What is the difference between a facial moisturizer, a facial oil, and a serum or gel?
A moisturizer is a cream or a lotion that is a blend of water, oil and plant extract.
An oil contains no water, only plant oils rich is antioxidants, vitamins and essential fatty acids. They also penetrate deeply into the skin leaving it velvety soft.
A serum contains less oil, more liquid and most often contains very potent concentrated plant ingredients without being heavy. Serums absorb almost immediately leaving your skin feeling hydrated, brightened, tightened and toned.
A gel is very similar to a serum and often contains a plant gel such as Aloe Vera as the base. It also usually absorbs quickly for instantly hydrated skin.
