It turns out that the Bedford, N.Y., bathroom cabinet of Martha Stewart, 72, is as well stocked as its gardening shed. The many products help prime Ms. Stewart for on-air appearances like her show, “Martha Stewart’s Cooking School,” which began airing its third season on PBS last week.

SKIN CARE

I get up a couple hours before I’m supposed to leave in the morning and I’ll put on a mask. I like the Yon-Ka Gommage 305 or the Susan Ciminelli Hydrating Gel Mask right now. Or I’ll use the collagen mask from Mario Badescu or the Chanel Correction Lift, a firming mask, which works great for me. I’ll do this about five days a week and I don’t repeat the same mask two days in a row. I’ve always done this — well, basically since I discovered masks. I have to wear makeup for photo shoots, television and appearances, so I have to make sure my face is extremely clean in the morning. Then I shower and I wash it all off.

I slather myself with serums. First, it’s a toning lotion. Right now it’s either the Yon-Ka Lotion or a more specific spray, like the rose spray from Mario Badescu. I spray my whole face and body and then its Susan Ciminelli Marine Lotion from head to toe. I use the same products on my body as I use on my face. I don’t think there’s really any difference between the two, so the more moisturizers and serums you use, the better off you are. Then I might use a vitamin B or SkinCeuticals C E Ferulic serum. I’ll also put on Clé de Peau or SkinCeuticals moisturizer. With all of these serums, I find I don’t have to put on an eye cream, although my facialist insists I put one on. Sometimes, I will and the Clé de Peau is good or Caudalie has one — it’s the fancy one from their high-end line — and it’s very good, too. At the end, before any makeup, I use SkinCeuticals Physical Fusion UV Defense. If I’m not going to use foundation, I’ll use the tinted version, or if I use foundation, it’ll be the white one. Otherwise, I do my best to stay out of the sun. That’s very important. I do a lot of outdoor activity like gardening and I try to cover up and do SPF. Actually, I just bought a new sun hat that goes over your riding helmet. It’s pretty ugly, but it works.

If I’m traveling that day, I’ll be sure to have my Yon-Ka Lotion with me, which is a spray. On a recent plane ride to L.A., I sprayed myself five times. It’s hydrating, so I don’t look like a prune after flying.
