Guardian staffs are usually friendly. Variety choice of products from the shelves. But too bad, they don't provide membership cards like other pharmacies do. My favourite branch is at Satapak Central. They have a huge guardian store just for makeup and skincare, and another store for other products. So basically they have 2 stores in one mall.
Guardian MIDVALLEY is located in Midvalley City, Kuala Lumpur. They can be reached at this number: 03-2284 3844
