Hi, Thanks for your question and pictures. Based on the pictures provided, it seems you start to loose collagen (like everybody else :) due to the aging process, sun exposure ?, life style (smoking, excessive loose weight, alcohol, sugar etc.) ? , genetic ?etc. This leads to skin losing its elasticity, reduce thickness (skin became thinner) and increase wrinkles and sagging. Our body begins to lose collagen at around 30 years old however the effects become noticeable after several years. Unfortunately, there's no way to stop this process however there are several cosmetic treatments can reduce and build/improve collagen. Over the years, many new devices have become available for addressing skin laxity including laser therapy (e.g. CO2 , Erbium etc.) , radiofrequency (RF) and micro-needling, ultrasound, intense pulsed light (IPL), collagen-stimulating dermal fillers. In you case, it is important to perform a detailed medical ( including lifestyle etc.) where the doctor/surgeon is able to give you several options. The key here is to understand what you would like to achieve, what are your expectations In our clinic we offer a bespoke assessment and treatment plan with combination of Dermal fillers and Morpheus 8 (3 sessions 4 to 6 weeks apart)/Facetite/Accutite in combination with Profhilo, collagen-stimulating dermal fillers ( e.g. Radiesse, Sculptra etc. ), collagen drink and skincare Obagi/Zo skin health. These combined procedures will allow to increase the probability of skin tightening and so reduce more the risk of "saggy" skin. There is also the possibility to consider Laser resurfacing with CO2 or Erbium if indicated. Aftercare recommendations including healthy diet and exercise can also help. I would recommend to make an appointment with an expert aesthetic doctor for a medical assessment in order to make a bespoke treatment plan. Best Wishes, Dr Fiore
