Crow's feet — Lateral canthal lines

Why do crow’s feet wrinkle earlier than other areas?

The skin around the eyes is one-third the thickness of cheek skin, has fewer oil glands, and sits directly over the orbicularis oculi muscle, which moves tens of thousands of times a day (blinking, squinting, smiling). With every muscle contraction, the skin folds along the same lines; as collagen depletes with age and sun exposure, the skin loses its snapback capacity, gradually turning these fold lines into permanent, etched-in wrinkles.

Dynamic vs. static wrinkles — how to tell them apart

Look in the mirror with a relaxed face: if the outer corners of your eyes are smooth and lines only appear when you smile, you have dynamic wrinkles. If the lines remain visible at rest, they are static wrinkles—meaning the skin has lost its structural integrity along the fold lines. Static wrinkles almost always coexist with a dynamic component, so treatment typically requires a combination approach. Fine, cross-hatched under-eye wrinkles (crepey skin) indicate thin, dry, and inelastic skin, which differs from tear troughs (volume deficiency) and under-eye fat pads.

Why doesn't Botox erase static wrinkles?

Botulinum toxin relaxes the orbicularis oculi muscle so the skin no longer folds, eliminating dynamic wrinkles and gradually softening shallow static lines over time as repetitive creasing stops. However, deeply etched wrinkles require local structural restoration: intense hydration and collagen stimulation via skin boosters, microneedling RF, or laser therapy. Topical creams can hydrate and smooth the skin's surface, but they cannot replace these clinical mechanisms.

What determines the degree of improvement?

The stage of the wrinkles, skin thickness and hydration levels, habitual squinting (uncorrected myopia, sun exposure), smoking, and treatment consistency. Botulinum toxin results last 3–4 months; skin boosters require an initial series followed by maintenance sessions; laser and RF therapies require a structured protocol based on the wrinkle severity.

How does BonBoz approach crow's feet?

An aesthetic dermatologist directly examines and evaluates the skin under magnification, stages dynamic vs. static wrinkles, and assesses skin thickness alongside any coexisting tear troughs or under-eye bags to ensure targeted treatment. Tailored protocols by stage: low-dose botulinum toxin for dynamic lines (preserving natural facial expressions when smiling); combined with skin boosters, microneedling RF, or laser therapy for static lines; or referral to a plastic surgeon if significant skin laxity requires surgical excision. Doctors perform all injections and procedures directly; longevity and potential risks are clearly explained in advance.
