Hi — I look after the “Function of Beauty” page here at WaveDeals. I've covered beauty & cosmetics promotions since 2019. The list above is refreshed daily from Function of Beauty's affiliate program; when a code is reported as not working I check it against the retailer's terms. The deepest savings at Function of Beauty tend to appear during sale events and via sitewide codes. Please double-check the offer details, as Function of Beauty can adjust terms and some codes only apply in certain regions.
