There are many whitening ingredients, such as arbutin, nicotinamide and 377, which are familiar to everyone. Today, let's look at a member of the same family as 377, but the effect is better than 377, which is 4-butyl resorcinol.

4-Butyl resorcinol. It has a strong ability to inhibit tyrosinase activity. It inhibits the production of melanin from the basal layer and has a very good whitening effect.

Specific effects are as follows:

Whiten skin

It can effectively inhibit the activity of tyrosinase in the skin, block the formation of melanin, accelerate the decomposition and excretion of melanin through the direct combination of itself and tyrosinase, thus reducing the deposition of skin pigment and achieving the whitening effect.

Fade acne mark



Because of the super whitening effect of 4-butyl resorcinol, persistent use can dilute the acne marks caused by melanin precipitation.

freckle removing

4-Butyl resorcinol is a small molecule compound, which can penetrate into the bottom layer of the skin, and can play the role of lightening spots if it is used for a long time.

In addition, it also has certain therapeutic effects on senile plaques. A related research team organized clinical tests on 14 elderly volunteers (55~60 years old, female). Use the preparation containing 0.3% 4-butyl resorcinol, 0.3% hexyl resorcinol and 0.5% phenylethyl resorcinol twice a day to treat senile plaques.

After 8 weeks, 4-butyl resorcinol significantly reduced senile plaques, and the effect was significantly better than hexyl resorcinol and phenylethyl resorcinol.

Another thing to note is that the use of this ingredient needs to establish tolerance, because some people have skin intolerance to 4-butyl resorcinol, which may cause redness, swelling and pain on the face.

Finally, I'd like to chat with you. Regardless of the price of skin care products, whether they are domestic or imported, only those that are suitable for me are the best.
