is your first time to use acid scrub or your skin is not very tolerant, you can wait for about 20 minutes before washing it off and then apply lotion. For oily skin that is more tolerant, you can apply lotion after using acid scrub and leave it on overnight without washing, the effect will be better.

Pay attention to moisturizing: acid peeling may cause dry and peeling skin, so be sure to use a mild and soothing lotion to moisturize after acid peeling. It is not recommended to use functional products such as whitening and anti-aging during acid peeling.

Pay attention to sun protection: After acid peeling, the skin cannot resist the stimulation of ultraviolet rays, so strict sun protection must be carried out. It is recommended to use hard sun protection methods such as holding a parasol, wearing a mask, wearing sunglasses, and use physical sunscreen when necessary.

There is no exact time limit for this. Everyone's situation is different, their skin type is different, and the length of time will also be different. Under normal circumstances, the effect can be seen in 2 to 3 weeks. Some cases may take 1 month, or even 2-3 months, to see the effect. But no matter what, you can't rush for acid peeling, otherwise it will easily cause a damaged face, and it is best to leave it to a professional organization.
