Feel self conscious about my eyes - ptosis or excess skin? (Photo)

Hello, I'm a 29 year old male and I have had some cosmetic concerns around the appearance of my eyes that I'm not sure can be attributed to ptosis, excess or loose skin or just my general facial anatomy. I feel like I look tired often and whenever I smile, my eyes seem to squint pretty badly and can look very closed in photographs. Please can I have advice on what this may possibly be attributed to so I can book for a further consultation. I have attached photographs. Thank you.
