James definitely becomes one of those influencers™ and it's more apparent when BTR gets big about skincare brands. And he does not do his mother's because no, your skin should not burn if you put ( skincare item ) on you. But before he can even get over his head, Kendall and Logan do what they can to make him come back on the ground. Because they do not need another repeat of tangerine James / "Hollywood Fever" at all.
But they also make sure to let him know that he still looks good just the way he is like you don't need to look a magazine cover when we play hockey, etc. 'Cause James that one person who gets worried about his appearances and that.
BTR coming out with their own skincare line would be such a flex tbh. James probably freaks out about perfect this and perfect that all the time and Kendall and Logan (and carlos) have to pull him back before james almost gives up music for skincare stuff.
Once that happens James just uses his skincare knowledge to make sure his boys are taken care of. Since it's not being used anywhere else. It's not even to make sure the boys look good (though that's a plus) - it's his love language, knowing that his S/O's feel good and that they're clean, that they feel happy about themselves in a way James himself never was. Despite Kendall and Logan promising him Jamed just never thought he was perfect (childhood trauma perhaps). James likes spoiling them with lavish home spa days with bath bombs and shampoos Logan is pretty sure too expensive to be sold at Walmart. They have a big bathtub so they can all wedge inside it and they just let James do what he wants because they trust him. He inevitably trusts Kogan to wash his hair for him one day and he feels so much better than he ever does when he does his own hair.
