This invention relates to certain divalent and polyvalent d-orbital metals
of first transition series of the Periodic Table of Elements, from Group
IV to Group VI, and including Molybdenum, complexed concurrently with an
amino acid, or an equivalent of an amino acid, and a hydroxy acid in a
novel spirocyclic bidentate chemical complex form (FIG. 1). Upon topical
application said metal complexes undergo enhanced skin penetration
without causing skin irritation. The said metal complexes are useful for
topical conditions that include dry skin, xerosis, ichthyosis, dandruff,
brownish spots, keratoses, melasma, lentigines, age spots, dark circles
around eyes, skin pigmentation, topical inflammation, liver spots,
pigmented spots, wrinkles, blemishes, skin lines, oily skin, acne, warts,
eczema, pruritic skin, psoriasis, inflammatory dermatoses, disturbed
keratinization, dandruff, bacterial infection, fungal infection, wound
healing, body odor, and skin changes associated with aging.
