Abstract
Boron compounds/complexes, other than boric acid and boric acid salts, are utilized for rejuvenating of skin. The compounds/complexes have a central tetrahedral boron atom covalently bound to four ligands, which may be either identical or different from each other. Preferred ligands include an oxygen, nitrogen, carbon or sulfur atom, and more preferred ligands are saccharides or amino acids that form stable five- or six-membered rings with the boron atom. Especially preferred compounds have a dissociation constant of at least 3,000, and include a saccharide. Especially preferred complexes include a sodium, potassium, magnesium or calcium cation. The compounds/complexes are useful in rejuvenating skin, including decreasing skin wrinkles, improving skin thickness, increasing skin hydration, softness and elasticity, improving the skin color, and decreasing the number and size of age spots. The compounds/complexes are preferably provided in a suitable solvent system, a microemuslion or macroemulsion form, or a suitable liposome, and may be applied in any suitable form, including creams, bath salts, cosmetics, and shampoos.
