Softens the skin
I definitely noticed a purge at first but expected this as certain routines that work hard on your skin will do this. After the first week my skin readjusted and I started to notice a more glow and so did others! It softened down some of the deep wrinkles but it didn't seem to help much with my eye crowd feet. It helped with my 11 lines and my smile wrinkles though! It didn't dry out my skin or cause any burning. The product was easy to spread and a little bit goes a long way. The dropper made it easy to apply just the right about to my clean hands and then massage into my skin. I followed up with a lotion and sunscreen as recommended!

Smoothed expression lines immensely
This has been one of the best serums I've used in a while in regards to my fine lines around my eyes, mouth, and forehead. I feel like this serum is a little thicker and stays in place better when applying it to those areas.

Wow did this help with fine lines!
I received this product a few months ago for free and was super excited to try it. I am a big fan of Skinceuticals already and a lot of aestheticians in Scottsdale use their line. The P-Tiox is a serum, that you use 2x daily. It took a few weeks to really notice the difference, but I really started to see my skin smoothing out in about 3-4 weeks especially smile lines and forehead. I will definitely order this product again and keep in my regimen.

Effective
I received this product from skinceuticals free in exchange for my honest review, it has a serum texture that absorbs quickly into the skin and layers well with other skincare products. Its main star ingredients are two peptides - hexapeptide and dipeptide that work together to reduce expression lines all over the face. Its main supporting ingredients include PHA, Niacinamide, and laminaria extract that provide hydration and gentle exfoliation to leave your skin radiant and renewed. I haven't experienced any irritation while using and have already begun to notice a marked difference in my nasolabial folds and the small lines between my eyebrows. I'm super excited to see what continued use…
