John Hopkins Medical Center reported a small study showing that injecting filler, specifically hyaluronic acid, can ease facial paralysis around the mouth.
Hyaluronic acid is a common filler injected into the face to replace lost volume and soften wrinkle lines. Juvaderm, Restalyn and Perlane are a all HA fillers on the market. HA is a precursor to collagen, meaning the body uses HA to make collagen. Collagen is a protein that accounts for 25% - 35% of all protein in the human body and is the primary building block of skin, tendons and ligaments. With aging, collagen loosens everywhere, which accounts for looser skin, ligaments and tendons.
With natural aging, we lose collagen and fat volume in the face. Deep collagen and fat pads support the skin that rests on top of it. With the loss of its underlying support, the skin becomes even more vulnerable to damage from the sun's rays. This accelerated skin damage from the sun is called photo aging. Signs of photo aging includes accelerated wrinkling, sagging, brown spots, red spots as well as skin cell damage that leads to skin cancers.
HA has been used for decades to help slow down the photo aging process. Twice daily application of HA serums to the skin surface can reduce the appearance of fine lines by plumping skin cells. Just like in the plant analogy given in the John Hopkins article, when a plant needs water it looses volume and the stems droop and wrinkle. By injecting HA under the skin, the skin is filled back out making it less vulnerable to photo aging - especially when combined with mineral sunblock and a hat.
HA injections replace lost volume, thus repairing lines and contours around the lips and mouth, along the cheeks, under he eyes, and around the chin and jawline. Fillers can also be used to enhance the lips, cheeks and cheekbones. HA injections last 6-18 months depending on the product used, the location of the injections, and your metabolism.
