The Acne Pack of 2 Cleansers and 1 sun screen should easily last you 4 months.
With acne treatment less is more when it comes to non prescription products.
Beta Cleanser: A salicylic acid 2% + natural fruit enzyme wash. Not as strong and drying as benzoyl peroxide, yet has deeper oil dissolve then typical 1% sal acid washes. Use up to twice a day.
Solar Defense: When the acne is over, worry about scarring begins. Prevent it now with Elavo sun screen that is designed for acne prone skin. Other sunscreens can undo the hard work of your regimen by being too thick, and plugging your pores. Solar defense will feel like silk on your skin: plenty of UV protection, yet plenty of breathing for your skin cells.
