Covering Sun Line

[hardy49]

I play quite a bit of sport and, consequently, I have a noticeable difference between where my shirt covers my skin and the rest - especially around the neck and arms
Is there anything you can recommend that I can use to cover the non suntanned areas. I am a bit wary of using anything as I have a sensitive skin but would be very grateful for any help

Why would you want to cover it when your shirt already performs this function ?

I am restricted to the type of tops I can wear
