All products tested and are the highest in anti-acne properties I have ever seen. Here is a breakdown:
COSRX Real Therapy Lotion: This product is great, but it is very expensive and has limited applications. It has very little active ingredients, so it may be a good idea to use a moisturizer for the rest of the week and then add this one as a last step if you are sensitive.
Dermabrasion: This is my favorite product against acne. It is very gentle and does not irritate the skin. It is also very effective, so it is my best bet.
Vita-3: This is the only active ingredient I have used and the only one that I would recommend. I would recommend using this for all types of acne, since it doesn't have any side effects. I used it for a few days and I noticed that it worked quite well on my acne, so I have no complaints about its effectiveness. The only problem I have with this product is that I can't see any benefit from using it alone, but I also don't think that using it with a prescription cream would be much better. The main benefit I find is that it helps my acne go down very fast, which I find a good side effect of any acne cream.
