Under-eye creases are very common, and the right treatment depends on whether they're caused by skin quality, volume loss, muscle movement, or a combination of these factors. From your photo, it appears that the creases are most noticeable in the thin skin beneath the eyes, which often becomes more prominent with age as collagen and elasticity decrease. There are several options that may help: Skin quality treatments: If the creases are primarily due to thin, crepey skin, treatments such as fractional laser resurfacing, RF microneedling (performed conservatively around the eye), or platelet-rich fibrin (PRF) may help stimulate collagen and improve texture over time. Hyaluronic acid filler: If there is accompanying volume loss or a tear trough hollow that is making the creases more noticeable, a small amount of filler can soften the transition. This should be done carefully, as the under-eye area is delicate and not everyone is a good candidate. Neuromodulators (Botox): If the lines become much deeper when you smile or squint, tiny amounts of Botox in selected areas may help reduce dynamic wrinkling. It won't correct skin laxity or deeper static creases. Medical-grade skincare: Daily sunscreen, a gentle retinoid (if tolerated), and products containing peptides or hyaluronic acid can help improve skin quality over time, although results are gradual. I would avoid assuming filler is the answer for every under-eye concern. In some patients, adding volume can actually make the area appear puffier if the main issue is skin laxity rather than hollowness. The under-eye area often benefits most from a combination approach rather than a single treatment. Improving skin quality while addressing any underlying volume loss, if present, typically produces the most natural-looking and long-lasting results.
