There are two common points to inject the depressor anguli oris (DAO) — but choosing the right one can make the difference between a balanced smile and an asymmetrical result. ⚠️ The issue? The depressor labii inferioris (DLI) overlaps with the DAO, especially at the lower, more medial point. Injecting here puts you at higher risk of affecting the DLI or even platysma fibers, leading to an uneven or dropped smile. ✅ Instead, I prefer to treat the lateral border of the DAO — it keeps me well clea

The depressor supercilii is a small but important muscle that often gets overlooked. 🔎 Key insights for injectors: It crosses the corrugator and is sometimes seen as a branch of orbicularis oculi. Function: contributes to frowning and medial brow depression. Clinical approach: usually treated alongside the glabella complex since it’s tightly meshed with the corrugator. Bonus effect: targeting it can give a subtle lift to the medial brow. 💡 Injector tip: Even though it’s small, ignoring the dep
