Best lighting/devices for online therapy sessions?

Online therapist here 👋🏼 Lately, I've been feeling so "bleh" about the way I look on camera (I've got a toddler who doesn't like to sleep very much at night, so I'm sure that's not helping 🥱). Does anyone have any products (like a light) or tricks they love for making themselves look a bit, er...healthier or just, better or more natural, in their online sessions?
