Salicylic Acid Skin Care Benefits

Dec 16,2021 | HISEEK PRETTY

What are the benefits of salicylic acid? Why is it so hot? Let's start with the current state of the industry: an interesting phenomenon is that salicylic acid is highly respected on the Internet, while many cosmetic engineers are trembling with fear and are reluctant to include salicylic acid, an ingredient that is prone to allergy complaints. However, there is no denying that salicylic acid is an ingredient that has many benefits for the skin. The pros or cons depending on the specific product design and the skin type of the user, plus the correct usage. This article will revisit the role of salicylic acid, and how to better use salicylic acid skincare products.

History and Introduction of Salicylic Acid

The salicylic acid raw material is a white powder found in nature in willow bark, aspen leaves, and sweet birch trees, and is a very old-fashioned skin remedy. However, it has little connection with cosmetics and cosmetology. It was not until 1997 when Dr. Kligman published a paper in the American Journal of Dermatologic Surgery mentioning the skincare benefits of salicylic acid that salicylic acid slowly gained some fame. Salicylic acid is also used in the cosmetic industry in large quantities. Similar to AHA (fruit acids), salicylic acid is called BHA, which stands for Beta Hydroxy Acid. Here is an introduction to the effects of salicylic acid.

Benefits of Salicylic Acid 1 - Exfoliating

Salicylic acid, BHA, has lipolytic properties and a larger molecular weight compared to fruit acids, which can lock the action in the superficial layer of keratin and has an exfoliating effect. This is one of the most important roles of salicylic acid.

Salicylic acid benefits 2 - unclogs pores

The lipolytic properties of salicylic acid can penetrate into the stratum corneum and deep pores by fusing with oil to unclog pores. (Is there a little bit of oil-soluble feeling?) When you have cleared the clogged pores and cleared the blackheads, the pores will of course look smaller. Using this salicylic acid, we can find a lot of existing blackheads exporting lotions that are using salicylic acid.

Salicylic acid action 3 - acne removal

Another important aspect of salicylic acid is that salicylic acid can penetrate deep into the pores along with the sebaceous glands that secrete oil, which helps dissolve the old keratin layer inside the pores and improve the blockage of hairs, thus blocking the formation of acne and reducing the size of enlarged pores, but not in reducing sebum secretion and eliminating acne bacteria. Therefore, if a few pimples suddenly appear after using a greasy skincare product, you can consider using an acne product containing salicylic acid for emergency treatment.

Salicylic acid action 4 - Whitening

A study showed that the inhibition of tyrosinase by salicylic acid at a mass concentration of 1 % was 99.2 %. Also, salicylic acid has the ability to exfoliate as described earlier. Therefore, it can also be added to whitening products. However, the whitening ability of salicylic acid cannot be compared with other professional whitening ingredients, so do not think that if you see salicylic acid on the ingredient list, you think the product has whitening ability.

Benefits of Salicylic Acid 5 - Anti-dandruff

Salicylic acid at a concentration of 3% to 6% can be used to exfoliate dandruff, which is essentially a large mass of keratinocytes. Therefore, salicylic acid is also used in anti-dandruff products. However, a concentration of more than 2% is beyond the scope of domestic cosmetic use, and it is possible to find such highly concentrated anti-dandruff products at dermatological offices. This is a point that should not be overlooked in the role of salicylic acid.

A short history of cosmetic applications of salicylic acid.

Salicylic acid has some history in the cosmetic industry, and the following are some of the milestone products.

In 1999, SEEKPRETTY exfoliating glycolic acid tablets, an open shelf product containing BHA, were launched.
Since entering the 21st century, especially in recent years in China, due to the development of network consultation, the use of salicylic acid small brands are more and more, the role and effectiveness of salicylic acid skincare have also been increasingly verified.

Summary and recommendations on the use of salicylic acid and products

1. High concentrations of salicylic acid can be harmful, so the concentration of salicylic acid in cosmetics is limited to 2% in China.
2. Cosmetic hygiene regulations require those cosmetics containing salicylic acid be marked with a warning to determine the safety of long-term use, and that the words "Not for use by children under 3 years of age" be marked on the package. I thought about the possibility of 3-year-olds using salicylic acid, one is to take adult skin care products indiscriminately, the second case is the parents containing adult shampoo containing salicylic acid for children to wash their hair, I hope there are not so rough parents appear.
3. If you suddenly have a few pimples due to a change in skincare products, you can use skin care products containing salicylic acid as first aid. You can try it before going to the doctor for any pimples that are not very serious (of course, you can also use products that contain exfoliating tablets of salicylic acids, such as glycolic acid cotton tablets.) But if you have inflammatory acne, salicylic acid is not going to cure it. You still have to see a doctor for the right thing to do.
If you have severe blackheads on your nose, you can also try products that contain salicylic acid.
When using salicylic acid as an exfoliator, it is not recommended to use it together with other ingredients with exfoliating ability, such as A-alcohol, fruit acids, etc., which will aggravate the damage to the skin.
5. People with sensitive skin are not suitable to use salicylic acid products. Although the effects of salicylic acid create interest
6. When using salicylic acid products, be sure to pay attention to enhancing moisturizing and sun protection.

One last point, use products containing salicylic acid with caution. Please do a skin test before using them!

Salicylic acid has many effects but must pay attention to the irritation do not use indiscriminately.
