Rated 5 out of 5 by from The best by far. I'm 59 years old and have had acne issues since my teens. This product by far has been the best I have ever used. It is long last, non drying and soaks directly into the skin. Three drops later if I do get a pimple its life is so short lived and on the surface, not cystic at all. I couldnt be more happy with it and the more I use a product my skin usually with act up at some point, but not with this. Try it at least, you will not be sorry. No reddness, pores looks smaller and I think it is evening out my skin tone and texture as well. SO good.

Rated 5 out of 5 by from New Favorite! kept acne at bay For the first times in ten years, I am able to keep my adult acne at bay with Blemish + Age Defense. I am 29 and have acne ever since college, Funny that I have very clear skin in my teen years. I have tried many product include murad, proactive, philosophy, olay, etc. The only things that work would be the product such as 2.5% Benzoyl Peroxide (BP). But the BP is very drying and makes my skin very sensitive and tender to touch. I also have breakout in my temple area; the BP would irritate my eyes. I addressed my concern to my facial esthetician, she suggested Blemish + Age Defense. I saw difference in my skin after two days of using this product. My skin had been clear since I used it and have not seen any new acne.

Rated 5 out of 5 by from Amazing product! When i started working in the spa industry i was introduced to many many skin care lines because my spa use a variety of products. However when i had my facial done , she did skinceuticalsl facial. I must say it was amazing! i loved how my face was so radiant and smooth! This product was recommended to me, and i bought it because i'm very acne prone. You can use it as a spot treatment, and you can use it with the clarifying mask together. you put little of this product and the mask then spot on the pimples that are coming out at night, wake up in the morning and wash it off and you pimple is gone and no spots! i'm a spa director i have done many facials with different products but this one was so good. i totally recommend it! it last long.

Rated 5 out of 5 by from Saving Grace I am 18 years old and struggled with moderate acne all of my senior year. Throughout high school really I felt like I tried every over the counter acne treatment and finally my esthetician referred me to this product and I was super excited. It was fabulous to first week, then I had a breakout for a few days, and after that my skin has cleared up tremendously!! My scars from the past year are going away, my pores are smaller, the few pimples that I get go away insanely faster, and I am feeling way more confident running errands with no makeup on. I use the serum morning and night. After I put it on at night I sleep with extra virgin coconut oil on my face to keep it hydrated and it works great.

Rated 5 out of 5 by from Glowing skin without the roughness and redness of acne I am a 61 one year old woman who still has oily skin. I experience sign s og aging and still have oily acne prone skin. A coworker was kind enough to mention how rough my skin was (thank you) and I decided to go on an expedition to find the right product for my issues. After nearly five years of searching, I found it in the Blemish Plus Age Defense! This really works and it only took a couple of weeks for me to notice the difference. I am truly thrilled with this product. I also use the B moisturizing gel and added the re-texturizing serum. I can't say enough good things about this product. It has changed how I view myself and I have added confidence now working in a business world where youth and beauty are valued.

Rated 1 out of 5 by from Poor manufaturing I liked this product and it helped with my occasional breakouts. I have very sensitive skin so I was not able to use it everyday. After a year...I had product left but the top of the bottle completely fell apart. The dropper literally came apart and the liquid evaporated. I called the company and they told me that the bottle is only guaranteed for 90 days and I should have used it up by now anyway. Will never order from this company again! There are so many choices out there and so many great products..the last thing I expect for an item which was rather costly is the the container to disintegrate!

Rated 5 out of 5 by from Excellent product for hormonal acne and scarring I very much endorse SkinCeuticals blemish + age defense for anyone that has persistent hormonal acne or scarring due to severe acne. I'm 25, didn't struggle with acne during puberty, but for the past few years have only tended to break out around my menstrual cycle; for an entire week each month, I would get painful and deeply rooted blemishes that would take days to surface and then be healed. This is the only thing that has reduced them significantly — almost nonexistent. (I get maybe one blemish a month that isn't too much of an issue.) I'm very careful about my skincare routine and use this every morning and night after a cleanser or toner. I've been using this for about three months with consistent results. Also, I never write review of products but did so this time. Be sure to get this if you're looking for blemish relief!!

Rated 5 out of 5 by from Liquid Gold This serum is unlike anything else that I've ever tried. I'm 24 and I have stubborn, cystic acne mainly along my chin and jawline area. My dermatologist introduced me to skinceuticals and I've been using the LHA cleansing gel and this serum in my skin care routine and I am so impressed that I have finally found something that actually works on my skin!! Granted, my skin isn't 100% clear after using these products but I am very impressed in how they work because I do feel that they have significantly helped in reducing the amount of breakouts I get. If your in doubt about trying this, I say go for it! If you have sensitive skin as I do, it will burn pretty bad until your skin gets used to it. Also, a little goes a long way, I think I made the mistake of applying too much.
