Hello niniko111, using any skin care products that are harsh to skin is not actually advisable. Washing alone twice a day with mild soap can help in getting rid of acne. Natural products are also helpful since it does not contain substances that can irritate the skin. If you are familiar with Manuka honey, you can try applying it to your skin, it's safe and natural. If you have time, you can read this blog about the Manuka honey http://goo.gl/CX7sPZ .
Niniko: Burning after applying moisturizer is a common reaction, and also very common in the early weeks of the Reg as your skin is adjusting to the treatment, what they call the "hardening phase". As long as you're not allergic to the products the burning will eventually go away.
