At Moyem, we believe beauty is the natural result of inner balance and long-term health.

For many people, one oft-neglected yet powerful ally in this journey is vitamin D, a longevity signal for your skin, hair and body.

Vitamin D and Cellular Aging

Recent findings from the Harvard-led VITAL Study (VITamin D and omegA-3 triaL) have highlighted vitamin D’s role in slowing biological aging.

Women and men aged 50+ who took 2,000 IU of vitamin D3 daily experienced significantly less telomere shortening—a marker of cellular aging—compared to those on placebo. This preservation equated to roughly three years of delayed biological aging.

Omega-3 fatty acid supplementation had no significant effect on telomere length throughout follow-up.

What Are Telomeres?

Telomeres are protective caps at the ends of our DNA (like the plastic tips on shoelaces that prevent fraying), and they shorten as we age. When they become too short, cells lose their ability to function and regenerate (i.e. biological aging), impacting everything from immune health to age-related diseases to skin aging and hair loss.

Vitamin D appears to buffer this process by reducing oxidative stress and chronic inflammation.

Skin-Deep Benefits of Vitamin D

Working at the DNA level, Vitamin D is a key regulator of skin and hair health. It is involved in:

• Skin cell growth and turnover: Promotes youthful differentiation of keratinocytes and supports skin barrier function.
• Repair and wound healing: Helps modulate inflammation and supports recovery from daily environmental damage and procedures.
• Protection against photo-aging: Regulates oxidative stress and helps guard against accelerated collagen breakdown and irregular pigmentation.
• Anti-inflammation action: Particularly beneficial in skin and scalp conditions like psoriasis, eczema, rosacea, acne and alopecia areata, where inflammation undermines skin quality and immune system regulation.
• Hair follicle cycling: Hair follicles are very metabolically active and hence, highly reactive to nutritional, hormonal and inflammatory signals. Adequate vitamin D is required to stimulate transition into the active growth (anagen) phase.

Without adequate vitamin D, skin may appear dry, dull or inflamed, and healing after treatments may be slower or less efficient. Diffuse hair thinning and/or shedding are also common presentations. All visible cues that biological aging is accelerated.

What This Means for You

As we age, the skin’s ability to synthesize vitamin D from sunlight naturally declines. Coupled with indoor living, diligent sun protection, and darker Asian skin tones, suboptimal vitamin D levels have become highly prevalent, even in our sunny climate.

Whether you’re focused on graceful aging, hormone balance, or getting the best aesthetic outcomes from your skin and hair treatments, replenishing vitamin D is a smart, evidence-based step. We recommend:

• Periodic vitamin D testing (a simple blood test) to ensure optimal—not just “normal”—levels.

• Regular safe sun exposure (without sunscreen for 10–15 minutes, depending on your skin tone and location).

• Supplementing under professional guidance if needed (especially because we are mostly indoors).

Healthy longevity and ageless, resilient skin all begin at the deepest level—our cells. Optimising your vitamin D status is one of the simplest, yet profound ways to protect your cellular vitality and radiant youth.
