The control chart of Figure 8-16 shows the results of 89 production runs of a cream containing a nominal 10% benzoyl peroxide measured on consecutive days. Each sample is represented by the mean percent benzoyl peroxide determined from the results of five titrations of different analytical samples of the cream. 

Benzoyl peroxide is available as creams, lotions, gels and washes (2.5, 5 and 10%, and a 4% cream). There is little difference in clinical response to these concentrations in terms of reducing the number of inflammatory lesions, but formulation appears to make a difference. The drying effect of an alcoholic gel base enhances the effectiveness of the active constituent, and it is more effective than a lotion of the same concentration. However, gels have a greater potential for causing skin dryness and irritation than preparations in aqueous bland bases, so water-based preparations may improve compliance. 

Any treatment that thins the stratum corneum increases the permeability of the epidermis and the speed of penetration of AHA. Tretinoin, AHA creams and benzoyl peroxide are all examples of products that allow AHAs to penetrate more deeply. 

EPS may also, in some cases, penetrate too deeply or too quickly if the patient has been using skincare products that thin or remove the stratum corneum. Patients using topical retinoids, AHA creams or benzoyl peroxide should stop using them 2 weeks before EPS to ensure that the stratum corneum regains its normal thickness and function.
