At 31, you're actually in a great position to address dynamic under-eye wrinkles because your skin still has a good amount of collagen, and there are several effective options depending on what's causing the lines. From your description, these appear to be dynamic wrinkles, meaning they become visible when you smile or squint and are caused by repeated muscle movement over time. If the wrinkles are minimal or disappear when your face is at rest, they're often very treatable. One of the most effective treatments for true dynamic under-eye wrinkles is a very conservative amount of botulinum toxin (Botox, Dysport, Xeomin, etc.) placed in the lower portion of the orbicularis oculi muscle. The goal is to soften the muscle activity while preserving a natural smile. The under-eye area is delicate, so it's important not to over-treat, as too much can affect facial expression or even make the lower eyelid feel weaker. If the skin has started to develop fine crepey lines that remain visible even when you're not smiling, combining neuromodulators with treatments that improve skin quality often produces the best results. These may include: Fractional laser resurfacing Microneedling (with or without radiofrequency) Platelet-rich plasma (PRP) Skin boosters or hyaluronic acid microinjections in appropriate candidates Prescription-strength topical retinoids to stimulate collagen production over time Looking at your photos, your wrinkles appear to be relatively mild and primarily movement-related, which is reassuring. I don't see significant skin laxity or volume loss that would make under-eye filler the first choice. In fact, filler is generally not my first recommendation for treating fine dynamic wrinkles alone, as it addresses volume loss rather than muscle movement and can sometimes create puffiness if used inappropriately. Since you've spent years working outdoors, don't underestimate the role that UV exposure has played in accelerating collagen breakdown. Daily broad-spectrum sunscreen, UV-protective sunglasses, and a consistent skincare routine with antioxidants and a retinoid can help prevent these lines from becoming more pronounced over time. The good news is that at your age, subtle treatments combined with good skin care often provide very natural-looking improvement. Rather than trying to erase every line, the goal is to soften the wrinkles while maintaining the warmth and expressiveness of your smile.
