This is one of the best serums I've tried to date and if you've checked my reviews, I've tried plenty! I am using this for day under makeup because it really firms and tightens and the effect just seems to get better the longer I use it. Its companion product, Instant FirmX, (temporary tightener), works very well with this serum, too. A drop of the Instant mixed with this serum seems to diffuse the white residue problem of the temporary product, too. I use other serums at night, but this one really provides a great look when I am out and about even in bright sunny daylight (which we have a lot of here in Las Vegas). The ingredients in this serum are excellent with no offensive odor. A little goes a long way so the $150 price tag is not too overwhelming either. Definitely would recommend giving this a try!

With 47 year old moderatly sagging jawline - eye hoods' this product is truly a miracle. It lifts my eyes to look perfect - my jaw area tightens quickly and stays that way all day. No stinging or irritation. Really fantastic when you are truly trying to fix things.

I have had no problem controlling the dispensing of this product. I have combination skin, so I only use under eyes, over cheeks to jaw line. My cheekbones and jaw line are more defined. Price is pretty insane, but travels well and I am still on my first bottle after 4 months (though cannot tell how much is left)

I only use PTR products and and this is one of my favorites. It does get a little oily once applied and therefore I only use it at night. In the summer I find I do not need to add a moisturizer after. I use with the Glycolic wash and Glycolic moisturizer (daytime).

PROS: This has a lot of hype, but I think that's all it is. Didn't see a lot of difference.


CONS: I can tell you that this is not great for my oily skin because it is like adding an additional, oily moisturizer to my routine. Did not feel like a serum.
