The internet has always been a breeding ground for creativity, but in recent years, DIY culture has exploded across social media platforms. From beauty tricks to household fixes, influencers and content creators make certain hacks look effortless—and sometimes even genius. But behind the glitter filters and sped-up tutorials, a darker reality is emerging: some of these viral DIYs are not only ineffective, they’re downright dangerous.
Professionals in medicine, home repair, and chemistry are stepping in to sound the alarm. With likes and shares outpacing safety checks, it’s important to take a closer look at which DIY trends should be approached with serious caution.
1. Using Sunscreen Mixed with Highlighter for a “Glowy” Look
Beauty influencers have popularized a hack where liquid highlighter is mixed with sunscreen to create a shimmery base that supposedly offers both protection and radiance. Dermatologists strongly advise against this trend because it alters the chemical composition and consistency of the sunscreen, potentially reducing its ability to block harmful UV rays.
Mixing other products into SPF can dilute the active ingredients, leaving skin vulnerable to sunburn and long-term damage. While the look may seem appealing for summer photos, the health tradeoff is not worth the glow. Professionals recommend applying sunscreen first, allowing it to set, and then layering cosmetics on top for safer results.
2. Fixing Tooth Enamel with DIY Nail Files or Emery Boards
A concerning dental trend involves people trying to “even out” their teeth using nail files or emery boards, often after being inspired by viral before-and-after videos. Dental experts have repeatedly warned that this can cause irreversible enamel damage, which weakens teeth and increases the risk of cavities and sensitivity. Unlike hair or nails, enamel does not regenerate, and once it’s gone, it’s gone for good. Some individuals have experienced pain, infection, and the need for costly dental repairs after trying this at home. Dentists urge people to seek professional consultation before attempting any form of reshaping or filing.
3. Sealing Small Cuts with Super Glue Instead of Medical Adhesives
In an effort to avoid a trip to the doctor or save on medical supplies, some DIY enthusiasts have started recommending household super glue as a substitute for medical adhesive. Although cyanoacrylate—the main compound in super glue—is similar to the substance found in some medical-grade glues, household versions often contain additives that are not safe for open wounds. These additives can irritate skin, delay healing, and increase the risk of infection or allergic reaction. Medical experts emphasize the importance of using products specifically designed for wound care. In emergencies, store-bought first aid glue should be used only as a last resort and with proper precautions.
4. Using Drain Cleaner to Unclog Toilets
Home improvement creators have encouraged people to pour drain cleaner down toilets as a fast and powerful way to unclog them. Plumbing professionals and chemists alike warn this is incredibly dangerous because most drain cleaners contain highly corrosive chemicals meant for sinks, not toilets. When used improperly, these substances can react with water and organic material to release toxic fumes or even cause splash-back burns. Additionally, the chemicals can severely damage pipes and septic systems, leading to expensive repairs. The best approach to a clogged toilet remains a plunger, auger, or a professional plumber.
5. Whitening Teeth with Hydrogen Peroxide and Baking Soda
TikTok and YouTube are flooded with videos showing people applying homemade pastes made from hydrogen peroxide and baking soda to whiten their teeth. Dental professionals are pushing back, explaining that while both ingredients are found in commercial whitening products, they are carefully balanced and used in specific concentrations in those formulations. High concentrations of hydrogen peroxide can burn gums and damage the soft tissues inside the mouth, while abrasive baking soda can wear down enamel over time. The short-term whitening effect may look impressive, but it often comes at the cost of long-term oral health. Safer alternatives include ADA-approved whitening strips or in-office dental treatments.
6. Removing Moles and Skin Tags with Apple Cider Vinegar or Garlic
Some social media posts suggest using apple cider vinegar or raw garlic to remove skin tags, moles, or other skin imperfections. Dermatologists strongly oppose this practice because it can lead to severe skin irritation, chemical burns, and even permanent scarring. Without proper diagnosis, attempting to remove a mole at home can also result in missing signs of skin cancer or other medical concerns. Experts stress the importance of getting any skin growth evaluated by a medical professional before attempting removal. Home remedies may seem natural and harmless, but they lack the precision and safety of professional treatment.
The Rise of Dangerous Trends and the Need for Awareness
Part of the appeal of DIY hacks is the promise of saving time and money while feeling in control of one’s appearance or home. However, the internet rarely shows the aftermath of a hack gone wrong. Experts from various fields are urging the public to think critically before trying any health, beauty, or repair advice found online. Professional training exists for a reason, and in many cases, skipping that expertise can lead to long-term damage or serious injury. What might start as a five-second clip could end in a trip to the hospital or thousands of dollars in repair costs.
