The short answer: dry, flaky winter skin is most often linked to low vitamin D, along with shortfalls in vitamin A, vitamin E, and essential fatty acids (omega-3s). These nutrients help your skin build a healthy barrier and hold onto water, so when they run low, moisture escapes faster and rough, tight patches appear. That said, a “deficiency” is rarely the whole story in Southern California.
Here in Huntington Park and across the Gateway Cities, our winters aren’t snowy, but the season still brings dry heat, cooler nights, indoor air conditioning and heating, and the odd gusty Santa Ana stretch that pulls moisture straight out of your skin. Below, our estheticians break down which vitamins actually matter, how to spot a real deficiency versus everyday dehydration, and what to do about it.

The Vitamins Most Linked to Dry Winter Skin
No single vitamin controls your skin on its own, but a handful do the heavy lifting when it comes to hydration and barrier strength. If your skin turns dry and dull every winter, these are the usual suspects:
- Vitamin D: Southern California is sunny, but shorter winter days, more time indoors, sunscreen (which you should still wear), and naturally deeper skin tones all lower how much vitamin D your body makes. Low levels are commonly associated with dry, itchy, easily irritated skin.
- Vitamin A (and retinoids): Vitamin A helps skin cells turn over and mature properly. Too little can leave skin rough, bumpy, and flaky, especially on the arms and cheeks.
- Vitamin E: A fat-soluble antioxidant that lives in your skin’s oils and helps defend the barrier against dryness and environmental stress like smog and UV.
- Vitamin C: Essential for collagen and for a resilient barrier. Low levels can show up as rough, dry, easily bruised skin.
- B vitamins (especially B3/niacin and B7/biotin): Support the skin’s protective lipids. Niacin deficiency in particular is tied to rough, scaly patches.
- Essential fatty acids (omega-3s): Not a vitamin, but crucial. They are the raw material for the fats that keep water locked in. Low intake often means dry, flaky, itchy skin.
Deficiency or Just Dehydration? How to Tell the Difference
Before you assume you’re deficient in anything, it’s worth knowing that most winter dryness in our climate is environmental, not nutritional. True vitamin deficiencies do exist, but they usually come with more than a dry cheek.
Signs that point toward a possible deficiency (worth discussing with your doctor):
- Persistent dryness that doesn’t improve with a good moisturizer
- Cracking at the corners of the mouth, unusual fatigue, hair thinning, or slow-healing skin
- Rough, scaly patches that appear year-round, not just in winter
Signs it’s simple dehydration or barrier damage (very common here):
- Dryness that flares after AC, heaters, long hot showers, or a windy Santa Ana day
- Tightness that eases quickly once you apply a hydrating serum and cream
- Skin that looks better after a facial or a few days of gentler products
Only a blood test ordered by your physician can confirm an actual deficiency. As estheticians, our job is the outside layer, so if we suspect something nutritional, we’ll always suggest you check in with your doctor too.
Foods and Supplements That Support Skin From Within
The most reliable way to keep these nutrients topped up is through everyday food. A few skin-friendly, easy-to-find choices:
- Vitamin D: salmon, sardines, egg yolks, fortified milk and plant milks, and sensible sun exposure (with SPF on your face).
- Vitamin A: sweet potato, carrots, spinach, and eggs.
- Vitamin E: almonds, sunflower seeds, avocado, and olive oil, all easy to add to a taco or salad.
- Vitamin C: citrus, bell peppers, strawberries, and guava.
- Omega-3s: fatty fish, walnuts, chia, and flaxseed.
- Hydration: plenty of water, especially on dry-heat days when you may not feel thirsty but are still losing moisture.
Supplements can help if your doctor confirms you’re low, but more is not better with fat-soluble vitamins like A, D, and E, which can build up. Aim for a varied diet first, and treat supplements as a targeted fix rather than a daily default.
What Actually Fixes Dry Winter Skin (Inside and Out)
Nutrition sets the foundation, but your topical routine is what most people feel day to day. Here’s the barrier-first approach our team recommends through the cooler months:
- Cleanse gently. Swap foaming, stripping cleansers for a cream or gel that doesn’t leave skin squeaky. Skip very hot water.
- Layer humectants under occlusives. Apply a serum with hyaluronic acid or glycerin to slightly damp skin, then seal with a moisturizer containing ceramides, squalane, or shea butter.
- Use topical vitamins wisely. A morning vitamin C serum brightens and protects against smog and UV; a nighttime retinoid (vitamin A) supports renewal, just buffer it with moisturizer if you’re dry.
- Don’t quit sunscreen. Our winter sun is still strong. Daily SPF 30+ protects the barrier you’re working to rebuild.
- Exfoliate less, not more. Once or twice a week is plenty in winter. Over-exfoliating is a top cause of the very flakiness people try to scrub away.
Consistency beats intensity. A few well-chosen products used daily will do more than a cabinet full of actives.
How a Facial at Dazzling Helps Your Winter Skin
A professional treatment does what home care can’t: it deeply rehydrates, removes built-up dead cells without damaging the barrier, and infuses concentrated actives. At our Huntington Park studio, a few options are especially suited to dry, dull winter skin:
- Hydrating facial: our go-to for parched, tight skin. It floods the skin with moisture and calms redness from wind and dry heat.
- Multivitamin facial: a nutrient-rich treatment that layers in vitamins A, C, and E to support a stronger, more radiant barrier.
- Anti-aging facial: ideal if your dryness comes with fine lines and loss of bounce, since dehydration makes both look worse.
Many clients across Huntington Park, South Gate, Bell Gardens, and Commerce book a hydrating or multivitamin facial every few weeks through the winter to stay ahead of the dryness rather than chasing it. We’ll also assess your skin in person and send you home with a simple, realistic routine tailored to Southern California’s climate.

Frequently Asked Questions
Can a vitamin deficiency really cause dry skin?
Yes. Low vitamin D, A, E, C, or B vitamins, plus low omega-3 intake, can all weaken the skin barrier and lead to dryness. However, a true deficiency usually comes with other symptoms and should be confirmed by your doctor with a blood test.
Is my winter dryness from a deficiency or the weather?
In Southern California it’s most often environmental: indoor heating and AC, hot showers, and dry, sometimes windy Santa Ana days pull moisture from the skin. If a good hydrating routine clears it up quickly, it’s likely dehydration, not a deficiency.
Which facial should I book at Dazzling for dry winter skin?
Start with our hydrating facial for deep moisture, or a multivitamin facial if you want a nutrient boost of vitamins A, C, and E. You can book online at our Huntington Park studio and we’ll tailor the treatment after seeing your skin.
Do I need supplements to fix dry skin?
Not usually. A varied diet with fish, nuts, avocado, and colorful produce covers most skin-supporting nutrients. Only take supplements if your doctor confirms you’re low, since fat-soluble vitamins like A, D, and E can build up if overdone.
