Chronological aging is mainly dictated by inheritance and inevitably occurs over time. It includes natural collagen and fat loss which contribute to expression lines and sagging skin.
Over time, hormonal changes can cause moisture loss and thinning of the skin.
Although chronological aging cannot be prevented, its progress can be slowed down with injectables, stimulation with collagen and surgical elevators.
Because it is mainly due to lifestyle, environmental aging is avoidable, controllable and correctable.
Contributing factors include sun exposure, smoking, alcohol and poor nutrition.
Aging by the environment can effectively contribute to chronological aging, but with changes in habits, appropriate skin care and resurfacing treatments, to name a few solutions, its signs may be attenuated or reversed.
