12% Glycolic Acid Rejuvenation: Efficacy, Ingredients and Usage
Glycolic acid, as an ingredient that has attracted much attention in the field of skin care, plays a significant role in improving skin condition due to its unique chemical properties. 12% Glycolic Acid Rejuvenation, with its suitable concentration ratio, brings many benefits to the skin.

Efficacy
1. ** Improves Skin Quality **: 12% Glycolic Acid Rejuvenation can effectively promote the metabolism of the stratum corneum. It gently loosens the connections between the keratinocytes, making the old stratum corneum easier to fall off, thereby making the skin surface smoother and more delicate. Long-term use can improve the rough and dull skin and significantly improve the overall texture of the skin.
2. ** Brightening complexion **: This skin rejuvenating product has a positive impact on the metabolism of melanin. It can inhibit the activity of tyrosinase, reduce the production of melanin, and accelerate the metabolic excretion of melanin that has been generated, thereby gradually fading pigmentation and even skin tone, giving the skin a natural luster and brightness.
3. ** Firming Skin **: Glycolic acid stimulates the synthesis of collagen in the dermis. With the increase of collagen content, the elastic fibers of the skin are strengthened, which in turn enhances the elasticity of the skin, effectively reduces the production of fine lines and wrinkles, and realizes the effect of firming the skin, so that the skin can be rejuvenated.

Ingredients
1. ** Glycolic acid **: As the core ingredient, 12% glycolic acid concentration has been carefully formulated. This concentration can not only ensure the significant skin rejuvenation effect, but also minimize the irritation to the skin within the range that most skin can tolerate. Glycolic acid molecules are small and can quickly penetrate into the deep layers of the skin, exerting its multiple effects such as promoting keratin metabolism and stimulating collagen production.
2. ** Soothing ingredients **: In order to reduce the irritation that glycolic acid may cause to the skin, soothing ingredients such as aloe vera extract and chamomile extract are usually added to the formula. Aloe vera extract is rich in a variety of polysaccharides and active ingredients, which have good anti-inflammatory and moisturizing effects, and can relieve the discomfort of the skin during the rejuvenation process; chamomile extract contains flavonoids and other substances, which also have excellent soothing and calming skin effects, making the rejuvenation process more gentle.

How to use
1. ** Preparation before use **: Before performing 12% glycolic acid rejuvenation, it is necessary to thoroughly clean the facial skin to remove dirt, oil and cosmetic residues to ensure that the glycolic acid can fully contact the skin and play its role. After cleansing, gently dry the face with a soft towel to avoid excessive friction damage to the skin.
2. ** Skin Rejuvenation Operation **: Take an appropriate amount of 12% glycolic acid rejuvenation product and apply it evenly to the face, avoiding sensitive areas such as eye area and lips. When applying, you can use a cotton pad or a special rejuvenation brush to push it away evenly with gentle movements. The stay time depends on the individual skin tolerance. Generally, it is recommended to stay for 3-5 minutes for the first time. As the skin adapts, it can be gradually extended to 10-15 minutes. During the stay, if the skin experiences a slight tingling sensation, it is normal; if the tingling sensation is strong, it needs to be rinsed off with water immediately.
3. ** Follow-up Care **: After the rejuvenation, rinse the face thoroughly with a lot of water to ensure that the glycolic acid is completely removed. Then, use skin care products with moisturizing and soothing effects, such as moisturizing masks, soothing serums, etc., to replenish moisture to the skin and relieve possible dryness and tightness. At the same time, since the skin after rejuvenation is more sensitive, it is necessary to strictly take sun protection measures to avoid damage to the skin caused by ultraviolet rays. You can choose physical sunscreen and minimize outdoor activities.
