Hi, David. The success in acne treatment is based on three things. Matching the best anti-acne products to the user specific condition, helping the person with acne commit to her/his treatment and monitoring the skin 24/7 to change/improve the routine. MDacne beats curology on all three. It uses computer vison to assess the skin (actually better than any dermatologist /or curology nurse can do), suggests anti acne products (such as benzoyl peroxide) that are much more effective for acne than curology’s “prescription” products. (Azelaic acid, retinoids) and 3; provides 24/7 skin monitoring with its selfie tracker system. The image analysis, AI based system monitors skin improvement and helps motivate the user to commit to her/his treatment which is key to success (N/A in the curology’s solution).
