Collagen, a naturally occurring protein in the body, is the substance responsible for keeping skin strong and supple. The use of this protein in collagen injections created the first dermal fillers on the market. Originally, bovine collagen or animal-derived collagen was used in the injections, but current treatments can use bovine or human collagen.
Collagen injections treat the same facial wrinkles that BOTOX® Cosmetic does, including frown lines, crow's feet and forehead creases. Collagen injections can also be used to compensate for fat loss in facial tissues, lip augmentation, and to fill in acne scars or dark under eye circles. While bovine collagen injections like Zyderm and Zyplast are still used today, patients are required to undergo a skin test prior to treatment to ensure against allergic reactions. By comparison, human collagen injections like CosmoDerm and CosmoPlast can cost more, but they are proven non-allergenic treatments.
Botox injections don't technically qualify as a dermal filler because their treatments use the botulinum toxin type A, a neuromuscular blocking toxin, rather than a filler substance. The botulinum toxin relaxes tense facial muscles so that the appearance of wrinkles and fine lines is temporarily eliminated. Botox is FDA approved for the treatment of wrinkles and poses the risk of a few minor side effects like temporary bruising. Overall, Botox and collagen injections are considered safe procedures for the majority of patients.
The cost of Botox injections is usually the lowest among all dermal injectables. Comparatively, the cost of collagen injections is typically higher, with human collagen injections often being more expensive than bovine collagen injections. Be sure to look up cost averages in your area, and choose a provider that offers treatments at competitive costs.
Whether you're interested in Botox injections or collagen injections, it's best to meet with a treatment provider in your area first to undergo skin analysis, ask detailed questions about each procedure's risks and benefits, and to select the treatment best suited to your needs.
