Science & Proof

This powerful, targeted anti-ageing serum addresses adult acne and signs of ageing with the unique 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. Blemish + AGE Defence was shown to be as effective as the leading prescription drug combination, 1% clindamycin and 5% benzoyl peroxide, for the treatment of acne.

Clinical results were seen as early as day 2, with Blemish + AGE Defence significantly reducing inflammatory and non-inflammatory lesions.
Additionally, Blemish + AGE Defence also reduced blotchiness and clogged pores for the entire duration of the 8 week study. (Baumann, L. Comparison of clindamycin 1% and benzoyl peroxide 5% gel to a novel composition containing salicylic acid, capryloyl salicylic acid, HEPES, glycolic acid, citric acid, and dioic acid in the treatment of acne vulgaris - JDD - 2O13).

Blemish + AGE Defence was proven as effective and tolerable as 0.025% tretinoin in both anti-ageing and anti-acne attributes - B+AGE produced statistically superior improvements in skin tone, evenness and clarity, and a reduction in blemishes and blotchiness.
As early as day 2, B+AGE provided improvements in skin tone evenness and clarity, skin smoothness, skin brightness, clogged pores, blemishes, and blotchiness. Parity was achieved between the two treatments in reduction of fine lines, clogged pores, tactile roughness, and dullness.

At no point during the 8-week study did 0.025% tretinoin statistically outperform B+AGE. (Kircik, L. Safety and efficacy of two anti-acne/anti-ageing treatments in subjects with photodamaged skin and mild to moderate acne vulgaris - JDD - 2012).
After 4 weeks, Blemish + AGE Defence was proven to statistically reduce the grade of PIH by 19%.
After 8 weeks, it was proven to reduce the grade of PIH by 36% and the number of PIH marks by 29%.

(Protocol: 8-week dermatologist controlled study consisted of 59 subjects. The subject group consisted of males and females of multi-ethnicities, between the ages of 18-40 with skin types II-V that included mild acne and combination to oily skins, with at least 50% experiencing post-inflammatory hyperpigmentation).

Effective!
Works so well! Using on face, for crows feet, 11 lines, forehead and especially under eyes. It is reducing pores, diminishing fine lines and wrinkles, and giving glowing skin. Also using on elbows, wrinkled hands, and an old scar on my foot. My hands are plumping up and looking more youthful. The dark spots, discoloration and scar are fading and I’m sure will be fine with continuing use. A word of caution though - don’t use on eyelids because it will break off, thin out and damage eyelashes. I found that out the hard way and am now using lash serum to grow my once naturally long and healthy eyelashes back. They became half the length, much thinner and brittle. But skin is looking good and folks are starting to comment! Only use around the orbital bone and avoid the lash lines!

Ladies! Get this!! Especially if you're beginning to get wrinkles!
Im new to serums. Im 43 with problem skin, acne scars, and early signs of aging. I did a lot of research on what vitamins my skin is missing at this age and with my health issues. Everything pointed to topical retinoids and niacin. I am an absolute skeptic when it comes to the skin claims. I figured the price is right for something I can try for the first time ever. First off: the bottle is huge. Its simple and well packaged. It doesn't have any weird scent. Its yellowish but so are b vitamins so 🤷. Second: i put this on after showering and patting dry. Its definitely something to apply in the morning as it leaves your skin feeling very dewy. I rub in all over my neck and face, really working it into my crows feet and frown lines. Third: you will have glass skin alone with this but you should still apply a sunscreen. In about 3 weeks ive noticed 1 how soft and supple my skin is, how much my skin literally glows, my skin tone is more even, my acne has almost completely cleared. 1 month later of using 4 pumps daily and I still have over half the bottle left. Im sold. This is a game changer in my over 40 skin routine.

Excellent beauty product for mature skin
I have gotten at least four or five of my friends to use this product. It is by far one of the best serums that I’ve used. I think the most noticeable difference is the firming and plumping of my skin and the reduction of fine lines and large pores, especially on my forehead. I will definitely continue to use this. Once a day at bedtime seems to be enough and plenty and for the price it’s a large bottle and it seems to last a long time. It’s a great deal.

Definitely give it a try!
This product is fantastic! The bottle is huge, and even with twice-daily use (two pumps each time, enough to cover my face, neck, and chest), it lasted me an impressive eight months. I just ordered my second bottle. The retinal formula is incredibly gentle and is the only retinal product I’ve tried that doesn’t irritate my highly sensitive skin. It’s lightweight, absorbs quickly, and leaves my skin looking smooth, plump, and healthy. I highly recommend it!

Soft, Hydrating, and Long-Lasting Moisture – Great Everyday Body Wash
Scent: Fragranced, Size: 30.6 Fl Oz (Pack of 1)
I really like this Dove Body Wash Deep Moisture. It leaves my skin feeling super soft and hydrated, almost like I used lotion right after showering. The “24hr moisture” claim actually feels pretty accurate because my skin doesn’t dry out like it does with other body washes. It lathers nicely, smells clean and not too strong, and I also like that it’s made with no sulfates or parabens. The bottle is a good size (30.6 oz) so it lasts a while too. Overall, it’s a really solid everyday body wash and one of the best I’ve used for keeping my skin smooth and moisturized.
