What is Skin Rejuvenation?
As an effect of ageing, somatic cells in the body lose their ability to divide and the total number of these cells gradually diminishes. This reduction in the number of cells of the epidermis and the dermis results in the skin losing its tone and elasticity which leads to the appearance of wrinkles.
These changes may be due to internal factors such as increase in age, a decline in the body’s rate of metabolism and various genetic factors like hormonal imbalances and congenital skin changes. They may also be due to external factors like climate, environmental exposure, diet, and others, which may cause an accumulation of harmful elements in the human body.
Skin rejuvenation is a way to reverse the effects of aging by inducing controlled wounds on the skin, prompting it to heal itself by creating new cells. This is done by the use of lasers, the Etherea IPL-sq, radiofrequency, other thermal methods or photodynamic therapy.
What are the available options for Skin Rejuvenation?
There are three basic categories of devices that can be used for skin rejuvenation – Laser, Intense Pulsed Light, and Radiofrequency. Although different technologies are utilised in each of these devices, using completely different methods and producing different after-treatment effects, the end results are all the same – the production of new skin cells by the body to replace old ones.
For instance, non-ablative lasers like the Pastelle and intense pulsed light systems like the Etherea utilises specific wavelengths that target deeper tissue to induce heating and the stimulation of collagen. This in turn improves the foundation under the superficial layers of the skin and induces a tighter and fuller look, getting rid of fine lines and wrinkles. Ablative lasers like the Fraxis work more superficially, treating the epidermis and eliciting the production of new epidermal cells.
Radiofrequency (RF) devices such as the Secret RF may be used to achieve both effects. A bi-polar fractional hand piece can mimic the effect of an ablative laser to the epidermis, but does so in a more controlled manner, often called a sub-ablative effect.
Newer devices like the Secret RF utilise the combination of radiofrequency and micro needling to deliver heat more precisely to a specified depth of the skin, at the same time avoiding any thermal damage to the epidermis. This thermal effect induces skin regeneration by collagen and elastin proliferation in the dermis, eventually remodeling this layer and resulting in new, tight and supple skin over a number of weeks.
