Greece has a tremendous selection of locally-made inexpensive, high quality toiletries and beauty products made with indigenous ingredients. If you're traveling with carry-on luggage only, you may want to stock up on these once you arrive in Greece, then pack them and check your luggage on your return trip back from Greece. Most are available at Greek pharmacies and small tourist-oriented markets.
In general, try or smell before you buy when you can. The pretty tourist-packaged items are expensive and often not as good - don't get stuck with something you won't use.
1. Apivita Skin Products
Apivita first came to my attention because they offered a free Minoan-themed screensaver. On my next trip to Greece, I bought their basic skin regime at the Athens Airport pharmacy for the princely sum of 19 Euro for two jars of cream, one for general use and one for the eye area. These both absorb quickly and I had very good results with them, equivalent to much more expensive products. But their stimulating, cooling mask for feet and legs zapped my overly-sensitive skin.
2. HerbOlive Body Butter with Olive Oil
This decadent body butter is made with organic olive oil and is irresistible. A yoga teacher turned me on to this brand. I bought a huge jar of it for less than 6 Euro and bought a second one to bring home intact. I've also used their foot cream and hand lotion, all with excellent results. Lots of brands sound similar - this one is "HerbOlive" as one word with a leaf design. No website; usually found in small markets.3. Carroten Sun Products
Carroten used to be my secret weapon against high sunscreen costs - then they got tired of being the 6 Euro alternative next to the 14 and 18 Euro competition. Now their prices are about the same, but their product is excellent. No, they won't make you orange like a carrot, but keep an eye out for their orange packaging. It usually is still priced slightly less than imported brands. Their lip balm is said to be one of the few to stand up to the Greek sea and sun.4. Mastica Toothpaste
This toothpaste is flavored with a resin from the island of Chios that has been proved to be very beneficial for your mouth health. The flavor is unusual but easy to get used to using. It's available at the Athens Airport in the Mastica Shop as well as local pharmacies and some markets. You'll also find mastica-based candies, lotions, soaps, and other products.5. Clean Skin Olive Hair Mask
This is another high-quality plain-wrap brand with low prices and good products, with many olive-based items. The hair mask - for some reason, almost everything is a "mask" in Greek beauty supplies - seals and conditions the hair and gives it more volume.6. Korres Lotions
I adore the scent of Korres lotions which are wonderfully enticing. However, for my very sensitive skin, I found the concentration of essential oils to be too strong. Very regretfully, I left my lotions behind since they were irritating to my skin. You probably will not have this problem, and I envy you! Their cedar and amber scents are terrific.7. Korres Shampoos
The pharmacy near Door 4 in the arrivals area at the Athens International Airport has a great selection of beauty and health products, with knowledgeable clerks who will help you. I love the Korres line of shampoos which are so effective and rich, you won't need to follow up with a conditioner. A bottle costs about 6 Euro. My favorite? The "Sage and Nettle Shampoo for Oily Hair". It's excellent and I'm hoarding my last bottle until I get back.8. Macrovita Waterlily and Pearl Lotion
This one is expensive - about 16 Euro a bottle - which actually makes me sorry it is so excellent. I was using it without thinking about it and suddenly realized the skin on my legs had vastly improved over just a couple of days' use. It's available widely in Greece and is also carried in small markets.9. Greek Olive Oil Soaps
This is a great souvenir item, so buy plenty. Some are packaged with magnets or metal medallions. Most brands are similar, so smell them, see what the best price is, and enjoy yourself. Don't pay more than 2 Euro a bar; you can find it for much less a little off the beaten path, or in markets.10. Olympian Olive Leaf Extract
Here is a reasonably-priced olive leaf extract from Olympian. Fans claim all sorts of benefits for the substance, which often demands much higher prices.
