What supplements have evidence for improving dry skin?

Oral hyaluronic acid, ceramides, collagen peptides, and omega-3 fatty acids have clinical evidence for improving skin hydration. Ceramides directly support the skin barrier lipid matrix. Collagen peptides increase dermal moisture content. Evening primrose oil and borage oil (GLA) may also support skin hydration from within.

Can supplements alone treat chronic dry skin?

While oral supplements may improve skin hydration from within, topical moisturization remains the cornerstone of dry skin management. A consistent skincare routine including gentle cleansers, ceramide-based moisturizers, and humectants (hyaluronic acid, glycerin) is essential. Supplements may provide additional support but do not replace topical care.

When should someone with dry skin see a dermatologist?

See a dermatologist if dry skin is severe, cracking, or bleeding; does not improve with regular moisturization; is accompanied by intense itching, redness, or scaling; or develops suddenly. Chronic dry skin may indicate underlying conditions such as eczema, psoriasis, hypothyroidism, or ichthyosis that require medical treatment.
