Hyaluronic acid injections stimulate long-lasting collagen renewal in aged skin
Chronic exposure of human skin to ultraviolet light causes premature aging, or photoaging. As the skin undergoes photoaging, type I collagen bundles, which are found in the dermis beneath the top layer of the skin and provide strength and support to skin, become fragmented. This leads to wrinkles, fragility and loss of support and elasticity.
Reversing time: Hyaluronic acid injections offer lasting improvement in aging skin
The fragmentation of type I collagen has been seen to impair the integrity of the dermal extracellular matrix (ECM). This results in lower type I procollagen synthesis and contracted or collapsed fibroblasts. A recent Experimental Dermatology study assessed how these deleterious changes could be reversed by injecting cross-linked hyaluronic acid (CL-HA).
New study examines dermal injections and their impact on skin aging
Experts observed in a new study published in Experimental Dermatology that injection of the most popular type of dermal filler, cross-linked hyaluronic acid, into photoaged skin could reverse the dermal changes associated with photoaging.
Dermatology researchers create new tool to measure hyperpigmentation
There are currently no globally accepted methods for analyzing hyperpigmentation, a condition in which patches of skin are darker than the surrounding skin on the body. While one popular scale exists, it is specific to facial hyperpigmentation related to acne.
How to identify and treat a herpes skin rash
Infection with the herpes simplex virus (HSV) can lead to a skin rash. Early signs include burning and tingling, after which sores appear that can turn into blisters or pustules. Treatment with antiviral drugs may shorten the healing time.
