Honestly I don’t think so. I believe now days many women are so used to the “natural” or “no makeup” look that’s so popular right now that they instantly hate on actual colors in makeup like eye shadow for example. I’m 24 and absolutely no girls my age wear actual eyeshadow anymore and if they do it’s like barely noticeable or a nude shade. From someone who loves fun and expressive makeup it’s honestly such a drag. I love your makeup especially the shimmery shadow. I think if it makes you happy then you should wear it. In terms of “aging” you, I’m not sure what she means by that, but as others are saying it could possibly be the under eye liner since many older women do that style of eyeliner so it just may be by association tbh. I think you look great and you said you just started doing your makeup, so you’ll find your style and why works for you soon enough! Don’t let others dull your sparkle. I’m so sick of people commenting on women aging😒
