Hello Elsie. Yes, there are stronger prescription formulations than 4% hydroquinone and you can see the excellent results we get with our higher strength (up to 8%) product by clicking on the link to our website below.
Anything over 4% is a compounded product, which means the formulation is determined by the medical office and the compounding pharmacy. In addition to using up to 8% HQ, we do not include Retin A in our formulation because it irritates many of our patients. Because it is dispensed in a liquid form, it penetrates more easily and yields better results.
We have offices in Torrance and Orange, CA and would be happy to meet with you for a free consultation to discuss your condition.
