A: Benzac products are commercially available in different concentrations, such as 2.5%, 5%, and 10%. The percentage refers to the concentration of the active ingredient, benzoyl peroxide, present in the formulation.
Q: Is it okay to use Benzac if I have very sensitive skin?
A: Regulatory warnings advise against using the product on skin that is very sensitive. Regulatory labeling includes a warning advising testing the product on a small area first to assess the skin's reaction.
Q: Can I apply makeup shortly after using Benzac?
A: Official patient instructions generally advise avoiding the application of cosmetics or other skin products to the treated area unless otherwise directed. This is noted to avoid potential interference or increased skin irritation.

A: Yes, regulatory warnings indicate that the use of a sunscreen is necessary when using Benzac. This caution is due to the potential for the product to increase the skin's sensitivity to sun exposure.
Q: Is the tingling sensation I feel after application a sign that Benzac is working?
A: While common adverse reactions include a burning sensation or stinging, regulatory labels do not interpret these feelings as a sign of the product's efficacy. These sensations are usually related to temporary skin irritation.
Q: What kind of skin care products should I avoid while using Benzac?
A: Official patient instructions advise avoiding other topical preparations that may increase skin irritation or dryness. This list includes abrasive soaps, cleansers, and products that contain alcohol.
