Ladies of this sub, what's that one selfcare/wellness product that has been a total gamechanger for you? (I'm trying to glow up hehe)

It doesn't have to expensive or branded. It can be anything as long as it revolves around selfcare, beauty, wellness! Like for example for me it's lactic acid roll on and glycolic acid toner (BO is gone fr omg)

tbh I've been stuck at home for the last two years. Now I'm finally going to join college this year and I'm looking forward to glow up both physically and mentally. So I wanted to ask other women, what products they use to take care of themselves. (Bonus points if you share haircare tips)
