Hypertrophic scars (raised scars)
Definition:
An abnormality in the healing process of the skin after an injury, characterized by a slight relief from the normal level of the skin. Reversible, it ends up changing its appearance gradually over time. The formation of these marks is explained by an excessive production of collagen to repair the dermis. The amount of fibrous tissue in the healing process is so dense that it deforms the scar to the point where it increases significantly in volume. However, in some cases, the hypertrophic scar does not disappear and, on the contrary, it gets worse, i.e. it exceeds the limits of the initial lesion, caused by a continuous and abnormal proliferation of collagen fibers: this is called a keloid scar.
Internal and external causes:
Acne pimples, insect bites, skin injuries.
How to reduce or eliminate:
There are different treatments in aesthetic medicine that can reduce hypertrophic scars and help them to disappear: intralesional injection of corticoids, skin ablation, radiotherapy, laser treatment (CO2 laser, Erbium laser), pressotherapy, dermatological peeling. It is also possible to use fruit acid-based cosmetics (AHA, BHA, PHA), but this procedure will require several applications to obtain visible results.
Preventative steps to take:
Avoid popping pimples. Consult a dermatologist to obtain adequate treatment to fight acne. Apply a moisturizing cream regularly to keep the skin supple. Avoid the sun; protect the skin from the sun's rays by applying an SPF 30 cream at least every time you are exposed to the sun. Even with proper care, it is not always possible to avoid the appearance of hypertrophic scars.
