Absolutely Love this product

I use the SKINFIX Barrier+ Triple Lipid Activating Serum with Plumping Peptides and Niacinamide as the fifth step in my morning routine and the fourth step in my evening routine. Two pumps go a long way, and the texture is lightweight yet nourishing. It applies smoothly, absorbs beautifully, and leaves my skin feeling comfortable and hydrated. I work outdoors for eight hours a day, so protecting my skin barrier is extremely important, and this serum has become a must-have in my daily skincare routine. It layers well with other products and delivers reliable, consistent results

Love, but the price?!

I absolutely love this product!!! Smooths my skin and helps my redness, too. But I give it a 3 Star because I need to use a at least 4 or 5 pumps each use to see results, so it doesn’t last more than like two weeks ): Also, the pump doesn’t really work.

I think the moisturizer is a better investment

I bought this to pair with my 360 eye cream and skin fix moisturizer - not too sure if I actually saw any physical difference but did add hydration to the skin. I have extremely sensitive skin & this did not cause breakouts which was nice.

Must try!

So good! Use it everyday and can really see a difference. Feels great and isn’t sticky. I have sensitive skin and this works great for me.

Please upgrade the packaging!!

I actually really like this product. My skin drinks it up! However, my biggest problem is that the lettering on the packaging comes off after so many uses. When you use other skin products before this one, the letters start to come off and all of a sudden, you have bits and pieces of the letters on your face.

It gave me Contact Dermatitis

Listen to the reviews about negative reactions and patch test. When I applied this serum there was a slight stinging sensation but I ignored it because in the past it meant I might have been too aggressive with my tretinoin use. I actually bought this serum to help support high tret use, but the next morning I woke with tiny red and white pumps all over mid and lower face which turned out to be contact dermatitis. I used it for about two more days before I realized it was the serum and not irritation from my tret.

I started using this serum in October–November, and now that it’s March, it has already become a staple in my routine. It really stands out more for its soothing and smoothing effects than for hydration. Every time I apply it, my skin instantly feels softer, smoother, and silky to the touch. It also helps reduce dullness, giving my skin a fresher and more refined look almost immediately. Also works great under makeup.

Burns!!

This causes my face to burn terribly. I don’t have sensitive skin and don’t normally have issues with ingredients, but it seems that I must not be able to tolerate something in this formulation. Test first!

An effective addition to my skincare routine

This stuff works. Dry patches on my forehead are gone. Just need a drop or two every day. Refill is well designed and helps save a little money with repurchase due to the lower price.

Niacinamide Sensitivity — WATCH OUT

Used a sample of this, and WOW, do I regret doing that. Had an almost immediate reaction (bright red and flushed skin, hot to the touch) to the niacinamide in it which wasn’t made clear on the sample’s packaging or I never would have used it. Anyone with a niancinamide sensitivity, WATCH OUT.
