I began using this item a few months ago in the look for a product to help diminish acne and acne scars. This product was not as harsh on my sensitive skin as some of the other acne products on the market. I have found that it is a good and suitable product for people with acne prone skin that can be used at night and along with your foundation or makeup in the day. I have found that it does help diminish the appearance of scaring over time by drying the skin and it will begin to peel to allow for new fresh skin to appear. As with any product it takes time and is not the fastest acting agent on the market. I find it mid grade compared to others I have used, but it is suitable for daly use without a lot of irritation. If you are looking for a miracle treatment, this is not it, as I said before it takes a lot of time to see the positive effects of this product. Convenience Very convenient for its purpose and ease of use. Side Effects Did not experience a lot of side effects with this product.
