Is it okay to use a kojic acid face wash and afterwards, use retinol mixed with hydroquinone at night?

Dear kaedy:  This is in fact a great regimen for lightening the skin and evening out the skin tone. Glycolic acid, vitamin C, and Niacinamide are also effective for this.  Higher concentrations of Retinol and Hydroquinone are obviously going to be more effective.  All the best,  Dr. Clark
