I'm 40 years old and naturally I had become concerned about fine lines and wrinkles. I had never used serums before and when I was introduced to the 10 step Korean skincare routine by one of my mom's friend, she stressed the importance of double cleansing and using a concentrated serum to minimize and prevent fine lines and wrinkles. She recommended this serum which I bought on the MISSHA USA website. I've been using it for about six months now and I've noticed a difference in my complexion in the morning. My skin looks much more even, firm and supple with no new signs of fine lines or wrinkles. The fine lines I did have have faded away almost completely and the wrinkles on my forehead aren't as deep as they used to be. I also haven't had any breakouts or sensitivity issues.
This serum is lightly scented and light weight however, it has a tacky or sticky consistency, it takes a few minutes for the skin to absorb and because its sticky, its best to pat the product into your skin. I'm not sure how this will work for acne prone/oily skin types and I've read reviews on other cites where people have had sensitivity issues and breakouts so I'll just have to do your research. I DO recommend that you buy this product either from MISSHA USA directly or SOKO GLAM as these are the only two authorized dealers in the US. ( I emailed the company directly to ask because of price difference on Amazon)
