What is Hydroquinone and Why Does Opalya Avoid It?
Hydroquinone is an organic compound that appears as a white crystal. It’s known for its antiseptic and oxidizing properties and has been used in various industrial applications, such as photographic development and rubber production. In cosmetics, hydroquinone is popular as an active ingredient in skin-lightening products due to its ability to inhibit the enzyme tyrosinase, which is involved in melanin production. This helps lighten areas of hyperpigmentation like brown spots and acne scars.
When applied topically, hydroquinone penetrates the skin and normalizes excessive melanin production. While it is effective and often regarded as the “gold standard” for treating hyperpigmentation, concerns have arisen regarding its safety, especially with prolonged use. Common side effects include skin irritation and redness, but there are also more serious risks, such as exogenous ochronosis, which can cause irreversible darkening of the skin.
Recognizing these concerns, Opalya has opted to develop lightening milks that do not contain hydroquinone, focusing instead on safe alternatives like fruit acids and plant extracts. This commitment reflects a broader priority for consumer safety and skin health, providing effective options for treating hyperpigmentation without the associated risks of hydroquinone.
