While social media may promote quick-fix skincare solutions, Lamelle experts caution that misinformation can cause lasting harm.
Trained therapists offer science-backed treatments that online advice simply cannot match.
Misinformation and self-treatment risks
From DIY masks to at-home microneedling kits, the internet is overflowing with skincare advice. But as easy as it seems, the risks are high. Many online tips lack scientific backing, and without a proper understanding of your skin, you could end up making your condition worse.
“Unfortunately, what we see online are practices that ignore basic dermatological science,” explains Dr. Bradley Wagemaker, Medical Director at Lamelle Research Laboratories. “The skin is a living organ with a finely balanced barrier system. When you apply harsh, untested remedies, you risk stripping away that protection, opening the door to infection, irritation, and long-term damage.”
Unverified remedies, aggressive acids, or untested products can cause burns, infections, or permanent scarring. One of the biggest culprits is at-home microneedling. “Microneedling is a powerful tool in trained hands,” Dr. Wagemaker says. “But in untrained hands, the risk of trauma, pigmentation, and infection far outweighs any short-term benefit. Professional sterilisation, depth control, and aftercare are non-negotiable.”
Viral DIY skincare gone wrong: real-world cases
- Baking soda burns and metabolic risks
Despite viral claims, studies show bicarbonate paste does not relieve psoriasis or nappy rash. Instead, it has caused deep chemical burns and, in babies, even life-threatening hypokalaemic metabolic alkalosis. “Baking soda belongs in your kitchen, not on your skin,” notes Dr. Wagemaker. “It completely disrupts the skin’s natural acid mantle, which is critical for protecting against pathogens.” - Garlic: ancient remedy, modern irritant
Promoted online as a “natural antibiotic,” raw garlic has triggered dermatitis and even third-degree burns. “Just because a plant has beneficial compounds in a laboratory doesn’t mean you can rub it directly onto your skin,” Dr. Wagemaker stresses. “A trained therapist will help you access those benefits safely through clinically formulated extracts.” - The “acid challenge” gone viral
TikToker Stephanie Margarucci (Beasteater) appeared with blistered cheeks after using an expired product. Attempting to steam the burns worsened the damage, spreading infection into her bloodstream. “Expired or misused acids are particularly dangerous,” says Dr. Wagemaker. “Without guidance, you can cause chemical burns in minutes.” - DIY injections with hyaluronic acid
One patient injected an over-the-counter serum into her cheeks after watching a YouTube tutorial, resulting in infection and scarring. “Self-injecting is never safe,” warns Dr. Wagemaker. “Even qualified doctors undergo years of training to master dermal fillers. Attempting it at home is reckless.” - Household cleaners as ‘skincare’
A South African woman burned her face after applying Handy Andy mixed with spirits. “This is one of the most extreme examples of misinformation,” Dr. Wagemaker says. “Household detergents are corrosive. A therapist or dermatologist would never endorse such practices.”
Why a trained skin therapist matters
Unlike the one-size-fits-all recommendations online, professionally-trained skin therapists offer highly personalised guidance.
“A therapist is not just someone who sells products,” Dr. Wagemaker explains. “They are a translator of science — helping you understand your skin’s needs, teaching you how ingredients work, and guiding you through safe treatment plans that evolve as your skin changes.”
Key advantages of professional guidance:
- Education with evidence-based practices – separating myths from science.
- Personalised treatment plans – tailored to your history, skin type, and lifestyle.
- Ongoing monitoring – so your regimen adapts safely over time.
- Ingredient expertise – ensuring actives like retinoids, Vitamin C, or acids are combined safely.
Science, not hype: Active ingredients that work
Instead of investing in every trending product, therapists emphasise proven actives in safe concentrations.
“Ingredients like Vitamin C, niacinamide, retinoids, and peptides all have a place in skincare,” Dr. Wagemaker notes. “But dosage, stability, and formulation are critical. The wrong form of Vitamin C can irritate. Combining the wrong acids can inflame. Therapists ensure you reap the benefits without the risks.”
The bottom line
The rise of online beauty culture has blurred the line between marketing and medicine. While social media offers inspiration, skin therapists provide the personalised, science-driven care that trends can’t deliver.
“Your skin is not a playground for experiments,” concludes Dr. Wagemaker. “It’s your body’s largest organ, and it deserves the same respect as your heart or lungs. When in doubt, trust trained professionals — not TikTok.”
