If you are currently tolerating your regimen well and it doesn't include hydroquinone, you can continue to use these products. However, do not use any other acids (vitamin c, alpha hydroxy, benzoyl peroxides, retinoids) with this cream until your skin gets familiar with it (this process can take up to two weeks).
When you are ready to incorporate personal products, add one new cosmetic product at a time per week.
The Spot Cream should be the first thing you apply to your skin after cleansing your face. Wait 1-5 minutes for The Spot Cream to dry before applying other products (don’t forget sunblock).
