Calcium and Vitamin D Supplementation With and Without Collagen on Bone Density and Skin Elasticity in Menopausal Women—A Randomized Controlled Study

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This review discusses the effects of oestrogen on skin ageing and highlights the need for large-scale clinical trials to evaluate postmenopausal oestrogen use, reporting no new findings.

This review discusses the relationship between estrogen deficiency and skin aging in postmenopausal women, noting potential benefits of estrogen use on skin collagen and elasticity, but reports no new clinical results.

This review reports that collagen as a nutraceutical shows promising results for improving skin health in estrogen-deficient women, but more research is needed for scalp hair, nail health, and optimal dosing of curcumin and glutathione.

This research review observed that topical hormone replacement therapy, particularly estradiol and estradiol-testosterone combinations, significantly increased Type I and III collagen synthesis in the skin of postmenopausal women, suggesting benefits against collagen loss-related skin aging effects such as reduced elasticity and increased dryness.
