Best way to protect yourself from developing skin cancer• Move into a cave• Move to Seattle• Stop living your life
What are the types of skin cancer
• Actinic keratosis• Squamous cell carcinoma (SCC)• Basal Cell Carcinoma (BCC)• Melanoma
Non melanoma skin cancers
• Superficial BCC and SCC• Topical therapies
• 5 fluoracil• Aldara• Photodynamic therapy
Mohs surgery
• Advantage of Mohs• Indications for mohs• Cosmetic areas• Greater than 2 cm body • Greater than 1 cm face• Recurrence• Sclerosing bcc
Radiation therapy
• Non surgical candidates• Poor wound healing• Limited options for further surgery
Prevention techniques?
• Sun protective clothing• Sunscreen• Skin exams• Avoid peak hours of the day

Ultherapy, Sublime, Sublative, Vela, Cool sculpting
• The basic premise of most of these devices is the same • Deliver energy into the skin • Wound healing response = neocollagenesis= tissue tightening
Ultherapy
• Focused Ultrasound• FDA approved for LIFTING• Bypasses skin surface and targets deeper tissue where
collagen lives• Works from the inside-out
Ultherapy
• Delivers tiny deposits of focused ultrasound energy at the same layer that a facelift typically addresses• Coagulation points=Stimulates the growth of new collagen• Can vary depth 4.5, 3, 1.5 mm
Ultherapy
• Minimal downtime• Gradual tightening and lifting of skin over 90 days• For the post surgical, non-surgical pt, and preventative pt• Expectations
sublime
• An electrical current that is not chromophore specific• Epidermal melanin is not damaged/color blind• All skin types• Heat accumulation= production of new collagen
sublime
• The RF current has preference for pre-heated targets • The epidermis is cooled by the chilled applicator tip protecting
the epidermis• Forcing the RF energy to penetrate deeper into tissue
Sublative RF
• Fractionated RF delivered via 64 electrodes on applicator tip• Deep dermal heating= induces injury = induces healing process =
neocollagenesis
Sublative
• 5% epidermal ablation• Dispersed heat to dermal layers (30% dispersion)• All skin types• social downtime (2-3 days) • 3 treatments needed
Velashape 3
• Powered by elōs technology, VelaShape III combines IR (infrared), bi-polar RF and vacuum • Deep heating of the fat cells (adipocytes), their surrounding
connective fibrous septae and the underlying dermal collagen fibers
result
• A localized reduction in skin laxity, volume and an overall improvement in skin structure and texture.
