I have used (& previously recommended) hydroquinone. But it's highly toxic. However, I've now learned there are FAR better products that are not harmful. So, I no longer recommend hydroquinone.
And it sounds like it is too strong for your skin. SO PLEASE STOP USING IT ASAP! Instead, look for quality natural, non-toxic lightening products with B3 niacinamide etc.
Or you can buy pure B3 Niacinamide (i.e. from www.newdirections.com.au) and add a VERY SMALL sprinkle to a carrier oil (like grapeseed oil) and apply it to your skin evenly. Just don't get it near your lips or it will lighten them!
Buy a reputable product with a safe amount of B3. It's best not to use this alone, it is a strong product & could damage your skin otherwise. And there are other quality natural lightening products out there, so try those instead and throw away the hydroquinone!!
~ Peace ~
