Cosmate®BRC,4-Butylresorcinol is a highly effective skin care additive that effectively inhibits melanin production by acting on tyrosinase in the skin. It can penetrate into deep skin quickly, prevent the formation of melanin, and has obvious effect on whitening and anti-aging.
Cosmate®BRC,4-Butylresorcinol, Butylresorcinol, 4-n-butylresorcinol is a chemical used to treat hyperpigmentation of the epidermis. Hyperpigmentation is believed to be related to the enzyme tyrosinase which produces melanin.It is a highly effective skin care additive that effectively inhibits melanin production by acting on tyrosinase in the skin. It can penetrate into deep skin quickly, prevent the formation of melanin, and has obvious effect on whitening andanti-aging.
Easy to be absorbed by the skin, it can effectively play the role of anti-aging, skin tone conditioning and inhibiting the precipitation of skin pigments in whitening products.By effectively inhibiting tyrosinase, it can prevent the formation of melanin on the skin surface, improve the gloss of the skin,make the skin more uniform, and reduce the deposition of skin pigments. It is widely used in skin care products, skin astringencyproducts and skin repair products, and is easily soluble in oil or water-based formulations.
4-Butylresorcinol is a strong inhibitor of tyrosinase and peroxidase/H2O2, effective as skin lightener and ever-tone for normal and hyper-pigmented skin and even suitable for Melasma treatment.It showed a superior efficacy compared to plant extracts and especially to such products as hydroquinone, arbutin and kojic acid, the most powerful whitening agents on the market, today forbidden or limited for toxicity reasons.4-Butylresorcinol is absolutely safe, its whitening power being combined with a strong protective effect against H2O2-induced DNA damage and an anti-glycation property: a synergic action to improve the skin’s appearence.
4-Butylresorcinol is a synthetic skin-brightening agent known for its potent tyrosinase-inhibiting properties. It is widely used in skincare to address hyperpigmentation, dark spots, and uneven skin tone. Compared to other brightening agents like hydroquinone, 4-Butylresorcinol is considered safer, more stable, and less irritating. Its ability to effectively reduce melanin production and improve skin radiance has made it a popular ingredient in brightening and anti-aging skincare formulations.
Key Functions of 4-Butylresorcinol
*Skin Brightening: Inhibits tyrosinase activity, reducing melanin synthesis and improving the appearance of dark spots and hyperpigmentation.
*Even Skin Tone: Helps fade discoloration and promotes a more uniform complexion.
*Antioxidant Protection: Provides mild antioxidant benefits, helping to combat free radical damage caused by UV exposure and environmental pollutants.
*Anti-Aging Benefits: Reduces the appearance of age spots and promotes a more youthful, radiant complexion.
*Gentle and Effective: Suitable for all skin types, including sensitive skin, with minimal risk of irritation.
4-Butylresorcinol Mechanism of Action
4-Butylresorcinol works by competitively inhibiting tyrosinase, the enzyme responsible for melanin production. By blocking this enzyme, it reduces the formation of melanin, leading to a lighter and more even skin tone. Additionally, its antioxidant properties help neutralize free radicals, protecting the skin from oxidative stress and environmental damage. Its small molecular size allows for effective penetration into the skin, ensuring targeted action on pigmentation issues.
4-Butylresorcinol Advantages & Benefits
*Potent Brightening: Highly effective in reducing hyperpigmentation and dark spots.
*Stable and Safe: More stable than hydroquinone and less likely to cause irritation, making it suitable for long-term use.
*Suitable for All Skin Types: Gentle enough for sensitive skin while effective for all skin tones.
*Multifunctional: Combines brightening, antioxidant, and anti-aging benefits in one ingredient.
*Scientifically Proven: Backed by clinical studies demonstrating its efficacy in improving skin tone and reducing pigmentation.
