Cold Cream Orlane's new Hydro-Climat, or "emergency cream," is intended for complexions under the influence of wind, sun, snow and ski trails. It ideally should be applied before exposure, says Ana Lopo, an Orlane representative, and it will keep working for eight hours. That should see you through the longest slope. At the Broadway in March, $20. Warming Trend As if to ensure that there is life after the thaw, Germaine Monteil's spring makeup colors have just been announced. Beaute en Fleurs is all shades of azalea, iris, tulip and geranium. The colors are clear and bright, designed with an eye toward more romantic clothes of cotton lace, chintz and organza. At May Co. in February, $6-$14. Weatherproofers Giorgio's new low-alcohol after-shave balm with collagen was created to help keep men's skin supple in any weather--and it doesn't sting. At Giorgio, $20. And for women who like to languish in a moisturizing bath, Perlier's Honey Cream Bath, made with pure honey and beeswax, soothes dry skin. At Bullock's, $16. Soft Soap For years, skin-care experts insisted that soap was the worst thing you could use to cleanse your face. Lately, they've revised their thinking. Detergents are the real problem, they say. Skin-care specialist Ole Henriksen says that the best-selling product in his line of complexion aids has long been his detergent-free soap with a primrose-oil base. Crystal-clear, it's pressed into a jar rather than into a bar. Henriksen applies it to all skin types--and on such clients as Nastassja Kinski and Maud Adams--with a wafer-thin sponge, which helps slough off dead cells.
