Toxic and Scratchy
Cotton is the most pesticide-doused crop on the planet. Pesticides used on cotton are super toxic and extremely long-lasting. So it’s likely that your cheap cotton balls, rounds, and pads have harmful pesticide residues on them, and they’re the kind of toxins that can get into your body through your skin. You can wash your T-shirts and jeans before use, but there’s nothing you can do about toxic cotton balls.
Besides the toxin thing, cotton isn’t great for skincare. Cotton products are really good at absorbing and scraping, but not very good at grabbing the grime. Expensive ones are softer, but the cost can get out of hand.
