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.

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 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 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).

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.

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?

The debate over whether premium-priced or budget-friendly vitamin C serums deliver optimal skin benefits continues to captivate skincare enthusiasts globally. A recent review by Wirecutter, highlights intriguing aspects that explain the stark price disparities between products, while offering recommendations in both categories.

Vitamin C, often revered for its skin-brightening and anti-aging properties, presents formulation challenges due to its notorious stability issues. This stability influences the efficacy of the serum, as noted by dermatologist Mina Amin. A prime example is the high-end SkinCeuticals C E Ferulic, distinguished by its patented stabilization method which enhances both solubility and longevity of the active ingredients. Senior staff writer Rory Evans describes vitamin C as a “diva ingredient,” requiring specific conditions for optimal absorption and effectiveness.
