I have been using retinol night cream regularly but have noticed fine lines and wrinkles around my mouth. Can anyone suggest the best anti-ageing treatment?

Retinol is an effective preventive therapy against fine lines on the face, though it can not prevent all signs of aging. There are multiple anti aging treatment options available depending on your concern.. Fine lines and wrinkles, if mild, can be treated by chemical peels and laser toning, which rejuvenate the upper damaged layers of skin and clear pigmentation. They require multiple sessions with regular maintenance. Sagging and loose skin is best treated by energy based devices like HIFU (High intensity focussed ultrasound), radiofrequency tightening etc. These induce collagen production at deeper layers of skin and can destroy fat cells. 1-2 sessions can give long lasting effects. For muscle contraction induced lines, botulinum toxin injections are quite effective. There are hyaluronic acid based injectables that can target several concerns like hydration of dry skin, collagen induction for skin tightening as well as give support to deeper structures changing the face contour and giving non surgical face lifts. Surgical options are available for severe cases not responding to any of the above treatments. Consult with your dermatologist to know details of the different treatment options and which ones would be suitable for you.
