Hormonal changes and seasonal factors affect skin hydration needs

Research indicates that skin characteristics often change significantly during perimenopause and menopause. A 2025 review in the Journal of Cosmetic Dermatology suggests that declining estrogen levels are linked to reductions in collagen production, elasticity, thickness, and skin hydration.

Studies indexed in PubMed have also identified lower skin hydration levels in post-menopausal women compared to those in the ovulatory phase. Dermatologists note that products which were effective for years may suddenly seem inadequate because the skin's physiological needs evolve alongside hormonal shifts.

Seasonal changes also necessitate adjustments in skincare. During summer, experts recommend prioritizing lightweight textures such as fluid lotions and gel-creams to avoid oiliness while maintaining hydration. Specific ingredients like hyaluronic acid, glycerin, and ceramides are recommended based on whether the skin is normal, dry, or oily.
