Here's the thing. Lily used to get makeup sponsorships back when there were only about 10 influencers to choose from in the UK market (Whatihearttoday, Viviannadoesmakeup, Zoella, Pixi2woo, Fleurdeforce...that era). These girls could get away with doing a little bit of everything with no special skills or creativity (makeup, hair, clothes, etc.) and all types of brands would throw sponsorships at them, because there weren't any of these more professionalized, specialized influencers available yet that they could work with instead. Nowadays, the market is different. The amount of influencers has been multiplied by 100s, there are plenty of influencers who specialize solely in makeup and have built an audience who genuinely cares about makeup and will spend a lot of money on makeup. Of course makeup brands are going to focus on these types on influencers and give them the makeup sponsorships. Why would they pick Lily who has no expertise in makeup, doesn't ever post makeup videos anymore, and whose followers clearly don't watch her for makeup tips? When a makeup brand decides to work with an influencer, they're going to pick the influencer whose audience is most likely to buy their makeup. When you look at Lily's platforms, as a makeup brand, you're not going to see much ROI.
It's nothing to do with being a mother, nothing to do with her eczema, nothing to do with working part time. It's just the fact that her content has zero direction, she exhibits no passion for anything, and her engagement is declining at a steady speed. Her problem is that instead of reevaluating herself, she consistently makes excuses for herself and that's not going to lead her anywhere, except downhill.
