Hyaluronic acid fillers found to stimulate collagen production in photoaged skin

dermal fillers collagen stimulation

Fine lines and wrinkles, sagging skin, hollowing at the temples and under the eyes, flattening of the cheeks and loss of definition along the jawline, are all indicators of facial volume loss that occurs as we age. Partly this is due to the depletion of collagen, but also loss of facial fat both underneath the skin’s surface and in the deeper fat pads.

Hyaluronic acid dermal fillers have long been one of the most popular aesthetic treatments for their ability to add volume and soften lines. HA is a sugar molecule that is naturally found in the body; in the dermis it attracts a thousand times its own weight in water so is responsible for keeping your skin plump and hydrated.

The hyaluronic acid used in dermal fillers is slightly modified so the body takes between six months and up to two years to degrade it, depending on where it is placed. HA fillers are now available in different consistencies and firmness, so some are suitable for building structure such as in the chin or jawline. Softer fillers are used to add volume in the lips or cheeks.

Dermal filler benefits

Now, a new study has found that hyaluronic acid dermal fillers not only add volume to the skin but can also boost collagen production.

Researchers at the University of Michigan Medical School studied the mechanism behind skin changes on a cellular level due to photoageing and the effects of HA dermal fillers. They found the fillers stimulated the production of new type I collagen in photoaged skin within several weeks of injection, and the results were long-lasting, promoting the accumulation of more collagen over the course of a year.

Collagen production may be a secondary action of dermal fillers but Polynucleotides is an anti-ageing treatment whose primary action is collagen stimulation. Polynucleotides are filtered and ultra-purified natural DNA fractions that initiate your body’s natural fibroblast production, resulting in increased collagen (47% in 23 days) and a thicker, healthier epidermis (52% in 23 days).

What is skin photoageing?

Chronological ageing, also known as intrinsic ageing, are the changes that occur naturally over time. Closely interlinked with chronological ageing is extrinsic ageing which are the many external factors that accelerate the natural ageing process.

This can be down to smoking, stress, poor diet and lack of sleep, but the main culprit is sun exposure or photoageing. In fact, it’s believed that 90% of the signs of skin ageing are due to sun exposure. UVB and more importantly UVA rays penetrate the dermis and cause damage to the skin cells and oxidative stress that breaks down the building blocks of the skin such as collagen, elastin and hyaluronic acid.

As well as loss of elasticity and firmness and the formation of lines and wrinkles, photoageing is responsible for pigmentation changes, age spots, and uneven skin tone.

The best way to prevent photoageing is to regularly use a high factor SPF, but if you’ve started to notice unwelcome changes to the skin due to sun exposure, there are several treatments that can help, including dermal fillers.
