Rated 5 out of 5 by from Perfect for antiaging. Will buy again. My skin looks better

Rated 5 out of 5 by from Excellent Product I really love this product. Since I’ve been using it my skin looks much smoother.

Rated 5 out of 5 by from Worth it! I love all skinceuticals products and P Tiox does not disappoint. My skin looks and feels smoother after I use it. I combine it with HA intensifier for better results. I definitely recommend it!

Rated 1 out of 5 by from Not good for oily skin! I wanted to love this product as it had so many good reviews, but it has brought me out in massive spots as well as making my skin red and bumpy. Can’t believe I paid over £100 for something that has made my skin so congested.

Rated 4 out of 5 by from Worth the purchase I have seen this product for probably over a year now use by various different people (some influencers but others people such as atheistic clinicians). The texture is lovely and I feel it does give your face a “tighter” feel in the morning. I’m pretty confident it is going to work well to maintain my Botox!

Rated 2 out of 5 by from Not for acne prone skin type I have always love Skinceuticals products, especially the CE Feeulic for the last 10 years. Unfortunately this new product is not for me. After using it for a week, I started to have unexplained little spots popping out on my face. I had to stop using this product and it took 1 to 2 weeks before my skin has gone back to normal again. I think you should review the formula or put a warning sign for people who have acne prone skin to avoid this product.

Rated 5 out of 5 by from Nothing better! Fantastic project. Can see a definite difference after using this product. My wrinkles and fine lines ate definitively softer. Probably the one product I will always get if if it costs a little more.

Rated 4 out of 5 by from Skin smoothing serum After applying the serum for a few weeks with a vitamin c serum first followed by the p-tiox, I did notice a smoother texture, maybe a slight fading of fine lines, but not any difference to deeper line and wrinkles.
