[Product Request] what can be poured into a bath to benefit the skin?

I’m lazy and struggle to follow a routine- but something I always do without fail is a long bath every night.

Is there any concoction I can pour into my bath that can help my skin (on my body)?

I have no major skin complaints- just anything that is beneficial for moisturising, texture or plumpness.

I don’t moisturise my body because I have sensory ick about my body being ‘wet’ with moisturiser and needing to get dressed, and no time to let it seep into my skin properly.

Would be good to use this time to care for myself!
