    Blemish + Age Defense


    Blemish + Age Defense

    Salicylic acid acne serum. An oil-free anti-acne face serum that reduces the formation of adult acne, and improves visible signs of aging

    Blemish + Age Defense is a targeted, oil-free approach for aging skin prone to breakouts. This first-to-market acid blend combines 2% dioic acid with an optimal alpha- and beta-hydroxy acid formulation to reduce the formation of acne and clogged pores, while improving the appearance of fine lines, wrinkles, and uneven skin tone.
    • Reduces excess sebum production
    • Improves the appearance of blotchiness, blemishes, and uneven skin tone
    • Decongests clogged pores
    • Diminishes visible signs of aging
    • Ideal for acne-prone, oily, combination, and aging skin types

    Visible Results

    In a dermatologist-controlled 8-week study of 50 multi- ethnic subjects ages 25-50, Blemish + Age Defense reduced sebum by 39% and improved fine lines by 28% at week 4.

    After 1 week


    This powerful, targeted anti-aging serum addresses adult acne and signs of aging with a one-of-a-kind technology of dioic acid, salicylic acid, LHA, glycolic acid, and citric acid to fight the formation of acne and reduce excess sebum production as it helps improve the appearance of fine lines, wrinkles, and rough surface texture that can lead to an aged appearance.


    Once or twice daily, apply four to five drops to dry skin.

    Highly recommend


    This is a GREAT product. I do have some mild adult acne. This product truly does what it says it's going to do. Evens out skin tone, feels like it exfoliates the skin well and helps with wrinkles. Cannot live without this product. Since I do have congested skin, I also use the Blemish Age cleanser which is another amazing product!! A must have!!!

    Really works


    I am amazed and so happy to have FINALLY found a product that is effective on my adult acne! :-) I have ALWAYS had pimples, but then I keep getting a couple more and am never actually clear. Until now. I saw an immediate difference when I started using this product. It didn't dry out my whole skin, just the clogged pores themselves. I've been using this product for 2 weeks now and am completely clear. I am amazed and so happy. I have already ordered more so I don't run out and would absolutely recommend to anyone who has been searching for a product to clear adult acne.

    Works Wonders


    It is amazing that a product actually does what it claims to do! I have many skin issues including acne, oily T-zone and aging. This keeps my skin clear (I can definitely tell when I don't use it 2x a day) and smooth. It is expensive, but a little goes a long way. It is worth every penny.

    Simply Amazing


    I recently went off the pill and suddenly had to battle acne all over again like I was a teenager. This has worked for me like nothing ever has before! It's incredible. I had the worst break out and this stopped it in its tracks and got rid of all the marks it left behind in less than 2 weeks! Two weeks later my skin is so balanced and hasn't broken out at all. It's like I needed this stuff all along and just never knew it. I have oily, sensitive and acne prone skin for those wondering.
