My pores have tightened!!! I've been struggling with pores in my T-zone for a long time, and I've tried a lot of things, but nothing has helped... But this product is the first to really make a difference!! I'm so happy!! It's smooth and moisturizing! Fragrance-free! It's perfect for my dry skin!
I've been interested in this for a while and finally bought it. When I put it on my skin, it looks brighter and my skin tone is brighter. It also makes my skin softer, which I like.
I had been using vitamin supplements before and they were great, so I was interested in these. The fact that they are individually packaged for each dose makes them hygienic and also helps you know the dosage.
I had high hopes for this one, as I had enjoyed the Vitamin C serum. I was more impressed with the Vitamin C, but this one also feels okay to use. This one alone won't improve wrinkles, but when used in conjunction with other wrinkle creams, the effects are even more noticeable. It also makes my skin less rough and smoother. I was so glad I bought it before my photo shoot. It's a single-use product, so it's convenient for traveling. I can use coupons with repeat purchases, so I'll buy it in bulk when I get a big point reward. As others have said, I wish there were 30 in each box.
