I use Korean beauty products (skincare / cosmetic) as my daily routine. I am a HongKonger and could help you to buy korean products in Hong Kong or through korea's online shopping website which cannot order in local UK and store them in a safe place. Once you get an order online etc., I could send out the parcel through post office or other, e.g. SF, DHL, UPs etc.
Look forward to discussing with you in detail.
