A lot of you will already know that I only swear by beauty skincare products that I find work. I haven’t always been the person who has believed in night-time skincare, purely because I didn’t know what benefits it had on my skin or perhaps didn’t see any results other than my religious daily skincare routine. However, honest honest…the new SkinCeuticals Glycolic 10 Renew Overnight Treatment has changed that. I have been using this product for just over a month and have visibly seen my skin improve in several ways. I have always believed that your skincare products are an investment and that what you put in is what you get out. Over the past few years, I have struggled with dark marks, pigmentations and dull skin (which I never had when I was younger) but with lots of care and really sticking to brands that have worked for me has really helped my skin get to a place I’m happy with. So why does this overnight treatment work, what does it help with and why this product?
