I'm 28 f and my lip corners are dark and have skin folds at lip corner which create a line downwards. Treatment? (photo)

Thank you for your question and for sharing your photograph.  Based on your photo, you appear to be a great candidate for a hyaluronic acid based dermal filler such as Juvederm to treat your downturned mouth.  Beautiful and natural results can be achieved.  Please be sure to see an expert injector for an in-person consultation to fully discuss your concerns and your goals and expectations in order to determine the best treatment plan.  Hope this helps and best wishes! 

Thank you for your question. Yes, you can have the corners of your mouth injected with a hyaluronic acid dermal filler. This will help improve the downward appearance/skin folds that you have noticed. I recommend having a consultation with an expert to help determine the best treatment plan for you. Best of Luck!

It looks like you have very settle marionette lines which can be easily corrected with fillers around the lip area (lateral mouth commissures). This would be a very quick and simple procedure - based on your photographs 1 syringe of either Restylane (Refine) or Juvederm (Volbella or Volift) would be sufficient. Alternatively, your doctor could also consider small doses of botox or dysport neuromodulator to lift the corners of the mouth. Best of luck! 

From your picture, it is hard to see if you actually have true hyperpigmentation (darkening of the skin) at the corners of your mouth or the appearance of darker skin due to shadowing created by the surrounding skin. The corners of your mouth can be injected with a hyaluronic acid filler to improve the downward appearance/skin folds that you have noticed. I would recommend seeing a board certified dermatologist for further evaluation and treatment. If the skin around your mouth is truly darker, a dermatologist will be able to help you with that issue as well as inject any filler that is needed. Thanks for your question!

Some people just look like this and it's normal. The trouble is when you try too hard and make something that only you see onto a problem that everyone sees. I'd just stick with HA fillers for now, You'll get better, but not perfect.
