Skin ageing shows through lines, skin folds, uneven pigmentation, atrophy, dull complexion and the appearance of pre-malignant and malignant damages due to chronic exposure to ultraviolet rays from sunlight. Skin aging is a challenge for the cosmetic specialist. After the treatment with creams, the deepest lines and folds need a more effective treatment.
We can treat both skin damages caused by formation of lines and damages that alter skin pigmentation -sun blemishes--.
In this section we are going to study all those substances used to fill lines –collagen, biopolymers, etc.— as well as those substances that treat the cause of expression lines –Botox--.
First of all, before infiltrating any product in the lines, it is advisable to start the treatment with a deep cleaning and moisturizing of the skin, followed by a few superficial peels like glicolic acid or medium peels like thricloroacetic acid.
Glicolic acid peel produces gradual exfoliation of the epidermis and therefore removes superficial expression lines. It may induce the production of new collagen in the dermis.
Thricloroacetic acid peel in low concentration coagulates epidermic proteins causing a superficial epidermic exfoliation. These peeling sessions should be repeated for a few weeks, the number of them depending on the problem to be treated.
The diminishing of support tissue is the major cause of lines and facial folds. Among lines and folds, we include nasolabial folds, marionette lines, lip atrophy, crow’s feet and forehead wrinkles. These are treated with injections of substances that fill the dermic defect. The most common substances used for this purpose are collagen, biopoymers and hyaluronic acid.
Injectable materials for the treatment of lines differ among them by their “filling effect”, the duration of the result and their possible side effects.
There are “synthetic materials”, for example biopolymers, that do not require allergy tests and have a long term effect. And there are “biological materials” that require allergy tests and disappear realatively fast.
However, synthetic materials have more risk of body rejection. Normally the treatment must be carried out in a few sessions to guarantee better results.
