Can kojic acid and salicylic acid be used together?

Kojic acid can inhibit the synthesis of tyrosinase, and thus can strongly inhibit the formation of skin melanin. It is safe and non-toxic and will not produce sequelae of white spots. Therefore, kojic acid has been added to lotions, facial masks, lotions, and skin creams. So, let’s talk about whether kojic acid and salicylic acid can be used together? What are their main effects?

Can kojic acid and salicylic acid be used together?

Kojic acid and salicylic acid cannot be used together. Salicylic acid and other acids, as well as niacinamide and retinol, cannot be used together. When mixed with acids, the acid concentration will rise suddenly, which will have a great burden on the skin, damage the skin barrier, and may even cause acne breakouts; niacin, the raw material ingredient of niacinamide, can cause skin irritation, and acids are also irritating, which can cause discomfort; retinol must be converted into retinol acid to be useful. If it is superimposed with acid products with a lower pH value, it will affect the effect of retinol and will also irritate the skin.

What is Kojic Acid

Kojic acid is a melanin-specific inhibitor. After entering the skin cells, it can complex with the copper ions in the cells, change the three-dimensional structure of tyrosinase, prevent the activation of tyrosinase, and thus inhibit the formation of melanin. Kojic acid-based whitening actives have better tyrosinase inhibition effects than other whitening actives. It does not act on other biological enzymes in the cells and has no toxic effect on the cells. At the same time, it can enter the intercellular matrix and form intercellular colloid, which plays a role in retaining water and increasing skin elasticity.

What is Salicylic Acid

Salicylic acid is an organic acid, and salicylic acid is currently considered to be fat-soluble, so salicylic acid has a more obvious effect on women's skin. Salicylic acid removes hyperkeratotic hair follicles, thereby unclogging pores. In addition, salicylic acid can damage the liver and kidneys. Due to its high irritation, continuous use may have counterproductive effects. Therefore, when using salicylic acid, you must be careful to differentiate skin types and take targeted, appropriate concentrations of salicylic acid to avoid further aggravation of skin symptoms.

How to correctly brush acid

After cleansing, first do basic hydration and moisturizing, then apply it on the face with cotton pads or smears according to different products, and wash it off with clean water after 10-15 minutes. You can gradually increase the time from 10-15 minutes to 30 minutes, etc., but try not to leave it overnight. You can do partial acid scrubbing or full-face acid scrubbing.
