Every morning, after having my oat, I will take one 1000mg Vitamin C. I bought the Vitamin C in US when I was there few weeks back. I bought 2 bottle, one for my mum and one for my self. Each bottle consists of 500 tablets. It is cheap in US if compare to Malaysia. Besides the tablet form, vitamin c serum is another alternative that you may opt to. It is good to have Vitamin C everyday to keep you healthy and beautify your skin.
