product description

Product Introduction

4-butylresorcinol is one of the stable derivatives of Resorcinol (1,3 dihydroxybenzene), which is also a tyrosinase inhibitor thanks to a similar structure (free OH groups in specific positions of the aromatic ring). Blocking one of the crucial enzymes in the melanin synthesis cascade lessens hyperpigmentation, blotches, and freckles.

Incorporated in skin care applications, 4-Butylresorcinol significantly reduces UV-induced forearm pigmentation. Preventing melanin production, it is a powerful skin-whitening agent that is much more stable and effective than conventional lightning ingredients. 4-Butylresorcinol rapidly penetrates deeper layers of the skin, exposing a uniform, brighter, and radiant complexion.

4-Butylresorcinol is a compound valued in skincare for its skin-lightening properties. It inhibits the activity of tyrosinase, an enzyme involved in melanin production, thus reducing the appearance of hyperpigmentation, dark spots, and uneven skin tone. Additionally, it acts as an antioxidant, protecting the skin from oxidative stress and environmental damage. Commonly found in topical formulations such as serums, creams, and spot treatments, 4-Butylresorcinol is suitable for addressing various pigmentation concerns, including melasma and sun-induced discoloration. Overall, this ingredient helps in achieving a brighter and more radiant complexion.

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 appearance. 4-Butylresorcinol was added to both liquid and solid soap formulations and showed its efficacy as skin lightening after only a few weeks of treatment.

4-Butylresorcinol is one of the best ingredients for treating hyperpigmentation and facilitating skin-lightening in the cosmetic industry. It even works wonders for melasma treatment which is the condition of dark patches appearing on the face due to hormonal changes during pregnancy. Further, this ingredient is a potent antioxidant and protects the skin against damaging environmental stressors such as dirt and pollution. 4-Butylresorcinol is better than hydroquinone - another skin-lightening agent in the market - as it is more effective. It is also known by its other names such as rucinol and 4-butylbenzene-1,3-diol. The chemical formula of 4-Butylresorcinol is C10H14O2 and it appears in the form of a light beige powder.

4-Butylresorcinol is a whitening and skin lightening agent with unique characteristics in terms of efficacy and safety on the skin. 4-Butylresorcinol shows 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.
