Mature skin is often thinning, crepey, blotchy and lax. These issues are due to the aging process itself typically complicated by past sun damage and other forms of environmental damage that produce free radicals breaking down the tissue. Tanning and smoking produce the most damaging effects.
The best treatments are based on many considerations including location of the treatment area. For example: face vs neck, chest, arms, abdomen, legs...
In my practice, I often use a combination of treatments. For upper eyelids I use CO2 laser resurfacing. For very thin skin on the face I begin with a collagen building supplement and Ultherapy or a sublative laser treatment. For most other patients I treat with Morpheus8 Radiofrequency skin remodeling which can be applied to skin just about anywhere on the body with the exception of upper eyelids. I treat a lot of arms, thighs and abdomens with this modality.
And as with all energy-based tissue remodeling/resurfacing treatments, living a healthy life-style is a must for the best outcome and preservation of results. Eat a healthy diet, sleep well, drink water-at least 1/2 your ideal body weight in ounces every day. Manage stress and ensure you are getting enough micronutrients.
