Amino Acids + B5

A Concentrated Hydration Support Formula

6.80 CAD
This concentrated solution includes Amino Acids and Amino Acid derivatives creating a combined total concentration of 17% (by weight). This resembles the composition of Amino Acids found in the skin’s own Natural Moisturizing Factors and provides enhanced barrier support, elasticity, osmotic balance and desquamation. The formulation also includes a 5% (by weight) concentration of D-Panthenol which is a pro-vitamin of Vitamin B5 to provide surface and below-surface hydration while aiding in skin repair and anti-irritant functions.

Amino Acids + B5 offers non-greasy hydration support for the maintenance of healthy, functioning skin. It may cause a temporary tingling sensation upon application. If desired, the formula can be mixed with other serums or creams upon application to reduce its strength.
Apply a few drops to face in the AM and PM before creams. A tingling sensation can be expected after application. If the sensation is too strong to tolerate, the formula can be mixed with other creams or serums of your preference before each application to reduce the strength. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children.

Rated 3 out of 5 by from Still on the fence about this product! I have to give 3 stars to this product because, after using all the content of the bottle over the course of various months, I am still confused about whether I actually liked it or not. For a bit of context: I have dry skin, which can really only take as much in terms of the amount of products I layer, and of how thick they are; I initially bought this serum in the hopes of it providing an extra layer of hydration under my moisturiser. The aim was to avoid embarking on the never-ending quest for a light-yet-effective moisturiser that my skin could handle, so I thought this water-based would do the trick of provding extra moisture without any added heaviness. It initially caused breakouts, but they eventually faded after a few days of consistent use. So far so good. BUT what never really changed over the course of time was the sticky finish that it left my skin covered in (which I really didn't look forward to, considering that I bought it very much to avoid this thing, which also tends to happen with thicker moisturisers). Nothing I did ever really managed to solve this problem (I tried applying less of it, layering it with less products, using it by itself, applying it on damp skin to improve absorption). On this note, I very much agree with some reviews I read that claimed it left a sticky film on the skin, which resembles very much what you would be left with if you were to apply fruit juice or sugary water on your skin and let it dry. So be warned! On the other hand, I have to give it an overall positive review (hence the 3 stars) because it has actually helped me in restoring my skin barrier which has been wrecked as of lately because of all the face-mask-wearing, overwashing, irritation and dryness shenanigans that have come along with this pandemic. I have actually come back to it after discontinuing it for a while for this very reason (but only at night time, when I care less if my skin feels sticky). I feel it actually has contributed to making my skin barrier stronger, which was very much needed at this time. Overall: this product can be useful, but I won't repurchase it for the time being.

Rated 5 out of 5 by from I LOVE THIS I'm already at my second bottle! This has been a miracle for my skin! I recently had to change my sunscreen due to the manufacturer removing the product from sale. I now use a European sunscreen with some alcohol i normally have combination-dry sensitive skin. My skin was getting so dry! A friend recommended this and i decided to try. Its veeery watery so I apply it to the palm of my hand and pat it on my skin. It instantly boosts hydration and radiance, my skin looks so radiant people think I'm wearing make up when I'm not! I sometimes use a vitamin c serum afterwards and my skin seems to love this. I highly recommend

Rated 5 out of 5 by from Beautiful serum It’s a very thin consistency and easy to distribute. It leaves the skin instantly hydrated, feeling moisturised and plump. It gives a gorgeous, natural glow from within to the skin that shines through. The skin stays hydrated all day.

Rated 5 out of 5 by from Excellent product for dry skin I had very dry skin and my forehead felt like sandpaper! I had used all kinds of moisturizer but I wasn't happy with any of them. This product is great! My skin now glows, has much more elasticity and I can feel it fresh and moisturized. It's very easy to use and not at all oily.

Rated 2 out of 5 by from Sticky Was really excited for this product as I have dehydrated skin and this sounded like the perfect thing - but it's very sticky and leaves my faces tacky for hours. :(

Rated 5 out of 5 by from Dewy Skin I love this product. It goes on easy (although I find I run out of it quicker than other products but it's a great price point so it doesn't matter) and leaves my skin so plump and dewy. I have sensitive rosacea skin and this does not irritate it at all. I will keep purchasing this as a staple product.

Rated 5 out of 5 by from Amazing Revitalization I've been struggling with dry patches of skin on my cheekbones. Since I started using this serum (combined with the Squalene cleanser and Natural Moisturizing Factors + HA), in just a few weeks I noticed a huge improvement in my skin texture. The dry patches are completely gone and the redness is fading with every single day. I highly recommend this product - it provides great hydration and soothes the skin!
