A bit late on this thread but I don't think Molly mentions ANY brand without a deal in the middle of it. I don't think she paid for any of those Ryanair flights.
We are talking about an influencer that allegedly uses the brands that she is CASUALLY promoting that week. Today is L'Oréal tomorrow may be a different random one, who cares.
Her body situation is something I've noticed as I grew older, gals with great metabolism - even if you don't have kids, when you hit 25 there's a wall and if you don't take care of your diet, don't exercise and live stressed all the time (travelling 10+ flights a year with a baby and a "fiancé" is stress) - yeah no surgery is going to save her looks.
Kim Kardashian, you can tell she has a very healthy routine besides the BBL or whatever.
