When I use this product consistently I notice my neck looks firmer. Make sure to use the product behind neck & ears for the most lift! The smell eventually dissipates. It doesn't break your skin out.
I have only been using Cold Plasma Sub D for a few weeks. It is hard to believe, but my neck sKin is much smoother, softer and supple. I did not have many deep wrinkles, but I can see a difference already. This definitely a product I will continue to use.
I have been using this product for several years. I use it morning and night. It is fine to us under makeup. Although I am 75 years old my neck is firm and smooth. I definitely feel this product has helped maintain that look.
