This is possibly the best serum I have ever used thus far… I have combination skin which is quite sensitive and prone to break outs… I have some blemishes from acne scaring which I have been too afraid to treat topically until now! I have noticed a marked difference in not only blemishes from scaring but also an overall even skin tone. I love this product used in conjunction with the day moisturiser they recommend. Do yourself a favour and give this one a try!
