What is the reasonable % of hydroquinone in a skin cream?
I would say 4% because a product containing that much can be bought over the counter.
Reply:No higher than 3 - 4 %
Reply:Start with like 2% to make sure you dont have a reaction to it. then go up from there. Good luck
Reply:hydroquinone. Substance that is known to successfully reduce the intensity of freckles, melasma, and general brown patching by inhibiting melanin production. For continued and increased effectiveness it must be used long term. Unprotected sun exposure should be avoided, because it reverses the effect of hydroquinone by increasing melanin production. Occasionally, at higher concentrations, persons with a darker skin type will experience increased pigmentation, but this is rare. It can cause mild skin irritation and there is the possibility of an allergic reaction. Hydroquinone in 1% to 2% concentrations is available in over-the-counter products; 4% concentrations are available by prescription only (Source: American Journal of Clinical Dermatology, September-October 2000, pages 261–268).
Reply:Most over-the-counter products contain 2% while clinical (medical) formulations are 4%.





I wouldn't use anything higher than 4% and there's some evidence showing that even that small amount is not healthy and/or can produce even darker pigmentation in the long run.





If using more than 2% you might want to check in with a dermatologist or aesthetican to monitor your progress.





Good luck!
