Dermatologists warn that melanotan II, a banned injectable/nasal tanning drug sold online and promoted by TikTok influencers, poses serious risks (including priapism), offers no proven sun-protection, can darken or alter moles, and may be linked to melanoma; experts urge regulation and caution amid widespread misinformation.
Dermatologist Dr. Michelle Henry stresses her own routine of monthly self-checks, scalp inspections with help from a hairstylist, and photo comparisons to spot melanoma and other skin cancers early. She watches for the ABCDE signs, ugly-duckling moles, nail streaks, and changes in new or existing spots, while advocating sunscreen use and new UVA-covering options like Bemotrizinol to improve prevention.
Dermatologists say the most commonly missed early sign of skin cancer is a new pigmented spot that looks like a mole or freckle. Changes in existing moles matter, but a new lesion can be the first clue, so see a dermatologist if you notice one. Protect your skin from UV exposure with SPF 50+ and protective clothing, especially during peak sun hours. A family history or fair skin increases risk, so annual (or higher-risk) skin checks are advised. Early detection dramatically improves melanoma survival (about 99% five-year survival when caught early, vs. 68% after it has spread).
Minoxidil remains effective but requires ongoing use and can cause scalp irritation or unwanted facial hair; experts review alternatives such as low-dose oral minoxidil, mesotherapy, rosemary oil, copper peptides, low-level laser therapy, PRP, saw palmetto, microneedling, ketoconazole shampoo, caffeine-based products, stem-cell therapies, and Regenera activa. These options often work best as part of a multi-modal plan that supports scalp health and the follicle environment rather than replacing minoxidil outright. Always consult a clinician for personalized guidance, and be aware of safety considerations like hormonal effects and pet toxicity from topical minoxidil.
Rosacea is a chronic inflammatory skin condition that can cause redness, flushing, acne-like breakouts, visible blood vessels, and sensitivity (and can include ocular symptoms). While there is no cure, symptoms are manageable through a rosacea-friendly skincare routine (gentle cleansing, moisturizer, sunscreen) and targeted treatments such as topical azelaic acid, benzoyl peroxide, and antibiotics; vasoconstrictors like brimonidine or oxymetazoline can reduce persistent redness; laser or intense pulsed light therapy can improve flushing; ivermectin may help reduce Demodex mites; and isotretinoin or surgery may be needed for thickened skin. Triggers vary by person but commonly include heat, cold, sun, spicy foods, alcohol, and exercise, with makeup or medications also potentially contributing. Ocular rosacea (eye symptoms) is managed with warm compresses, eyelid hygiene, and sometimes antibiotic eye drops. Diagnosis is made clinically by a dermatologist.
A PLOS Digital Health study analyzed the 971 most-viewed sunscreen videos on TikTok in Sept 2024 and found widespread sunscreen misinformation—claims that ingredients are toxic or endocrine disruptors—though researchers note no evidence that common sunscreen ingredients are harmful; about 86% of videos promoted sunscreen, 6% critiqued it, and 7% were neutral, while misinformation appears to drive engagement; dermatologists warn that public sun-safety knowledge is weak, with quizzes showing many Americans struggle to protect themselves from sun damage.
A University of Alberta study of nearly 1,000 TikTok sunscreen videos found that while most content promotes sun protection, the most engaging posts spread misinformation—including claims about vitamin D deficiency, cancer, and toxins. Researchers note both chemical and mineral sunscreens are regulated by the FDA, debunk various myths, and urge viewers to be cautious of influencer-driven health claims and to rely on scientific consensus.
Howie Mandel reveals that as a child a sand fly laid larvae under his skin, an ordeal that was worsened when doctors publicly displayed him at a Toronto dermatology convention. The traumatic experience and painful treatments contributed to his lifelong OCD and germophobia, highlighting the need for empathetic, patient-centered care and self-advocacy in medical settings.
Collagen naturally declines with age, starting in your 20s and accelerating in later decades, and is further degraded by sun exposure, pollution, smoking, and high sugar intake. To support it, commit to daily SPF 30+, use retinoids, antioxidants, and peptides, and favor vitamin C–rich foods to aid collagen formation; note that topical collagen cannot penetrate deeply. Oral collagen supplements (like Verisol) may improve skin quality for some people, but results vary. For deeper results, dermatology treatments such as chemical peels, lasers, microneedling (often with PRP), radiofrequency or ultrasound devices, and biostimulating fillers can stimulate new collagen. A combination of sun protection, effective actives, nutrition, and appropriate in-office procedures offers the best path to firmer, more youthful-looking skin.
A 23-year-old Florida woman developed whip‑mark–like red streaks on her back two days after eating shiitake mushrooms. Doctors diagnosed shiitake dermatitis, a rare inflammatory skin reaction linked to lentinan in the mushroom, with risk possibly influenced by how the mushrooms are grown. She received a topical steroid, an antifungal, and antihistamines/corticosteroids; the rash resolved in about three weeks, and she continued consuming shiitake mushrooms without recurrence.
Five dermatologists say collagen supplements aren’t a miracle cure for skin: while some evidence hints at skin-health benefits and joint support, oral collagen may not directly deposit collagen in the skin, and results are generally modest at best. Benefits depend on consistent use and individual biology, and supplements should complement—not replace—a solid skincare routine, SPF, and a healthy diet. Choose well‑formulated brands and be mindful of additions like biotin and animal-sourced ingredients, especially if you have vegan or thyroid considerations.
RFK Jr. pulled the FDA’s long-delayed proposal to ban minors from using tanning beds and require risk disclosures, prompting disappointment from dermatologists who warn that indoor tanning delivers concentrated UV radiation and raises melanoma risk. The WHO classifies tanning beds as a Group 1 carcinogen, and while many states already restrict youth access, the federal rule is paused to reconsider, leaving a patchwork of protections in place.
A 15-year-old in Nepal developed five large, rubbery keloids that erupted from chickenpox scars—a rare outcome called eruptive keloids documented in a case report—treatment is difficult and she chose to manage symptoms rather than pursue aggressive therapy; vaccination remains the best protection against varicella.
Celebrities are reportedly turning to a 'Hollywood dose'—tiny, controlled amounts of isotretinoin (Accutane)—to keep skin smooth, shrink pores and even banish rosacea without surgery. Dermatologists say microdosing is an off‑label practice long used for acne, with regimens far lower and longer than standard courses. While it may boost collagen and improve texture, it carries serious risks (including birth defects if pregnancy occurs, mood effects, liver and cholesterol changes), so strict medical monitoring and counseling are essential.
The Washington Post explains that common warts—caused by HPV and often appearing on hands, feet, or face—can often be treated at home with various remedies, including the widely discussed duct-tape method, while dermatologists note that effectiveness varies and persistent or painful warts should be evaluated by a clinician.
