Salicylic acid is found in natural willow bark, poplar leaves and sweet birch trees. It is a very old skin medicine. But the real application in skin care products was when Dr. Kligman published a paper in the American Journal of Dermatology Surgery in 1997, mentioning the skin care effects of salicylic acid, began to use it in skin care products on a large scale. Salicylic acid is abbreviated as BHA.
Salicylic acid is very fat-soluble. It can penetrate deep into the pores by fusing with sebum to loosen the plugs, blackheads, and whiteheads that block the pores. These plugs that block the pores are under the action of salicylic acid will automatically emerge from the pores, and the pores will be dredged. Salicylic acid is effective against whiteheads and blackheads.
When the pores are unclogged, the sebum secreted by the skin can be excreted from the body and the food for bacteria is reduced. After the pores are unclogged, oxygen will enter the inside. Most of these bacteria are anaerobic bacteria. When they see oxygen, they will self-destruct and achieve the effect of removing acne.
Salicylic Acid Oil-control Mask also has the effect of inhibiting skin inflammation. The aspirin and methyl salicylic acid that we usually use in large quantities use the characteristics of salicylic acid. The anti-inflammatory properties of salicylic acid can restore the skin in an emergency state to a normal state, avoiding skin cell overreaction, excessive secretion of melanin and other problems.
The Salicylic Acid Oil Control Facial Mask can also inhibit the growth of bacteria and prevent further bacteria from multiplying. However, the bactericidal ability of salicylic acid is not strong, so most of the products based on salicylic acid will add antibacterial ingredients to work synergistically.
Recommendations for the use of salicylic acid
Although salicylic acid is a good ingredient, the highest domestic addition amount is 2%. However, salicylic acid is more irritating and can easily cause skin allergies. For dry and sensitive skin, the mouth may be closed after use. After using up the salicylic acid product, the skin may become dry. Salicylic acid is more suitable for oily skin. For dry skin, it is best to use a small sample first and then use it in large quantities if there is no problem. Products containing salicylic acid can be used as short-term emergency products, and it is not recommended to use them in large quantities for a long time, even if you have a tolerable thick skin. After all, it is an acid product, and if it is used too much, it can still harm the skin.
Salicylic acid has a good effect on blackheads and whiteheads, as well as closed-mouth acne (about closed-mouth acne, I will write an article specifically). The effect is more obvious in the early stage of acne. However, for more serious acne, pustules or even nodules have appeared, there is nothing that can be done. Before using salicylic acid products, you must figure out which stage your acne is in, and you must use it indiscriminately regardless of the situation.
For dry skin and sensitive skin, it is not recommended to try salicylic acid anti-acne products, it may cause the skin to deteriorate further, or even cause acne outbreaks, and the situation is more serious. For products with relatively high salicylic acid content, do not use them all over your face. You can use dots and apply them only on the problematic areas.
When using salicylic acid products, you must pay attention to moisturizing and sun protection. Before using the products of salicylic acid, try it on a small scale first, and use it on a large scale without adverse reactions.
