  • Dermal filler vs. collagen injections – what’s the difference?

Dermal Filler and Collagen injections MelbourneIt might have been a while since you heard about collagen injections, because dermal fillers have all but taken over in effectiveness, longevity, and safety. Now, your cosmetic dermatologist is more likely to offer you dermal fillers, not collagen, but why the change? Turns out, newer dermal fillers are generally just better at everything. 

The differences between collagen and dermal fillers

  • Collagen does not last as long as newer dermal fillers
  • Allergic reactions are more common with animal-derived collagen injections
  • Dermal fillers are the synthetic version of a molecule already found in skin, and much safer

How long do dermal fillers and collagen last?

Once injected, collagen from cows lasts between two and three months, while its dermal filler counterpart can last – depending on the area treated – from three to nine months.

The parts of your face that either injection treats may differ, for example collagen is more often used for superficial, deep wrinkles and fine lines, or scars, whereas dermal fillers may have more uses, often used for specific filling areas like lips or cheeks, or around the eyes. They are both used for the same purposes, more or less, but there are trends.

Why dermal fillers are a step up (most of the time)

  • No skin tests required
  • Better affinity for human skin
  • Substances are smooth and easy to inject for a natural look
  • Works on any skin type or tone

How collagen injections work

The dermis, the second layer of your skin from the top, contains blood vessels, nerves, hair follicles, and collagen. Collagen is also found in connective tissue like bones, cartilage and teeth. The collagen from the injection is readily accepted into your skin’s structure as your own (except in cases of allergy) and helps boost your natural skin tone and supports. Over time, however, collagen injected will start to degrade like normal collagen, requiring replacing. Collagen injections are likely to be required four times per year for maximum effect.

Collagen is the structure underneath your skin that holds you up and together, consisting of a network of fibres within which cells and blood vessels exist. Collagen treatments are used to rejuvenate sun-damaged skin, where the collagen and elastin has been damaged, and to compensate for ageing skin, which naturally produces less collagen. Scars can also be treated using collagen injections.

Cosmetic collagen became big in the 80s and 90s, delivered with large needles. Some collagen injections were actually comprised on your own collagen, which was harvested, liquified, and then injected back into you. This was called autologen.

Results with collagen injections weren’t as good as dermal fillers are now, and allergy rates were about three per cent, which is high and very unpleasant to experience. Almost nobody uses collagen injections anymore, since we now have safe substances, which is unequivocally better in every way.
