A surprising new look at tattoos and skin cancer is turning the usual cautionary tale on its head. In a large population-based study conducted in Utah, researchers found that people with two or more tattoos showed a lower associated risk of melanoma than those with none or just one tattoo. The strongest signal appeared in individuals with four or more tattoos. Yet the researchers were quick to caution that this is far from a verdict that tattoos protect against skin cancer. The pattern likely reflects unmeasured factors—such as sun-safety behaviors and other health-conscious choices—not a direct protective effect from ink.

A large wave of new evidence is adding to the chorus of dermatologists recommending nicotinamide, a form of vitamin B3, as a daily supplement to help prevent new skin cancers in people at high risk. In a growing body of research, this common dietary ingredient—already familiar to many as a multivitamin staple—appears to reduce the number of new skin cancer cases when taken regularly over time. The findings come amid a broader push in public health to combine everyday wellness habits with proven medical prevention strategies, a message that resonates deeply in sun-soaked Thailand where outdoor work and cultural gatherings intensify UV exposure.

A new analysis of nearly 34,000 U.S. veterans suggests that taking nicotinamide, a widely available form of Vitamin B3, is linked to a meaningful reduction in non-melanoma skin cancers among people who have already had skin cancer. The biggest benefit was seen in those who started the supplement after their first cancer diagnosis. Participants who took 500 mg of nicotinamide twice daily for at least one month experienced about a 14% overall reduction in future skin cancers, with a striking 54% risk drop among those who began after their initial cancer. The cancers most affected were basal cell carcinoma and squamous cell carcinoma, the two most common non-melanoma forms. Importantly, the study did not assess melanoma.

A wave of new research summarized in recent reviews suggests that oral hydrolyzed collagen can offer modest improvements for skin ageing, including better elasticity, hydration, and a reduction in wrinkle depth after several weeks of use. The debate between marine collagen and plant-based collagen has sharpened as consumers increasingly seek “clean” beauty solutions that promise visible results. The current consensus from the best available evidence is nuanced: marine-derived collagen tends to show higher bioavailability and somewhat stronger skin benefits in many studies, while plant-based options are often marketed as collagen boosters that support the body’s own collagen production rather than delivering actual collagen peptides themselves. For Thai readers, this matters not only for personal health choices but also for the wider national conversation about wellness, ageing, and consumer protection in a fast-growing market for dietary supplements.

A recent magazine feature asked a provocative question: should you take vitamins for better skin? While fashion and beauty outlets often promise dramatic improvements from pills, the latest science suggests a more nuanced story. For most people, the strongest skin benefits come from proven skincare techniques and a balanced diet, rather than relying on high-dose vitamin supplements alone. The implications are especially relevant for Thai readers who live in a sun-rich climate and navigate a bustling market of wellness products. In short, vitamin pills can play a role in addressing true deficiencies, but they are not a miracle cure for clear, youthful skin.

A landmark study from a leading health institute shows that beta HPV, a common skin virus, can directly drive skin cancer in individuals with severely weakened immune systems. Published in a top medical journal, the findings reshape our understanding of how some skin cancers develop and underscore the need for vigilant monitoring among at-risk groups. For Thai readers, the research aligns with rising non-melanoma skin cancer rates and increasing use of immunosuppressive therapies in the region.

A groundbreaking study from the National Institutes of Health in the United States has confirmed for the first time that a form of human papillomavirus (HPV) commonly found on the skin—beta HPV—can directly cause skin cancer in individuals with severely weakened immune systems. The findings, published recently in the New England Journal of Medicine, have significant implications for how some skin cancers may develop and reinforce the importance of vigilant health monitoring in immunocompromised populations. For Thai readers, this development is particularly relevant given the rising rates of both non-melanoma skin cancer and immunosuppressive conditions in the region.

A new wave of concern is sweeping through the pediatric health field following the publication of research in Environmental Health Perspectives, which found that children with double the urinary triclosan levels had a 23 percent higher likelihood of experiencing eczema symptoms. Triclosan, a chemical once widespread in antibacterial soaps and body washes, was restricted in the United States nearly a decade ago. However, evidence suggests it persists in everyday products worldwide — including in Thailand — with the potential for ongoing health impacts, particularly among vulnerable young populations (Washington Post).

