I'm 51 and I have had good skin my whole life until perimenopause, when I began getting stubborn acne. Within 2–3 days of using the serum, I noticed my acne beginning to clear up.
My hygienist had to double-check my date of birth. She couldn't believe I was 60.
Better than Shiseido and Lancôme serums. I've been using facial serums for 14 years, and Caire's was immediately absorbed by my skin.
