A deep wrinkle has appeared on the left side of my eye.

I gained weight, so my face became chubby and I had no wrinkles, but one day I woke up and saw in the bathroom that a wrinkle had appeared near my left eye. I sleep on my side, so I thought it was because of that, and I applied eye cream diligently, so it got better. But since I keep sleeping on one side, a deep wrinkle has formed only on the left eye area, so even when I smile, it shows. I think I should go to a dermatologist for a consultation. Since it's only on one side, it's more stressful.
