I adjusted this serum to three times a week at night after half years using, I see results is incredible, facial lines were about to fixed has gone, tones are even, I am 33 but I look around 25, most beautiful age.
Absolutely a Must have item in my routine, this is very useful for my wrinkles & fine lines, no product can do job like retinol, combined with ceramides(one of my favorites ingredient) it boost collagen growth and plump skin up, beats dryness, can't love it more.
