The use of nonabsorbable sutures for lifting lax, aging skin is an increasingly popular option for cosmetic surgeons. Contour Threads™ (Surgical Specialties Corp.) are novel modified polypropylene sutures recently approved for this purpose by the US FDA.
Photodynamic therapy has been used for several years for the treatment of actinic keratoses and prevention of invasive nonmelanoma cancers. Recently, increasing physician expertise with the topical sensitizers and light sources employed in PDT has led to expanded applications.
Changes in the skin that occur in the elderly may put them at increased risk for altered percutaneous penetration from pharmacotherapy along with potential adverse effects. This overview discusses the current data of studies to evaluate the impact of skin factors in age-related percutaneous penetration.
A number of research studies have documented the link between diet and skin aging. These results may be used to develop dietary recommendations that combat the forces of oxidation, inflammation, and glycation.
Given our current options for the treatment of Seborrheic Keratoses include only more invasive, non-topical therapies, Hydrogen Peroxide Topical Solution (40%) fills a void in our therapeutic repertoire as the first FDA-approved topical therapy for SKs.
Why is it that some people (other people!) seem to age slower? It's not fair! Plastic surgeon Dr. Bryce Cowan explains the complexities and factors that affect the timeline of aging, in the first part of the Science of Facial Aging series.
Several formulations of botulinum toxin type-A (BoNT-A) are on the market in North America. This article discusses formulations, and differences in pharmacokinetics, and how it affects indications.
The botulinum neurotoxins (BTX) are an exciting group of therapeutic agents with dramatically expanding clinical indications. The US FDA has approved BOTOX® (BTX-A, Allergan) and Myobloc™ (BTX-B, Elan Pharmaceuticals) for the treatment of cervical dystonia.
The development of topical cosmetic anti-aging products is becoming increasingly sophisticated. This article reviews trials that look at the efficacy of cosmetic (OTC) products against prescription products.
What are the advantages of cosmetic surgery over soft procedures like Botox and dermal fillers? The main advantage is that cosmetic surgery allows for a more profound and long lasting correction that's not possible with other treatment options.
The ideal candidate depends on the specific treatment, but in general terms, we are looking at a patient who is a healthy, non-smoker, does not have high blood pressure, does not require anti-coagulants, is in their late 40s or early 50s, where the impact of the surgery is highest.
What cosmetic procedures might be useful for a given patient? The two key principles of aging of the face are volume loss and tissue malposition. There are many elements changing simultaneously, so it's very rare that there is an effective singular procedure that can act as a fix all solution.
Psoriasis, acne vulgaris and photoaging are common conditions. Tazarotene is a pro-drug of tazarotenic acid, a receptor-selective retinoid, which has shown efficacy in the treatment of these disorders. In the treatment of acne vulgaris, it has greater comedolytic activity than the currently available topical retinoids.
Cosmetic products containing ultraviolet light filtering agents are rapidly being developed and entering the marketplace. This article reviews formulary attributes, effective photoprotection, adherence, and behavior modification.
The success of botulinum toxin type A (BOTOX®, Allergan Inc.) in the cosmetic arena has acted as a stimulus for the development of other neurotoxins. Herein, we present an overview of botulinum toxin products for cosmetic applications that have received regulatory approval or are under development.
The formation of free radicals is a widely accepted pivotal mechanism leading to skin aging. Topical antioxidants are available in multivariate combinations through over-the-counter skin care products that are aimed at preventing the clinical signs of photoaging.
Age-related Percutaneous Penetration Part 2: Effect of Age on Dermatopharmacokinetics and Overview of Transdermal Products
Transdermal drug delivery allows for a constant rate of drug administration. This second part highlights the importance of elderly patient care, and consideration for patients who may be using multiple drug treatments.
Photoaging is a multisystem degenerative process that involves the skin and the skin support systems, including the bone, cartilage, and subcutaneous compartments. These structures provide the architectural support for the dermis, epidermis, and stratum corneum.
Patients need to be able to both understand and accept the risks of surgery. It's a balance between their motivation and desire to undergo surgery and their willingness to accept the risks involved with that procedure.
Genetic predisposition to melanoma and nonmelanoma skin cancer extends far beyond the Fitzpatrick phenotype classification scheme. Testing aimed at improving prognostication may serve to limit the influence of certain risk factors.
Increased accumulation of AGEs in human tissue has been associated with serious medical concerns including end stage renal disease, chronic obstructive pulmonary disease, and, recently, skin aging. In this review, we summarize the evidence supporting the role of glycation in skin aging.
Photoaging and skin damage that is caused by solar radiation is well known. IRA acts via the mitochondria and therefore protection from IR requires alternative strategies.
Sirolimus, also known as rapamycin (SRL, Rapamune®), was approved in 1999 by the US Food and Drug Administration to prevent graft rejection in renal transplantation. This articles reviews Sirolimus, its pharmacokinetics, mechanism of action, and indication.
Platelet-rich plasma (PRP) is an autologous serum containing high concentrations of platelets and growth factors. PRP continues to evolve as an important treatment modality with many applications in dermatology, particularly in the areas of hair restoration, skin rejuvenation, acne scars, dermal augmentation, and striae distensae.
