What you need to know about this controversial skincare ingredient

However long term use of Hydroquinone was faintly associated with a skin reaction where darkening occurs where it’s applied called Exogenous Ochronosis where the skin thickens and turns bluis-grey.

Over-the-counter Hydroquinone products usually can contain up to 2% (the most effective over-the-counter amount) for more stubborn hyper pigmentation or dark spots, 4% concentrations of Hydroquinone are usually prescibed.

However if you decide to go with Hydroquinone, note that minimal air exposure is required as it degrades the potency. It should also come packaged in an opaque container.

To also get the best out of Hydroquinone, reduce sun exposure- as with other skin lightening ingredients- to the barest minimum and make sure to wear sunscreen.

There are however alternatives to Hydroquinone as there are natural extracts you can use instead. Do well to consult a physician or dermatologist for this.
