Alvera tone Our skin’s functions are too many to go through here in detail, however it protects our ‘insides’ from the external environment, acting both as a barrier and a filter between ‘outside’ and ‘inside’ the body's. The epidermis can be useful for regulating our body’s temperature, like when we have a fever or we’re physically creating an attempt, we tend to sweat, which is the body’s way to attempt to lower the temperature. The epidermis also protects us from dangerous ingredients entering the body's, and it eliminates many toxins. This takes workload off our Liver and Kidneys to filter out by-products from our body’s metabolism.
