Review title is Great for Acne, Fresh And Clean Feel. [SEP] I received NOTS brand 28 Day Remedy on June 12th as a promotional item from the company. This product is available with Amazon Prime Delivery so it came in about 3 days. This is nice because I don't like being without my skincare for more than a few days.<br /><br />I have been using 28 Day Remedy twice a day for 10 days now. I have had serious acne problems in the past and usually I would have to use multiple acne care products to keep my skin clear. For me this serum by itself was enough to keep my acne problems away. I did however incorporate this into my normal skincare routine, meaning I used this after my normal toner and followed it with my normal moisturizer.<br /><br />I really like this serum, it absorbs very well into the skin, which for me is the biggest factor. It does not leave a tacky or sticky film on the skin. Also, a little goes a long way. Before, I have used other Korean brand skincare and serums like Skin&Lab Dr. Color Effect Red Serum and also Zymogen Ferment Houttuniya Cordata Extract Serum. I would choose 28 Day Remedy above both Skin&Lab and Zymogen. 28 Day Remedy is more effective for my skin regeneration and healing than Red Serum without the stickiness. Also it absorbs better and quicker than Zymogen and is more effective against acne on its own.<br /><br />This product did smooth my skin texture and any breakouts I had starting were gone by the next morning. Overall this is a very good product especially if you have had problems with acne in the past. I am giving it 4 out of 5 stars because the price point is a little high for most people. But this product does do what it promises on the packaging and is a quality product.<br /><br />-Sonya H.
