how long does proactive take to work?

a couple weeks its not going to work that fast

It should work as long as you follow directions for each of the steps involved. As far as time, each case is different.

Sensible diet, good hygiene and low stress should keep acne away. Use great OTC acne products like “Niapads”, “Cetaphil” etc that are simple and easy to use. The most effective product is one that is "simple” to use™. Multi-step treatments are difficult to follow and prolong acne.

For eg - with Niapads (Nicotinamide acne pads) you can cut a piece, wet it with water and place it on the pimple. Active ingredients in Niapads penetrate the skin and provide acne relief. They also are effective in reducing skin hyperpigmentation (acne scars).

Use the gentle scrubbing action for pore cleansing, exfoliation and overall acne relief. Contains Lavender oil – well known moisturizer. Niapads worked for me, try it.
