One of the things that stress provokes on me is skin allergy. I have tried a lot of different brands of face creams, expensives, hypoallergenics, etc. I couldn't find a cream to moisture my face and using make up was worse because it made my skin get more dehydrated and it looks cakey. The only that really worked for my skin is Korean brands. They are excellent, cheap and they use the best natural ingredients.
Few months ago I went to eBay and I bought some creams from Korea to try
For the night rutine I'm using
Collagen Power Firming Eye Cream by Mizon for my eyes zone
All in one Snail Repair Cream by Mizon which cured my allergy
I use eos lips balm but that is not from korea
For the day I use
Hyaluronic acid 100 by Mizon which helps the skin to retain water
After that I use the snail cream for humect the skin and a FPS 50 if this is summer
Every 2 weeks I'm using
Tomatox by TonyMoly, a cream for face massages which containg tomato extrated. It vitalizes and clarify the skin.
Black Out Pore by Secret Key, this is a cream of activated charcoal for cleaning and minimizing pores. This is not the peel off cream, that one hurts. This one you wash with warm water when it get dry.
Therapy Air masks by Etude House, it's a face mask that you can get in more than 15 varieties and all of them are awesome. They cost 1usd or less and trust me, they are amazing!
I also use Gold Premium First eye patch to keeps skin moist and clear, this has colloidal gold components. Another thing I use so much is aloe vera. I take it directly from the plant.
I do a peeling on my face using mandelic acid, this minimize pores and renews the skin.
After try all those creams I can say I won't ever buy again a cream from Vichy, Loreal, Estee Lauder , etc.
