Is 20 a good age to start incorporating Vitamin C? When and how do you use it in your skincare routine? 
Please suggest me some of the best asian Vitamin C product you've used.

Vitamin C

People who apply toners with your hands, how do you do it? Do you 'pat pat' or do you smoothly glide it all over yout face and neck?
And do you think the way of application matters?
This might sound like a stupid question but I'm genuinely curious lol

How do you apply your toner?

As the topic suggests, how do you all apply products on your back? Do you have a tool for it? I look like I'm trying to break my arms and dislocate my shoulders on purpose when I'm applying lotion on my back. HELP!!
