Our skin needs a lot of water to keep its youthful glow. If your skin is not getting enough water, you will witness signs such as dry, flaky and irritable skin. Dehydrated skin, often confused with dry skin, is the lack of water in the skin, whereas the latter is the lack of oil in the skin. Knowing the difference will help you a great deal in making the best choice for your skin! By hydrating your skin, you retain the water content even in the skin’s innermost layer.
