Best product ever

Absolutely love this product. Starting purchasing in January 2026 and have been using morning and night ever since I received my first bottle. I have drawers of products at home that don't deliver but this one does. It is absolutely the best product ever.

75 year old female

I have always taken an interest in skincare. I worked in a Dermatology practice before retirement. Re Q has made my skin have more of a "glow" and plumpness. I used it on one side of my face for two weeks which convinced me to order more of the product. To those interested you should try this new pathway for your best face forward!

Re-Q is Phenomenal!

I’ve had actinic “senile” purpura on my forearms for years. My skin was delicate and I would cut easily. I’d get giant purple blotches from brushing against anything. I’ve tried everything to get rid of them with no success. I saw Dr. Day and she suggested using Re-Q on my forearms twice a day. I’ve been using Re-Q for 9 months now and I will never stop! Not only did the giant purple blotches disappear but my forearms are soft to the touch instead of leathery and I’m growing hair for the first time in 20 years! This product is a game changer! I can now walk around in short sleeves proudly again. Thank you Dr. Day!!!

Best product I have ever used

my skin has improved significantly since I've been using RE-Q. It is very smooth and has been a very big difference in the wrinkle texture under my eyes. Will continue to purchase, on my third bottle and it is has exceeded my expectations.

Seeing Subtle Improvements Daily

I just received my second bottle of Re-Q. I have been using daily to boost collagen on my 65yr old skin and to firm up my skin. I also have some areas that are a little "pinker" than other areas due to a procedure I had more than 6 months ago. I have noticed subtle but very visible improvements for all the things I was seeking to improve and that is why I just bought another bottle. I really like the results. I too, am not fond of the price, but with any new technology one can expect to pay more at first and I am willing to accept that as long as I can continue to see great results. So far, so good. I also trust and respect Dr. Day's approach to battling aging skin. Kudos Dr. Day! Keep up the groundbreaking work.
