HA Dermal Fillers - Everything You Need to Know

Looking for a way to eliminate wrinkles and signs of aging or correct minor facial blemishes without invasive surgery? Dermal fillers might be the solution you're looking for. In general, injectable fillers to be classified as a class III medical device with CE marking must:

- Meet stringent safety and tolerability criteria, namely sterility, stability, biocompatibility, non-immunogenicity, non-pyrogenic, easy injectability, and non-invasive;

- Injection only by authorized medical personnel (plastic and cosmetic surgeon).

The multitude of fillers on the market varies in biological and chemical-physical properties, making selection difficult. For this reason, it is important to share information with your doctor to make an informed choice.

Resorbable Fillers: consist of substances that do not have a permanent effect when injected into the dermis (superficial, medium, or deep), such as those based on hyaluronic acid or collagen. This means that once injected, the product is gradually metabolized and then reabsorbed by the body at different times depending on:

– The type of preparation used;

– The treatment area;

– Many personal factors (eg lifestyle, smoking, strenuous exercise, regular exposure to UV radiation).

The advantage of absorbable fillers is their gradual action, i.e. they gradually adapt to changes in facial features;

Non-absorbable Fillers: derived from polymers with alkylamine and polyacrylamide linkages, while having permanent effects, they have and will continue to create problems and complications. In addition to the risks of infection, granulomas, and skin fistulas, permanent fillers implanted in the soft parts of the face do not adapt to the evolution of the surrounding untreated tissue, causing serious dissonance over time. That's why the scientific community is increasingly turning against them in favor of slow-absorbing fillers.

Hyaluronic acid is a polysaccharide that is already naturally present in the human body, but its natural production tends to decrease as we age. Found in the vitreous humor of the eye, until recently it was extracted from animals, notably from the crest of roosters. Today, poultry-derived hyaluronic acid has been replaced by a non-animal-derived hyaluronic acid produced exclusively through bacterial fermentation.

Hyaluronic acid fillers help fill in lost volume, reduce expression lines and nasolabial lines, and add volume to existing ones, such as thin lips or sagging cheekbones. Certain types of injections can also treat larger body areas, such as the lower legs and buttocks, while fillers in the breast area are strictly off-limits, as the substance can interfere with proper screening for breast cancer.

In general, they help to deeply moisturize the skin, rejuvenate, radiate, refresh, and stimulate collagen production. Injectable fillers are also increasingly used to correct facial incongruities, such as the contouring of the nose (called nasal fillers), in place of plastic surgery, although the results are not permanent.

Hyaluronic acid fillers are further divided into three subcategories:

Low-density fillers for superficial wrinkles and faster absorption;

Medium-density fillers for deeper wrinkles (such as nasolabial or marionette lines);

High-density fillers, also known as volume fillers, are applied to supportive areas like the cheekbones and chin.

If you are considering treatment with hyaluronic acid-based fillers, remember to always entrust only authorized healthcare professionals who will be able to guide you in making the most suitable choice based on your physical characteristics and health status.