A recent study in Environmental Health Perspectives raises fresh concerns about triclosan, a chemical once common in antibacterial soaps and some toothpaste. The research indicates that children with higher urinary triclosan levels are more likely to show eczema symptoms. While the United States banned triclosan in most consumer wash products nearly a decade ago, the compound remains in some items worldwide, including in Thailand, highlighting ongoing risks for vulnerable children.

A surge of collagen products has flooded Thai shelves, from colorful injections in beauty clinics to powders and drinks in markets. Consumers are weighing ingestibles and innovative procedures like NeoGen plasma therapy. But do collagen shots and supplements truly restore youth, or are the gains mostly superficial? New reviews offer cautious signals, urging Thai shoppers and clinicians to tread carefully.

Thailand’s beauty market mirrors global trends, propelled by social media and celebrity endorsements. In Bangkok, clinics promote collagen as a remedy for sagging skin, fine lines, and a dull complexion. With an aging population and a cultural emphasis on youthful appearance, demand for new beauty innovations remains high. Yet scientists warn that the journey from swallowing collagen to visibly younger skin is not straightforward.

The promise of youthful, radiant skin in a bottle has led to a surge of collagen-based products in Thailand, from colourful shots on beauty shelves to powdered supplements at local markets. As Thais increasingly turn to these products—and to innovative medical procedures such as plasma-based NeoGen treatments—the question arises: do collagen shots and supplements live up to the hype? Or are their benefits merely skin-deep? Recent research, including a critical review summarized in The Guardian, brings both hope and skepticism to the collagen conversation and raises important points for Thai consumers and health professionals.

Recent coverage in Vogue and the latest dermatological studies suggest that vitamin A might be the missing piece for those struggling with dry, brittle strands, itchy scalp, or unexpected hair loss. With experts increasingly linking micronutrient intake to hair health, emerging evidence reveals that vitamin A’s impact on the scalp and follicles could explain everyday hair complaints—an issue with both global and Thai resonance due to shifting nutritional patterns and high humidity levels in the kingdom.

Hair health is linked to nutrition, and new findings on vitamin A shed light on scalp health and growth. For Thai readers facing humid weather and evolving dietary habits, understanding vitamin A helps people make informed choices without overdoing supplements.

In Thai culture, healthy hair symbolizes wellness and beauty, from weddings to daily grooming. The growing interest in vitamin A comes as many Thais seek nutrition-based solutions amid social media influence and a rising market for supplements. Clinicians emphasize balance, noting vitamins interact with the body’s hair biology.

As Thailand braces for another sweltering summer, a growing international trend has caught the attention of both beauty enthusiasts and health experts: applying deodorant not just to armpits, but to various body areas prone to sweat and odor. A recent discussion in Slate, reflecting personal experiences with using spray deodorant on clothes and across the body, prompts the question—should Thais embrace this expanding application, and is it safe?

The growing popularity of “whole-body deodorants” is more than a passing fad. Major brands such as Dove and Lume have rolled out products specifically marketed for use on more sensitive or “non-traditional” areas—feet, the back, under the breasts, and even the groin—claiming satisfaction and safety for users seeking comprehensive odor control (CNN, Rolling Stone). This shift follows changing consumer hygiene habits in the global north, with the United States seeing a spike in sales of such products since 2024 (Forbes).

A hotter season is on the horizon in Thailand, and a growing trend is catching attention: deodorants designed for use beyond the armpits. Thai readers wonder about safety and practicality in humid climates when applying deodorant to clothes or other body areas.

Whole-body deodorants target areas such as feet, back, under-breasts, and groin, promising broader odor control. Brands highlight dermatological testing and safety, but experts warn that not every product suits every skin area. In the United States, multipurpose deodorants have gained momentum since 2024, reflecting a shift in personal care habits.

A breakthrough study has found that Vitamin C, long celebrated for its role in immune health, may also target visible signs of skin aging and help the skin appear noticeably younger. This discovery, published in the Journal of Investigative Dermatology and recently highlighted in an AOL report, could reshape how Thai readers approach both their diets and skincare routines as they seek to maintain youthful, healthy skin (AOL).

As Thai society places a strong cultural emphasis on appearance, health, and wellness, the relevance of this research is clear. Skin health has moved beyond simple cosmetics, with younger generations valuing evidence-based strategies for maintaining their appearance as part of a holistic lifestyle. Interest in accessible, natural approaches that can be incorporated into daily life — especially in a country rich in fresh produce — has never been higher.

