Do not buy Youthology.
We tried Youthology and it doesn't work.I called to return and they told me I was 2 days too late from the 30 days of delivery, so they said there was nothing they could do for a refund.
However, there is a paper in the box that states you have 6 weeks to call. Youthology has $100 of my money on a product that's a fake. You can get better results from items from Macy's cosmetic counter.
Shame on you Youthology for ripping off the public.I will now spend my time letting people know NOT TO ORDER THIS PRODUCT.
