Skincare & Sunshine: How Vitamin D Impacts Your Skin from the Inside Out

My Skin Was Glowing—Then Winter Hit

I remember this clearly: late summer, my skin looked great. Radiant, clear, hydrated. But as soon as fall arrived and the days got shorter, things changed. My skin became dull and dry. No matter how many serums or moisturizers I used, I couldn’t seem to get back that healthy summer glow.

After some trial and error, and a bit of research, I realized the missing piece wasn’t on my skincare shelf—it was internal. I was low on vitamin D.

The Link Between Vitamin D and Skin Health

Vitamin D is often praised for its role in bone health, but its effects on the skin are just as important. While most skincare routines focus on external application, true skin wellness starts from within—and vitamin D plays a powerful role.

Why Are We Low on Vitamin D?

• Lack of Sun Exposure: Our bodies produce vitamin D when exposed to sunlight. But sunscreen (essential for UV protection), long office hours, and living in northern climates limit our sun time.

• Seasonal Changes: In fall and winter, UVB rays are often too weak to trigger vitamin D production.

• Diet Gaps: Most diets don’t naturally include enough vitamin D unless you eat fatty fish regularly or consume fortified foods.

How Vitamin D Supports Healthy Skin

Here’s how this essential vitamin works from the inside out:

1. Promotes Skin Cell Growth and Repair

Vitamin D supports the creation of new skin cells and helps repair damaged skin. It plays a key role in maintaining the skin’s protective barrier, which helps prevent water loss and irritation.

2. Reduces Inflammation

Many skin issues—acne, eczema, psoriasis—are inflammation-related. Vitamin D helps regulate your immune system, potentially reducing flare-ups and calming redness.

3. Balances Sebum Production

Low vitamin D levels have been linked to excess oil production and acne-prone skin. With proper levels, your body is better equipped to maintain healthy sebum balance.

4. Improves Skin Tone and Radiance

Some people notice brighter, more even-toned skin when their vitamin D levels are optimized. That’s because healthy cell turnover and reduced inflammation contribute to a natural glow.

5. Supports Wound Healing

Vitamin D plays a role in how quickly your skin can heal from cuts, acne marks, or irritation. Deficiency may slow this process.

External Beauty Starts Internally

It’s easy to spend hundreds of dollars on creams, facials, and cosmetic procedures. But if your body is missing key nutrients—like vitamin D—your skin won’t reach its full potential, no matter what products you apply.

Vitamin D3 + K2: A Powerful Duo for Skin & More

While vitamin D3 is vital, it works even better when paired with vitamin K2. Why?

• K2 (MK-7) helps direct calcium to where it’s needed—like bones and teeth—and away from places it shouldn’t go, like your skin or blood vessels.

• The synergy between D3 and K2 promotes overall wellness, which indirectly supports clearer, healthier skin.

And because vitamin D is fat-soluble, it needs healthy fats for optimal absorption.

My Skin Routine Now Includes a Supplement

After realizing the connection, I added a vitamin D3 + K2 supplement to my morning routine—specifically, Infinitree’s Vitamin D3+K2 with Coconut Oil. Here’s why I love it:

• Contains 1,000 IU of D3 and 120 mcg of K2 (MK-7)

• Enhanced with organic coconut oil for better absorption

• Made in Canada in a GMP-certified facility

• Just one softgel a day—easy to take, hard to forget

Within a few weeks, I noticed my skin didn’t feel as tight or dry in the morning. My complexion looked brighter, and even during the coldest days, I didn’t need to over-layer my skincare.

How to Support Skin Health with Vitamin D3 + K2

✅ Step 1: Assess Your Lifestyle

• Do you get at least 10–15 minutes of sun daily?

• Do you eat fatty fish or fortified foods regularly?

• Do you experience dry skin, dullness, or frequent breakouts during colder months?

If yes, you might benefit from adding D3 + K2.

✅ Step 2: Choose the Right Supplement

Look for:

• D3 (cholecalciferol), not D2

• K2 as MK-7 for better bioavailability

• A fat-based carrier like coconut oil

✅ Step 3: Take It Daily

• Pair it with a meal containing fat

• Take it in the morning or midday for consistent energy

• Make it part of your skincare wellness checklist

Glowing Skin Starts from Within

Topical treatments are great, but don’t forget the nutritional foundation of skin health. Vitamin D3 and K2 won’t replace your moisturizer—but they might just make it more effective.

So if you’ve been layering on glow serums all winter and still not seeing results, maybe it’s time to look inward.
