"This Vitamin C Serum is most definitely the best one I’ve used. It immediately is absorbed into your skin making it feel luxuriously silky smooth. Then I use one of my Yonka moisturizers and sunscreen to finish and my skin feels so soft. I have noticed a huge difference in my skin since I started using this serum, which is about 8 months ago. My skin feels super refreshed! Just love it and highly recommend!"
"Look radiant on facial skin and chest areas. Do not notice a difference with fine lines. Dark spots from sun damage have lightened some. I have been using the product daily over six months. A couple drops go a long way. After my skin is cleansed and toned I apply the vitamin C underneath my regular skin care mornings."
"As I just purchased this serum for the 1st time, I cannot speak to the long term effects of the product; however, it is light weight, absorbs quickly, and has a pleasant smell."
"Using for three weeks, my skin is clearer and brighter. Excellent moisturizer before bed."
"it is helping with the sun spots y with the sagging areas. the best product ever"
"After a few weeks of using this, my esthetician asked what I what using! She noticed how soft and even toned my skin looked. My ESTHETICIAN knew I found something that actually works! Of course, she has taken my recommendation and is now a Yonka customer."
"Great serum!"
