If you happen to have any new or unused beauty products laying around that you don't plan on keeping or using, a good way to get rid of them is to donate them. Organisations like Project Beauty Share distribute beauty and personal hygiene products to non-profit groups dedicated to helping people who are homeless and/or overcoming other obstacles like addiction, abuse, or poverty.
Other groups like Donate Beauty provide, skin and hair-care products, creams, hand sanitizers, and more to healthcare workers on the frontlines of the COVID-19 pandemic. Alternatively, if you don't have any products to give away, you can also donate money to some of these same organisations to support their causes.
