Avobenzone

Avobenzone is a topical, broad range sunblock. It is widely used in sunscreens as it blocks UVA I, UVA II, and UVB wavelengths, thereby limiting the impact of UV rays on skin. It is also used in cosmetic products to protect other ingredients from deteriorating under the sun.
Since it is hydroquinone-based, it serves many other purposes in skincare. Avobenzone is extremely photostable and is an oil soluble ingredient. It inhibits the discolouration process by interfering with melanocyte physiology and reduces the recurrence rate of black spots due to sunlight or ultraviolet light exposure.
