Your skin is perfection!
Other than eBay, I have not found any place to purchase Korean brands. Thankfully, Sephora is starting to carry a few Tony Moly items. Hopefully they will expand more into Korean beauty products soon!
Thank you, but honestly my skin isn't very good naturally. I actually have noticeable pores, freckles, acne prone sensitive and uneven skin tone. The products I use have improved it a lot and what it hasn't helped, the cosmetics hide.

Memebox, Jolse, Koreadepart, cosmetic-love and beautynetkorea all sell Korean cosmetics online. You can find a lot on Amazon as well, but usually at a mark up. Sulwhasoo, Etudehouse, Innisfree and Missha all have English language sites & ship to the USA. Although the Sulwhasoo english site seems to have a very limited selection.
I've shopped online at Cosmetic-love, Missha, Memebox, Jolse & Koreadepart with great results, no issues. All but Memebox also include free samples with purchase.
But I think Jolse had the best sample selection though and orders over $100 gets a free full size product, new members get a $3 credit to apply to their first purchase, every purchase earns credit towards future purchases, it offers free shipping and some of the products are a bit less than suggested retail. So for a first order I think I'd recommend them as it gives the most bang for the buck.
