I ain't gonna put my wallet on life support for getting expensive products that I probably have somewhere in my house already
I cannot stress enough to you how many times I go back to baking soda. My holy grail of stuff I use for hygiene. From teeth whitening to using it as a face mask.
Baking Soda
I know I mentioned getting pimple patches, but I switched to hydrocolloid bandages SO quickly after I found out they are the same thing, but I get more uses out of one whole roll compared to a pack of those patches and it is way cheaper
Hydrocolloid Bandages
Whichever one you have USE IT. Doesn't need to be Vaseline or any specific brand, it'll still have so many uses. Lip mask, slugging, cuticle repair, friction prevention, brow grooming, healing dry patches and so on
Petroleum Jelly
Keeps piercings, irritated skin, and dry noses happier; also useful for eye irritation and travel. I still suggest reading instructions fully to know exactly if you can use it for stuff I just mentioned
Saline Sprays
Removes mineral buildup from hair tools, softens laundry, deodorizes fabrics, cleans brushes. Is it a replacment for normal detergent? No, but it helps
White Vinegar,
Get a tongue scraper becouse that is the main thing that helped me with bad breath. There are plastic ones, but I still suggest going for a metal one
Tongue
A good pair of tweezers will do wonders, and that is why I have multiple pairs for diffrent things
