There’s so many blending modes in Krita it’s hard to say which would be optimal. 
Colour dodge is my first instinct. There are many modes aimed at lighting effects such as Hard Light, Soft Light, Vivid Light.
I mostly use Hard Overlay as a general adjustment and effects mode - it’s capable of this kind of effect, but more complex to use than a singular focused mode like dodge.
You could also just paint it that way on normal - you don’t have to rely on effects! 
edit: There is also this new mode available in the Beta that might be suitable: I create a new blending mode to mock [light on albedo]/[HDR paiting],is anyone interested?
