Here is some information about calcium that was written by Vispi Kanga in Dec 2007:
"Calcium is just as critical to the health of skin as zinc. In the late 1990s the National Cancer Research Institute (NCRI) published the results of extensive research regarding calcium. Calcium regulates cell turnover via cell "differentiation" stimulated by protein kinase C (PKC enzyme). Increased epidermal calcium stimulates rapid cell turnover and, therefore, turnover can be up-regulated with absorbable topical calcium resulting in plumper looking skin. Calcium regulates the lipid barrier process. High calcium content in the upper epidermis helps maintain continual and efficient barrier functions. Patients with dry skin or dry skin due to weather respond well to topical calcium treatment. Cold winter weather, microdermabrasion and peeling strips the skin's moisture barrier. Calcium can significantly reduce dryness caused by microdermabrasion making the skin look well hydrated and fuller in appearance.
The NCRI observed that people with low skin calcium content experience greater premature aging of the skin and greater incidence of skin cancer. Conversely, people with high skin calcium content experience less premature skin aging and less incidence of skin cancer. Based upon this and other research, scientists believe calcium is also the regulator of the skin's production of powerful antioxidants. Calcium is known to have a direct relationship with catalase, a powerful antioxidant produced by skin. Calcium, besides being necessary for many body functions, helps with collagen formation and protein structuring in DNA and RNA. The latest research shows that a lack of Calcium results in skin appearing fragile and thin- even papery, as supporting layers weaken and loose density. After age 55, the body experiences a significant loss of Calcium as it is less able to absorb and retain this essential nutrient. Calcium is associated with several enzyme activities, as a mediator of some hormonal responses, signal transduction, blood coagulation and muscle contraction. Intracellular calcium appears to form a calcium-protein complex that has an important role in regulating cell membrane permeability and inducing lamellar body secretion."
