DIHYDROXYBIPHENYL

Description

Dihydroxybiphenyl, also known as biphenyl-2,2'-diol, is a synthetic compound with potent antioxidant and antimicrobial properties, making it a valuable ingredient in skincare formulations. This molecule consists of two phenol rings connected by a single bond, allowing it to effectively scavenge free radicals and neutralize oxidative stress in the skin.

In cosmetic applications, dihydroxybiphenyl acts as a preservative and stabilizer, extending the shelf life of products while protecting against bacterial and fungal growth. Its antioxidant capabilities help combat premature aging by neutralizing reactive oxygen species that contribute to collagen breakdown and skin damage.

Research has shown that dihydroxybiphenyl exhibits anti-inflammatory effects, potentially reducing redness and irritation in sensitive skin. It also demonstrates mild skin-lightening properties by inhibiting tyrosinase activity, making it useful in formulations targeting hyperpigmentation and uneven skin tone.

When used in appropriate concentrations, typically between 0.1% to 1%, dihydroxybiphenyl is generally well-tolerated by most skin types. However, as with any active ingredient, patch testing is recommended to ensure individual compatibility. Its efficacy and stability make it a promising component in various skincare products, including serums, creams, and lotions.
