I've only used the Sensilift once as it's a weekly treatment but will report back!
However I'm delighted with my skin at the moment- I used the bear with the Nuface gel this morning and I'm going to stick with the Nuface gel and not rinsing on both the Nuface and the bear except maybe on UFO days. The Bear works far better with the Nuface gel than a water based serum IMO. I only discovered it by accident as I had run out of serum. The other thing is that I've been working from home, the office tends to get stuffy so maybe that's another reason why my skin looks better.
I've also just purchased a three week course of Gold Collagen drinks after hearing a few rave reviews (from real people, not influencers!) The recommended course is 9 weeks so going to try that as a boost
