TikTok can be great for some trends, like that whipped coffee craze and learning the latest dances. But not all the beauty tips shared there are keepers and dermatologistDr. Muneeb Shahsaysthese may even do more harm than good.
- DIY Microneedling- It’s the process of using a “microneedler” or “dermaroller” to create teeny tiny holes on the surface of the skin, which signal the body to go into repair mode, promoting new collagen and elastin growth which improves the texture and tone of skin. Some TikTokers share techniques for DIYing it, but Dr. Shah says, “Home microneedling is a terrible idea for most people!” Poking tiny holes in your face can lead to irritation, allergy and infection, so he advises saving this procedure for the spa or dermatologist.
- Coffee grounds face scrubs- Some beauty seekers are using their coffee grounds as a DIY scrub they say sloughs dead skin cells and firms up skin. And Dr. Shah is a fan of using coffee as a face mask because he says “the caffeine can help depuff and improve redness temporarily.” But he warns that coffee scrubs are too harsh for the skin, so use them as a mask - with no scrubbing - or use the scrub on tough body parts, like elbows and feet.
- Toothpaste on pimples- Fans say it shrinks spots overnight, but this skincare expert says toothpaste today is missing the ingredient that made this at-home hack popular back in the day. Dr. Shah says toothpaste used to contain triclosan, which had antibacterial properties that may have helped acne. But he says today’s toothpaste doesn’t have triclosan, just ingredients that are ‘not safe for the skin.”
- Potatoes on spots- Another breakout fix some TikTokers like? Putting potatoes on pimples, which Dr. Shah says is an old hack. He explains that potatoes contain salicylic acid, which is used in acne treatments and the starches in the spuds can help dry out bumps as well, but the benefits are unproven. Plus, who wants to hold or tape a tater to their face? Instead he suggests using hydrocolloid pimple patches or good old benzoyl peroxide for spot treatments.
