Aloe vera or the natural aloe are very helpful for the skin especially when the skin is irritated .but when we talk about the aloe vera gel, made by medical companies, it cannot be bottled without putting any preservatives or chemicals. So what you might be thinking is plain aloe vera gel. If you are using natural aloe vera, directly from the plant, it is very safe to use. It is an anti-inflammatory, that means it can ring down the irritation of the skin and can be left as a moisturizer overnight. It is not going to do any harm to the body. But if you are going to use aloe vera gel, which is a bottled product, even if the company may say it is chemical free, you have to think how can an aloe vera survive in a bottle for months together. So the next guide in helping you selecting a good hydrating product is a dermatologist, they can say if a product is chemical free or if they have to sick with natural products.
