It is important to understand its role and relevance for our overall health, and to learn how to properly care for it. #2 Our skin is our body's natural heating and air-conditioning system. It protects us from harmful elements that might otherwise gain access to our internal systems. It also helps us maintain our overall health. #3 There are four basic skin types: normal, oily, dry, and combination. However, it is more important to provide your skin with what it needs. While there are specific ingredients that target different skin types, there are also commonalities in certain ingredients that benefit all types of skin. #4 The skin can be affected by a variety of issues, including blemishes, acne, eczema, psoriasis, redness or rosacea, sensitivity, hyperpigmentation, and seborrheic dermatitis.
