The danger zone under your nose: why popping pimples in the 'triangle of death' can put you at risk

Influencer Chelsea Delgado’s experience highlights the so‑called 'triangle of death'—the area from the bridge of the nose to the corners of the mouth—where popping a pimple can allow bacteria to travel to the cavernous sinus, risking cavernous sinus thrombosis, stroke or meningitis. After squeezing a nose blemish, she developed swelling that spread to her eye and required a seven‑day course of antibiotics. While the overall risk in the US is rare (about 0.2–0.5 per 100,000 people per year), it’s a medical emergency if infection spreads. Experts advise not to pop zits in this zone, instead cover with hydrocolloid patches, use benzoyl peroxide or salicylic acid, apply a warm compress, and seek urgent care if fever, severe headaches, eye swelling, vision changes, or confusion occur. Delgado recovered with treatment, underscoring the real danger behind a common beauty habit.

Salmon-DNA injections and other odd beauty trends, demystified

Social-media beauty trends range from salmon sperm DNA injections to nightingale-droppings facial masks and PRP ‘vampire facials.’ Science suggests purified fish DNA fragments and growth-factor–rich plasma may modestly improve hydration, texture and wrinkles, but evidence is limited and often industry-funded. Experts caution against DIY uses of bird droppings and emphasize that real benefits come from proven routines (sunscreen, moisturisers, retinol) while researchers explore collagen optimization and microbiome–based therapies.

Why Over-50s Might Benefit From Cutting Back on Daily Showers

Why Over-50s Might Benefit From Cutting Back on Daily Showers

Dermatologists say skin tends to dry out and thin with age, so daily showers aren’t always ideal for those over 50. Shower frequency should depend on sweat, body odor, and climate, with recommendations ranging from about two to three times a week for dry skin to twice daily in hot, humid weather for the active; on non-shower days, spot-cleaning the underarms and groin is fine. Use short, lukewarm showers with gentle, fragrance-free soap (bar soap can be harsh), and moisturize daily to lock in moisture as you age.

Why Aging Odor Happens—and How to Minimize It

Why Aging Odor Happens—and How to Minimize It

A real aging odor is produced by 2-nonenal, a fatty aldehyde whose production increases with age as skin antioxidant defenses decline, sebum changes, and environmental stress accumulate; the scent typically appears after age 40 and is more noticeable in the 50s, though it varies by genetics, skin type, and lifestyle. It clings to skin and fabrics and isn’t easily washed away, and while some people may not notice it themselves due to olfactory adaptation, there’s no proven cure. Experts suggest skincare with antioxidants and practices that reduce aldehyde persistence (like certain tannin-containing cleansers) and careful laundering to minimize the odor, framing aging as a natural change rather than a hygiene problem.

Why the ‘Old-Person Odor’ Happens—and How to Manage It

Researchers confirm the so-called 'old person smell' is real and rooted in 2-nonenal, an aldehyde whose production increases with age—typically after 40 and more noticeable in the 50s and beyond. The scent varies by genetics, skin type, lifestyle, and environment, and it lingers on skin and fabrics, not easily washed away. While no proven cure exists, dermatologists suggest antioxidant-based cleansers and products that bind aldehydes, along with good skincare and laundering practices to minimize it. The smell is subjective and may be perceived differently, and aging should be viewed as a natural process rather than a sign of poor hygiene.

The Science Behind 'Old Person Smell' and Ways to Minimize It

The so-called 'old person smell' is real and stems from the aging skin producing more of the aldehyde 2-nonenal, a change driven by factors like reduced antioxidant defenses, altered sebum, and increased environmental damage. Production typically rises after age 40 and varies by genetics, skin type, and lifestyle; some people may not smell it themselves due to olfactory adaptation. There’s no proven cure, but skincare with antioxidants, laundering practices, and certain odor-binding agents may help reduce persistence, with research exploring future approaches such as tannin-containing soaps and eggplant extracts.

Black Ginseng Shows Molecular Promise in Slowing Inflammatory Skin Aging

Black Ginseng Shows Molecular Promise in Slowing Inflammatory Skin Aging

New research indicates black ginseng extract (BGE), rich in rare ginsenosides formed during processing, may counter inflammation-driven skin aging by reducing MMP-1 expression and prostaglandin E2 while increasing TIMP-1 in human fibroblasts and a 3D skin model; docking studies suggest ginsenosides Rg3, Rg5, and RK1 bind to inflammation- and aging-related proteins, highlighting BGE’s potential as a cosmetic/dermatology ingredient to preserve collagen and skin structure. Further work is needed to fully map the pathways involved.

Large Review Finds Oral Collagen Can Improve Skin Firmness and Hydration

An umbrella review of 16 systematic reviews and 113 randomized trials (nearly 8,000 participants) shows that oral hydrolyzed collagen supplements are associated with firmer, more hydrated skin, with stronger effects the longer you take them, and may also reduce osteoarthritis symptoms and support muscle/tendon structure; however, benefits are modest and not a cure, and collagen should complement—not replace—good skincare and sun protection.

Scalp Massagers Can Support Hair Health, Experts Say

Experts say scalp massagers aren’t a miracle cure for hair growth, but they can help by boosting blood flow, exfoliating buildup, and improving the scalp environment when used as part of a broader treatment plan. Use gentle, silicone-bristle tools and massage about 15 minutes, three times a week (usually before shower), then wash and apply a scalp serum. Results vary, with studies showing modest benefits and a variety of hair-growth treatments often recommended alongside massaging.

Midlife Hormonal Acne: Menopause Reopens the Skin Battle

During perimenopause and menopause, hormonal changes can trigger acne in midlife—often on the chin and jawline—even for women who’ve been clear for years. Treatments are typically hormonal (spironolactone, birth control, or hormone therapy) plus topical retinoids or antibiotics, with isotretinoin for more severe cases. Lifestyle steps like adequate sleep, stress management, non-comedogenic skincare, and proper cleansing help; if OTC products fail after about two months, see a dermatologist. Acne often improves after menopause, though evidence on GLP-1 medications and acne remains inconclusive.

Ketosis-Linked Rash: A Rare Keto Diet Side Effect

A NEJM case report describes a 20-year-old man who developed prurigo pigmentosa, or 'keto rash,' after starting a keto diet; the itchy, net-like rash appeared on the neck and chest, is extremely rare (about 300 documented cases worldwide as of 2019), and typically resolves once ketosis ends, with treatment usually involving stopping ketosis and sometimes tetracycline antibiotics.

Expert Insights on Collagen Supplements for Aging Skin

Despite the popularity of collagen supplements for aging skin, scientific evidence does not strongly support their effectiveness, and they are not currently recommended by dermatologists. Natural ways to support collagen include a healthy diet rich in protein and vitamin C, sun protection, and avoiding smoking, which are more proven methods to maintain skin health.
