Comparison of Benzoyl Peroxide, Salicylic Acid and Glycolic Acid

Introduction
In the field of skin care, many chemicals are widely used to achieve various skin improvement purposes. Among them, benzoyl peroxide (Benzoyl Peroxide), salicylic acid (Salicylic Acid) and glycolic acid (Glycolic Acid) have attracted much attention. These three have their own characteristics, and there are differences in skin care efficacy and applicable skin types. The following will be compared in detail.

Benzoyl peroxide
Benzoyl peroxide
Benzoyl peroxide is mainly used to treat acne. Its mechanism of action is to slowly release new ecological oxygen and benzoic acid, which have strong oxidative properties and can kill Propionibacterium acne, which is a key factor in causing acne. At the same time, it can thin the stratum corneum of the skin, which is conducive to drug penetration and skin metabolism. However, it also has drawbacks and is highly irritating to the skin. Some people will experience dry, desquamation, redness and other phenomena after use. People with sensitive skin need to use it with caution. It is advisable to start with a low concentration when using, gradually increase the dosage and frequency, and moisturize the skin during use.

Salicylic acid
Salicylic acid is a fat-soluble organic acid that can penetrate deep into the pores, dissolve oil, and clean the sebum that clogs the pores. It has good effect on acne and acne. It also has anti-inflammatory properties, which can relieve the inflammatory response caused by acne. In addition, salicylic acid can promote the metabolism of the stratum corneum and improve the rough and dull condition of the skin. However, salicylic acid is also irritating, and high-concentration use may cause skin burns and peeling. Skin sensitivity tests are required before use. Low-concentration products are relatively mild and suitable for most skin types. However, caution is still required when using sensitive skin, and sun protection should be paid attention to after use.

Glycolic acid
Glycolic acid is the smallest molecular weight of fruit acids, with strong permeability. It can quickly penetrate the surface of the skin, promote the renewal of stratum corneum cells, accelerate the exfoliation of old waste keratin, make the skin smooth and delicate, and improve uneven skin tone. It can also stimulate collagen production, enhance skin elasticity, and reduce the production of wrinkles. However, glycolic acid is also irritating to the skin, and there may be slight tingling and redness in the early stage of use. When using, it is necessary to build skin tolerance, starting from low concentration and low frequency, and strict sun protection is required during use, because it will make the skin more sensitive to ultraviolet rays.

Comparison of applicable skin types
1. ** Benzoyl peroxide **: Mainly suitable for oily and acne skin, it can effectively control oil secretion and kill Propionibacterium acne. However, it is easy to cause discomfort when used on sensitive skin.
2. ** Salicylic acid **: It is more suitable for oily and mixed skin, which can not only clean pores and oil, but also anti-inflammatory. Sensitive skin needs to be tried with caution.
3. ** Glycolic acid **: The use of dry and normal skin can improve roughness and aging problems. However, the use of sensitive skin needs to be extra careful, and the local trial should be carried out first.

Conclusion
Benzoyl peroxide, salicylic acid and glycolic acid have their own advantages in the field of skin care. Benzoyl peroxide focuses on acne treatment; salicylic acid has a significant effect on cleaning pores and anti-inflammation; glycolic acid performs well in improving skin aging and roughness. When choosing, you should choose suitable products carefully according to your own skin type and skin problems. If necessary, you can consult a professional dermatologist for advice to achieve the best skin care effect and avoid skin damage.
