Under-eye lines are very common and usually develop from a combination of factors: thin skin, repetitive movement, early volume changes, sun exposure, and gradual collagen loss. Because there isn’t a single cause, the most effective way to address them is almost always a multi-modality approach rather than relying on just one treatment. From a prevention and treatment standpoint, I typically think in layers: Skin quality first: Medical-grade skincare with ingredients like retinoids (used cautiously around the eyes), antioxidants, and daily SPF can help strengthen the delicate under-eye skin and slow progression over time. Neuromodulators (Botox/Dysport): When lines are primarily from movement, very conservative dosing can soften expression without compromising natural facial dynamics. Collagen-stimulating treatments: Options such as microneedling, RF microneedling, or laser-based therapies can improve fine lines by encouraging your skin to produce more collagen, this is especially helpful for crepey texture. Volume support (when appropriate): In select patients, subtle support with filler or biostimulatory products may help if under-eye hollowing is contributing to the appearance of lines. This must be approached cautiously and conservatively. Lifestyle considerations: Hydration, sleep quality, and sun protection play a bigger role here than many people realize. The key is personalization. Under-eye anatomy is complex, and what works beautifully for one patient may not be appropriate for another. A thoughtful, ethical provider will assess skin quality, movement, volume, and your long-term goals before recommending a tailored, multi-modality approach designed to keep results natural and balanced. Aesthetic treatments should always be discussed with and performed by a trained, licensed, and medically certified aesthetic provider.
