20% Its like a vodka shot tan for a Tanaholic it will make her very brown for a few days but she will have to deal with the hangover !! as with any high dha solution the fade off will not be as good lots of moisturiser to stop her fading badly some people myself included can handle anything. others suffer, just tell her what may happen if shes still keen to try stronger i will do some 25% lol some people are just "Mad for it" others prefer to be a little subtle,
I haven't tried your 20% yet Steve, what if a pale person wanted it? what would I do tell them to pee off lol or just spray them?
