The Ordinary Ethylated Ascorbic Acid 15% Solution 30ml

It's fine to use. You can see a difference when you use it but don't expect miracles.

Hi, Thanks for reaching out to us. This product contains Vitamin C which an effective antioxidant that brightens the skin tone and reduces the appearance of signs of aging. The Ordinary Ethylated Ascorbic Acid 15% Solution offers a direct-acting form of Vitamin C, an effective antioxidant that has been shown to reverse multiple signs of skin aging while brightening the skin when applied topically. I would recommend this for use on a maturer skin that requires brightening, however I would definitely be mindful when using it. Vitamin C can make the skin more sensitive and can have an adverse effect on skin that is sensitive already. You could start by using this product every other day, then once a day, slowly building up to twice a day as recommended. I hope this helps! Thanks, Chloe - Beauty Experts
