Yesterday I was reading the reviews of freeze 247. It was stated as the best wrinkle cream as per the review done in December. But what I want to know as the reviews said that the cream shows instant results, will it be safe to use during day time? I read full review but did not find anything related to its use in day or exposure to sun. So I want to know can I use it in day. What are your views about the freeze 247 reviews?
