What is the difference between this product and the powerful-strength line-reducing concentrate?
A shopper on Jul 13, 2013
Best Answer: My experience with the skin firming concentrate is that it has more visible results immediately. In firming the skin, the wrinkles are much less noticeable, and the effect is after each application rather than waiting for results on a much longer-term basis.

is this product good for sagging jowls and chin?
sandra c on Apr 18, 2012
Best Answer: It does make the skin feel and look tighter, smoother, and more hydrated, but unfortunately I don't think it would reduce skin that's already noticeably sagging.

Are there any 50+ year old people who have used this?
A shopper on Jun 24, 2012
Best Answer: I am a 58 year old female-Have finished the first bottle that I purchased-This
product really goes a long way-It doesn't take that much , so it lasts a long time. I will buy this product again. I think it helped, but let's face it-to completely get rid of lines or wrinkles will take more than something in a bottle! A good buy for the money.

can it be used in combination with filler ?
A shopper on Mar 22, 2013
Best Answer: I can think of no reason it wouldn't be perfectly fine with fillers such as Restylane or Juvederm. And if you're talking about Botox, it isn't actually a filler, but reversibly paralyzes muscles. Cosmetics/creams/potions of any kind would have no contraindications. Actually, I think it would work well in combo with fillers.

Can i use my dark spot solution as well? If so should i apply first? The dark spot solution or high potency firming? And should i use it both morning and evening?
A shopper on Sep 24, 2014
Best Answer: I have used the products together. I apply both at night only because they tend to leave my skin a bit oily. I am not sure that order of application matters, but I typically apply the dark spot solution first.
