<human>:  What type of skin care should I use?
<bot>: It depends on your skin type. If you have dry skin, you should use products that are hydrating and contain humectants such as hyaluronic acid, glycerin, and aloe. For oily skin, opt for oil-free, lightweight moisturizers and products containing salicylic acid to help control excess oil. If you have combination skin, look for products that can hydrate dry patches while also absorbing excess sebum in the oily areas. Finally, if you have sensitive skin, try to opt for products that are lightweight and free of fragrances and other potentially irritating ingredients.
