What is the difference between dermal fillers and hyaluronic acid fillers?Aesthetic Medicine
What is the difference between dermal fillers and hyaluronic acid fillers, eg. Ellanse vs Juvederm? Which is better, and is there any difference in their safety profiles?
Dermal fillers refer to a variety of substances that can be injected into the skin for filling in creases and lines, enhancing facial contours and plumping up the lips and cheeks. The term "Dermal" actually refers to the dermis layer of the skin and is the layer which fillers are most appropriately injected into. However dept of injection is dependent on filler type and anatomical location of injection.
Hyaluronic acid (HA) fillers refers to fillers made of hyaluronic acid (Juvederm, Restylane). HA is a naturally occurring substance in the skin . It has the ability to draw and retain large amounts of water, allowing it to restore lost volume and hydrate the skin.
Not all fillers are made of HA. Other substances used to make fillers include calcium hydroxyapatite(Radiesse) and polycaprolactone (Ellanse) . Each filler has its own indications of use and safety profile. Choice of filler for use also depends on physician preference and familiarity with the product. It is best to discuss with your treating aesthetic physician regarding which filler is best for you.Regards,
Yes, there are so many different fillers on the market and I understand it could be confusing understanding them and deciding which, if any at all, is best for you. Dermal fillers are a gel-like soft tissue filler injected into the skin.
It can help with many things, including facial augmentation, diminishing facial lines and also restoring the volume and fullness in the face. The word "dermis" is a medical technical term that refers to a layer of the skin (below the epidermis, and above the layer of subcutaneous tissue) - you may refer to the diagram below for a reference.
The reason for coining the term "dermal fillers" stems from most fillers being most appropriately injected into the dermis layer of the skin. Fillers can be injected in the upper, mid or deep dermis layer of the skin depending on factors such as facial anatomical location and filler type, for example.
As for the term "hyaluronic acid filler", this refers to a filler made of the material hyaluronic acid. Hyaluronic acid is also known as the skin's "moisture molecule" as it is able to absorb up to 1000x its own weight of water, hence giving it the ability to lift and restore volume and hydration to our skin and tissues.
A dermal filler may be made of hyaluronic acid (such as fillers of the brand Juvederm), or made of other non-hyaluronic acid materials such as polycaprolactone (Ellanse) or calcium hydroxyapatite (Radiesse). Juvederm and Ellanse are brand names of fillers.
As for specific differences such as which is better, and differences in safety profiles, these will probably be better discussed in person by your physician who can go into a more detailed consult with you. Hope to have shed some information on fillers for your consideration!