A new study suggests Vitamin C can support healthier skin by promoting stronger, more resilient epidermal layers. The research, published in a leading dermatology journal and summarized by major outlets, invites Thai readers to consider how diet and skincare work together for lasting skin health.

In Thai culture, appearance and well-being are closely connected to daily life. Skin health now blends science with routine practices, as people seek practical, natural approaches that fit busy schedules and Thailand’s abundance of fresh produce.

A new Japanese study suggests vitamin C can counter age-related thinning of the skin by activating key “youth genes,” offering promising implications for healthy aging and skin resilience in Thailand. Published in the Journal of Investigative Dermatology, the research indicates vitamin C acts beyond its antioxidant role, influencing gene activity to strengthen the skin’s inner layers. This marks a molecular step toward longer-lasting skin health for Thai readers who value practical, science-backed options.

A groundbreaking Japanese study has revealed that vitamin C can help reverse age-related thinning of the skin by activating so-called “youth genes,” offering hope to many Thais concerned about healthy aging and skin rejuvenation. This research, published in the Journal of Investigative Dermatology on April 20, 2025, demonstrates for the first time that vitamin C works at the genetic level to promote thicker, healthier skin in ways that extend beyond its antioxidant reputation and traditional beauty claims (sciencedaily.com).

Exercise can be healthier for people with eczema than it seems. New research and expert guidance show that activity is still possible with proper preparation. Global estimates put atopic dermatitis affecting about 245 million people, with up to 10% of Thai children affected. This makes safe, enjoyable exercise a matter of everyday well-being across Thailand.

Thailand’s tropical, humid climate makes eczema management during activity particularly relevant. Eczema, or atopic dermatitis, is a long-term skin condition marked by itching, redness, dryness, and sometimes blisters or thickened skin. It often begins in childhood and is influenced by genetics and the immune system. Sweat, heat, and friction can trigger flare-ups, but exercise offers significant mental and physical health benefits. The message from researchers and clinicians is clear: don’t abandon activity; sweat smart.

Staying fit with sensitive, easily irritated skin might sound like an Olympic challenge, but new research and expert advice show that people with eczema can still reap the rewards of exercise—if they sweat-smart. With atopic dermatitis now affecting an estimated 245 million people globally and up to 10% of Thai children according to global epidemiological data (Wikipedia: eczema), the question of how to safely integrate exercise into daily life has real consequences for personal health and quality of life across the country.

Honey has become a popular natural option for cleansing the face, promoted for its moisturizing, healing, and brightening effects. In Thailand, raw and manuka honey are widely discussed in beauty blogs and clinical conversations for their antibacterial and antioxidant properties. But do the science and local experiences align, and what should Thai consumers consider before making honey part of their daily routine?

Honey has deep roots in traditional healing, including traditional Thai medicine, where it is valued for skin care and wound healing. The global wellness movement has amplified interest in natural ingredients, making honey a staple in DIY masks and store-bought products. While Western dermatology and Asian skincare traditions reference honey’s benefits, Thai consumers rightly ask whether honey lives up to the hype and if it suits all skin types.

In the quest for natural skin care, honey has emerged as a popular household remedy, touted as a gentle facial cleanser that promises to moisturize, heal, and brighten skin. From beauty blogs to dermatologist offices in Thailand, raw and manuka honey are praised for their antibacterial and antioxidant powers. But are these claims backed by science, and are there risks consumers should weigh before adopting honey as part of their daily facial routine?

A fresh wave of research into collagen supplements has sparked considerable debate, questioning the true benefits these products offer for skin and joint health. With Thais increasingly turning to collagen powders, capsules, and drinks promising firmer skin and pain-free movement, the latest evidence raises important questions about whether these popular supplements deliver on their bold claims—or if they’re just another fleeting consumer trend.

Collagen is the most abundant protein in our body, forming a crucial structure for our skin, bones, and joints. As we age, collagen production naturally declines, leading to wrinkles, loose skin, and joint discomfort—ailments that many Thai people, especially those over 40, are eager to combat. It’s common to see collagen products on pharmacy shelves across Thailand, from Bangkok malls to local markets. But does popping a collagen capsule or sipping a strawberry-flavored collagen drink actually slow the aging process or ease joint pain?
