For me, it doesn't mean that expensive products are necessarily the best. I've been using the No.7 range of products by Boots for a year now and loving it. It is available from most Boots shops (for example the ones in Bangkok) or from supermarkets like Target in the U.S.
Here are some of the products that I've been using -
Eye cream - use it for my travels. It's non greasy and light on the skin and fragrance free.
4-in-1 facial wet wipes - Great for cleaning off makeup without leaving the skin dry, it's scentless and supposedly moisturizers and tones the skin at the same time (hey, it's good to have everything in one package right?). My only gripe is that I wish it had come in smaller packages like 10 pieces in a pack.
High lights illuminating lotion - my latest acquisition on my last trip, I don't wear foundation or pressed powder and I've heard that this gives a natural glow so I'm giving it a try out.
Other products to consider - my friend swears by the beauty serum and I heard the night moisturizing cream is good too.
