What actually helps with dry skin

Skin that feels tight, rough, flaky, or itchy due to inadequate moisture retention, often worsened by environmental factors or nutritional gaps.

Omega-3
fatty_acidwith_food
Strong

Omega-3 fatty acids are incorporated into skin cell membranes, improving barrier function and transepidermal water loss. They support ceramide production, reduce inflammatory skin responses, and enhance skin lipid composition for better moisture retention.

Dose: 1000–2000 mg

Vitamin E

Strong

Vitamin E protects skin cell membranes from lipid peroxidation by free radicals. It supports the skin's lipid barrier, reduces UV-induced photodamage, improves moisture retention, and works synergistically with vitamin C for skin protection.

Dose: 200–400 IU

Vitamin A

Strong

Vitamin A (retinol) is essential for skin cell differentiation, turnover, and sebaceous gland function. It promotes keratinocyte maturation, enhances the skin barrier, stimulates collagen production, and normalizes desquamation to prevent dry, flaky skin.

Dose: 2500–5000 IU

Astaxanthin
antioxidant
Strong

Provides UV protection to skin cells, reduces wrinkle depth via collagen protection, increases dermal moisture.

Dose: 4–12 mg

Glutathione
antioxidant
Strong

Modulates melanin synthesis pathways, provides antioxidant protection to skin cells, enhances dermal hydration.

Dose: 250–500 mg

GLA
fatty_acid
Strong

Gamma-linolenic acid restores epidermal barrier function, DGLA conversion provides anti-inflammatory prostaglandins.

Dose: 240–480 mg

Collagen
amino_acid
Strong

Oral collagen peptides accumulate in dermal layer, increasing fibroblast density and collagen/elastin production.

Dose: 2.5–10 g

Iodine
mineral
Moderate

Thyroid hormones regulate keratinocyte turnover and sebaceous gland activity, maintaining skin hydration and barrier function.

Dose: 150–250 mcg
