Experts from Cosmetic Laser Dermatology, San Diego, California, and Plastic Surgery & Laser Center, Weston, Florida, have recently found that age-related facial volume loss can be effectively treated by using low volumes of hyaluronic acid (HA) filler.
Though hyaluronic acid fillers are most popular anti-aging skin treatment, the filler volumes used in clinical practice vary greatly.
The researchers set out to look at the efficacy, longevity and patient satisfaction associated with midface volume loss treatment through the use of smaller volumes of hyaluronic acid filler.
Important in its impact on the clinical implication of anti-ageing skin treatment, the study was also published in the Journal of American Medical Association, Facial Plastic Surgery on 20th October.
With a large disparity in the volumes used for the treatment, it was noticed that injection volumes of hyaluronic fillers used in initial treatment and touch-up treatments ranged between 6.65 ml and 1.93 ml, 5.1 ml and 2.6 ml, 4.6 ml and 1.5 ml, respectively, in common clinical practice.
Despite the efficacy of these large volumes, it was not known if similar results can be gained through using smaller volumes of fillers. Finding out a threshold for the filler efficacy, it was important to learn if lower filler volumes can be as effective in achieving desired correction or not.
It was not clear why follow-ups were required if initial treatment used large volumes. The longevity of results and their relation with large initial treatment filler volumes were also unclear.
This puzzling pile of questions inevitability led to the question of treatment cost. The cost of larger volume of fillers and repeated treatment follow-ups compared with smaller filler volumes and corresponding treatment follow-ups was also a pertinent concern as both posed a contrasting difference in cost.
The process of aging is natural and it cannot be simply avoided. While keeping ourselves healthy is one way of defying the destructive effects of aging, wrinkles and facial aging effects become points of concern for many as getting rid of them is not easy.
Do Smaller Hyaluronic Acid Fillers Work Equally Well?
During this study, improvement as a result of the treatment was measured on patient-graded Global Aesthetic Improvement Scale. The study participants who underwent this treatment had to respond to the investigation by scoring the scale at 1, 3, 6 and 12 months after treatment.
This study recruited 61 adults with an average age of 57.4 years with mild to severe facial volume loss. While the participants remained predominantly white, African Americans and Hispanics were are also included in the study.
The HA filler volumes given to these participants for the initial treatment was 1.6 ml on average and the touch-up volume on average remained as low as 1.4 ml (touch-up was only opted by 29 people). The number of participants who reported to have experienced much or moderate improvement increased from 73% to 89% while 84% participants reported that they were satisfied with their treatment outcomes.
From this general trend of facial improvement and result satisfaction, the researchers succeeded in showing that smaller HA filler volumes can result in equally good results as given by using larger HA filler volumes.
How Do Hyaluronic Acid Filler Help In Skin Cell Rejuvenation?
The process of aging is accompanied by reduced skin elasticity, collagen (skin protein) degradation and thinning of skin. People who show drastic signs of aging find HA filler injections to be helpful in regaining the lost volume of facial fat pads.
These are dermal fillers which help by acting as an inflated cushion beneath your skin to support facial tissues and structures which have lost their elasticity and volume. They also help in bringing water to the surface skin to give it a radiant look.
HA fillers come with mild side effects which disappear in two weeks’ time. The results last for over two years and the treatment can be conveniently repeating in a clinical setting.
Human body naturally produces hyaluronic acid in connective tissues, fluid around eyes, skin tissues, cartilage and joint fluid. Talking specifically about its role in skin, hyaluronic acid, which is a hydrophilic carbohydrate in nature, provides continuous moisture to the skin and helps in reducing wrinkles and fine lines which are replenished through these fillers.
Other Options For Age Defying Skin
HA filler have many competitors in the market, which include Botox injections, cosmetic surgeries and having other filler injections, such as synthetic fillers including silicone, radiesse and sculptra, autologous fillers and collagen fillers.
While cosmetic surgeries are highly expensive, they remain out of reach for many people. Botox are injected into the facial muscles whose contraction is blocked to reduce wrinkles and fine lines. While these results last for 3-4 months, the bruising, stinging around injection area and facial muscle stiffness are the associated side effects.
Synthetic fillers have a long lasting effects and temporary side effects as bruising and swelling. However, if the procedure is not properly carried out, it can lead to facial disfigurement.
For autologous filler procedure, fat from your body is surgically removed and injected into your face. The procedure is costly, time consuming and requires many sittings.
As it is taken mostly from animal sources, in addition to above mentioned side effects, collagen fillers can cause allergic reactions. So from all the cumulative evidence, HA fillers look to outshine other methods in safety and efficacy.
