It smells amazing and feels even better.
The body oil is so luxurious without feeling greasy. I use it after every shower and my skin has never been this soft. Bonus: the scent is light but lasts all day. -

I wasn’t expecting to love it this much.
I bought the lip balm on a whim — now I keep one in every bag. It’s super hydrating and gives a slight glossy finish without being sticky. -

My scalp finally feels calm.
I’ve tried a dozen products for my itchy scalp, and nothing worked long-term. The treatment oil from IMYME BEAUTY changed that — no flaking, no itch, just clean and calm.
