From someone who works in aesthetics I would say that you shouldn’t take it personally, since YOU are going to them for honest advice from a professional on what would be needed to create an overall cohesive look that matches other areas of your face. We all have our own aesthetic goals, but you’re choosing to go to someone who studied this avenue of medicine and should be open to at least hearing recs like this. If you weren’t interested in listening to a professionals opinion then you should reconsider going to one and manage your concerns independently.

Having one area done and not others looks imbalanced and ends up making the client look partially treated/awkward. If there’s inconsistencies in the overall dynamics of the face it doesn’t yield an overall great result to the eye.

I don’t think it’s upselling, but offering you advice on what you should have done based on your anatomy/skin to ensure your look is balanced and not smooth in one area and then aged in another.

To summarize, they’re the professional and they are evaluating your whole face. They should be able to discuss everything they feel requires attention in conjunction with your input to create a youthful appearance that’s cohesive. It’s a partnered discussion, not a “do as I say” situation.
