1. A method for diminishing dermatological signs of aging in human skin comprising, in any order, the steps of (1) topically applying to an area of the skin in need thereof, at least once daily, a first skin treatment composition comprising, in a physiologically compatible vehicle, an effective amount of a retinoid for a first period of time comprising from 6 to 15 days; (2) topically applying to said skin, at least once daily, a second skin treatment composition that is different from said first skin treatment composition for a second period of time comprising from 6 to 15 days, said second skin treatment composition comprising, in a physiologically compatible vehicle, an effective amount of phytol; and (3) repeating steps (1) and (2) for a number of times sufficient to diminish said dermatological signs of skin aging. 2. The method according to claim 1, wherein said diminishing dermatological signs of aging is selected from the group consisting of: (a) treatment, reduction, and/or prevention of fine lines and/or wrinkles;(b) reduction of skin pore size;(c) improvement in skin thickness, plumpness, and/or tautness;(d) improvement in skin smoothness, suppleness and/or softness;(e) improvement in skin tone, radiance, and/or clarity;(f) improvement in procollagen, and/or collagen production;(g) improvement in maintenance and remodeling of elastin;(h) improvement in skin texture and/or promotion of retexturization;(i) improvement in skin barrier repair and/or function;(j) improvement in appearance of skin contours;(k) restoration of skin luster and/or brightness;(l) replenishment of essential nutrients and or constituents in the skin;(m) improvement of skin appearance decreased by aging and/or menopause;(n) improvement in skin moisturization;(o) increase in skin elasticity and/or resiliency;(p) treatment, reduction, and/or prevention of skin sagging;(q) improvement in skin firmness;(r) reduction of pigment spots and/or mottled skin; and(s) improvement of optical properties of skin by light diffraction or reflection. 3. The method according to claim 1, wherein said diminishing dermatological signs of aging comprises a reduction of fine lines and/or wrinkles. 4. The method according to claim 1, wherein said diminishing dermatological signs of aging comprises a reduction of pigment spots and/or mottled skin. 5. The method according to claim 1, wherein said first period of time is 7 days, and said second period of time is 7 days. 6. The method according to claim 1, wherein said first and second periods of time are consecutive such that one begins on the day following the last day of the other. 7. The method according to claim 1, wherein said second skin treatment composition does not comprise an effective amount of a retinoid. 8. The method according to claim 7, wherein said second skin treatment composition comprises one or more α-hydroxy acids. 9. The method according to claim 8, wherein said α-hydroxy acids include one or more of glycolic acid, lactic acid and citric acid. 10. The method according to claim 7, wherein said second skin treatment composition comprises one or more antioxidants. 11. The method according to claim 10, wherein said antioxidants include one or more of ascorbic acid, beta-carotene, hexylresorcinol, tocopherol and its derivatives, phytanic acid, and thiodipropionic acid and its esters. 12. The method according to claim 1, wherein said physiologically compatible vehicles are independently in the form of oil-in-water emulsions, water-in-oil emulsions, aqueous serums, and/or gels. 13. The method according to claim 11, wherein said physiologically compatible vehicles are each in the form of oil-in-water emulsions comprising from 0.01%40% by weight of emulsifier. 14. The method according to claim 1, wherein said first skin treatment composition comprises from about 0.01% to about 1% by weight retinol, and said second skin treatment composition comprises from about 0.01% to about 10% by weight phytol, from about 0.01% to about 10% by weight glycolic acid, and from about 0.01% to about 10% by weight thiodipropionic acid or esters thereof. 15. A method for treating fine lines and/or wrinkles in the skin comprising, in any order, the steps of (1) topically applying to an area of the skin in need thereof at least once daily a first topical composition comprising, in a physiologically compatible vehicle, an effective amount of a retinoid for a first period of time comprising from 6 to 15 days; (2) topically applying to the same area of skin at least once daily a second topical composition that is different than said first topical composition for a second period of time comprising from 6 to 15 days, said second skin treatment composition comprising, in a physiologically compatible vehicle, an effective amount of phytol; and (3) repeating steps (1) and (2) for a number of times sufficient to reduce the severity or number of fine lines and/or wrinkles. 16. The method according to claim 15, wherein steps (1) and (2) are repeated at least four times.
