You already look youthful, but Botox and laser skin resurfacing can give a nice glow to the skin and prevent the crow's feet and sun damage from becoming more apparent as we age. From your photographs, it doesn't appear that you need any fillers. All the best!
From your photo, you look great! It's hard to tell exactly what's going on, but. . . . crows feet can be treated with Botox/Dysport, and hollowing under the eye can be treated with various fillers (we call this area the lid-cheek junction, where the eyelid skin meets the thicker cheek skin). Don't forget topical skin care - Elastiderm does very nice things to smooth the skin of the eye area, and you should always use a good sunblock. Laser resurfacing is a possibility, and there are lasers of various strengths and invasive qualities. It looks like you might have a bit of thick lower lid muscle (are you a tiny bit bunchy under your lower lashes?) - that would have to be addressed with a limited surgery. So there are lots of options - a consult with a board certified plastic surgeon or dermatologist will help you make good treatment choices.
You are young but sometimes these problems occur early and are bothersome to our younger patients for a variety of reasons. It's actually good to start treating them early--you may ward off or delay the need for a surgical intervention! I typically tackle problems like this using a combination approach--thin filler products to smooth the lid (e.g. Restylane, Belotero), a neurotoxin (e.g. Botox) to prevent the bunching & wrinkling of skin that occurs around the eyes w/ muscle movement/squinting), and I sometimes will add a laser resurfacing to help tighten and smooth the wrinkles that have already developed. Make sure you consult with a board certified plastic surgeon or dermatologist who has experience treating this problem area--not all providers feel comfortable working around the eyes!
There are numerous options to assist you, mostly fillers for the under eye wrinkles and botox for the crow's feet. The two can be used alone or in combination for best results. Most dermatologists and plastic surgeons are skilled at providing these services.
