Evidence-Based Protocol

Supplement stack ranked by research quality

Strong Evidence

Primary Stack (Tier 1)

Omega-3 Fatty AcidsA
2-3g EPA+DHA daily

Essential for skin barrier function; supports lipid production and reduces transepidermal water loss

25 studies | 1,500 participants
Vitamin EB
400 IU daily oral; topical application as needed

Antioxidant protection for skin; supports moisture retention; both oral and topical benefit

15 studies | 800 participants

Supporting Stack (Tier 2)

Vitamin DB
2000-4000 IU daily

Supports skin barrier function and keratinocyte differentiation; deficiency can worsen dry skin

12 studies | 700 participants
Hyaluronic AcidB
120-240mg daily oral

Oral hyaluronic acid may improve skin hydration from within; holds 1000x its weight in water

10 studies | 600 participants
CollagenB
2.5-10g collagen peptides daily

Collagen peptides improve skin hydration and elasticity; support skin matrix

15 studies | 800 participants
ZincB
15-30mg daily

Essential for skin health and wound healing; supports skin barrier integrity

10 studies | 500 participants
Gamma-Linolenic Acid (GLA)B
500-1000mg GLA daily (from evening primrose or borage oil)

Omega-6 fatty acid that supports skin barrier; from evening primrose or borage oil

12 studies | 600 participants
BiotinC
2.5-5mg daily

Supports skin, hair, and nail health; deficiency can cause dry, scaly skin

6 studies | 300 participants
Vitamin AB
5000-10000 IU daily (from diet + supplements; avoid excess)

Essential for skin cell turnover and barrier function; prevents keratinization

10 studies | 500 participants

How It Works

Xerosis (dry skin) occurs when the skin's outer layer (stratum corneum) lacks adequate moisture and lipids. The result is rough, flaky, tight-feeling skin that may crack and itch. It's extremely common, especially in winter, with aging, and in certain medical conditions.

COMMON CAUSES:

•Environmental factors (low humidity, cold weather, wind, sun)
•Excessive bathing with hot water and harsh soaps
•Aging (reduced oil production)
•Medical conditions (eczema, psoriasis, hypothyroidism, diabetes, kidney disease)
•Medications (diuretics, retinoids, cholesterol medications)
•Nutritional deficiencies

TOPICAL CARE IS FOUNDATION:

•Moisturize immediately after bathing (within 3 minutes) while skin is still damp
•Use gentle, fragrance-free cleansers (avoid bar soaps)
•Bathe in lukewarm (not hot) water and limit shower time
•Use thick creams or ointments, not thin lotions (look for ceramides, hyaluronic acid, glycerin, petrolatum)
•Humidify your home in dry seasons (30-50% humidity)
•Avoid irritants (fragrances, dyes, wool)

* Omega-3 Fatty Acids (fish oil) are essential building blocks for the skin's lipid barrier. They reduce transepidermal water loss and improve hydration from within.

* Vitamin E is an antioxidant that protects skin and supports moisture retention.

* Vitamin D supports skin barrier function; deficiency is associated with dry skin conditions.

* Hyaluronic Acid (oral) can improve skin hydration. It's a humectant that holds water.

* Collagen peptides improve skin hydration, elasticity, and density.

* GLA (Gamma-Linolenic Acid) from evening primrose or borage oil supports the skin barrier.

* Zinc and Vitamin A are essential for skin health.

Expected timeline: Topical moisturizers work immediately but need consistent use. Oral supplements take 4-12 weeks to show noticeable skin improvements.
