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).

Power Chewer Loves This!
Size: Medium, Color: Antler
This is my dog's new favorite chew! She loves that she can hold it in her paws. I think she really loves the taste and texture of it. I don't give her antlers as I have heard too many horror stories about broken teeth. I also don't give her nylon toys as I have also heard a lot of horror stories of broken teeth as well as concerns about them digesting the plastic. This is between antlers and bully sticks, which is perfect for a power chewer. I feel comfortable with her eating the pieces that flake off this toy. She loves chewing and she will default to this toy when she wants to help calm down. I don't notice much of a smell. It does flake, but not enough I will even take a star off. Plus, it's plant based and vacuums up easily once dried. It doesn't capture her attention as much as bully sticks or beef cheek chews, but it's much less expensive over time and doesn't stink up our living room! She will also always pick this over any of her rubber chews. Great product and recommend it for all the power chewers.

Crumbly, odd texture
Size: Large, Color: Duo Pack
Neither of my dogs were very interested in these. They did chew on the antler-shaped versions more so than the infinity-style versions. When they did chew on these, they didn’t hold up well or last long. These have a strange, crumbly texture when chewed. You’ll find bits and pieces of these chews where the dogs have been chewing. Will not be reordering.

This appears to be a good alternative to the hard plastic chew toys.
Size: Large, Color: Duo Pack
My dog is a heavy chewer. I decided to try this brand out after using a different brand for quite awhile. while my dog seems to like it and carries it around (the pretzel shaped one) he doesn't seem to attack it as whole heartedly as his old brand, I'm thinking it might be the shape, we will see when he wears it out and I switch him to the antler shape. What I like most about it is it doesn't tear my hand up like the other brand did after he had been chewing it for awhile. While it is wearing down some it seems to do it in a more mild manner. Since we haven't had it long I would give this 3.5 stars because I don't know if it will last as long and not sure f it is just the shape that has him more mellow with it.

Choose your shape
Size: Medium, Color: Duo Pack
I love the idea of the dogs not eating nylabone plastic so have been searching for "healthier" options that last for heavy chewers. Two German Sherpherds, they are not big fans of the circular shaped toy but love the antler shaped one and even with both chewing on it, has not been destroyed yet and is not cutting their gums open. I am not finding pieces laying in the carpet. Recommend this
