Aging of the skin is a multifactorial phenomenon in which ongoing intrinsic changes combine the cumulative effects of chronic exposure to the elements, primarily UV radiation, in a synergistic fashion, causing the skin to lose its thickness and elasticity and develop wrinkles. There is now an increased interest in a wide range of non-ablative treatments for skin aging, which are used to rejuvenate skin with minimal downtime and complications. As the demand for minimally invasive rejuvenation is increasing, different modalities have been designed to produce favorable alterations in the dermis with no epidermal damage via photomodulation, selective photothermolysis, fractional photothermolysis, radio waves, electro-optical synergy, injectable fillers, neurotoxins, skin needling and biorejuvenation to stimulate collagen synthesis and rejuvenate the aged skin while preserving the integrity of the epidermis.
