<human>: I have a very bad case of acne, and I've been told I need to start using a topical retinoid. What do you think?
<bot>: I’m not sure what that is, but it sounds like a good idea! Retinoids are used in skin care products to treat acne and other skin conditions. They work by reducing oil production and unclogging pores. It's important to use the right product for your skin type and condition; ask your dermatologist if they can recommend one.
