What are the contraindications for ultrasonic treatments?
Heart conditions, pacemakers, pregnancy, and diabetes.
What is the purpose of cavitation in ultrasonic treatments?
Cavitation is a cleaning step that creates the implosion of a water molecule.
What is sonophoresis used for in ultrasonic treatments?
Sonophoresis is used to penetrate serums and moisturizers into the skin.
What does microcurrent do in ultrasonic treatments?
Microcurrent is used to create homeostasis balance in the skin.
What are the contraindications for microdermabrasion?
Rosacea, bacterial/viral/fungal infections, open lesions, dermatitis, active acne, use of Accutane
within 1 year, and immediate post-operative conditions.
What types of materials can be used in crystal microdermabrasion machines?
Aluminum oxide (corundum), salt, and baking soda.
What factors can affect the aggressiveness of a microdermabrasion treatment?
The strength of the crystals, speed of the handpiece, and number of passes.
What should be monitored during a microdermabrasion treatment to avoid complications?
Settings should be charted, and services should stop before the appearance of erythema.
,What are the contraindications for chemical peels?
Use of retinoids, herpes simplex, open lesions, pregnancy, heart conditions, eczema, lupus,
rosacea, psoriasis, infections, extremely thin or sensitive skin, and sunburn.
What is the typical concentration range of acids used in salon chemical peels?
15-30%.
Which acids are commonly found in chemical exfoliants?
AHA (Alpha Hydroxy Acid) and BHA (Beta Hydroxy Acid).
What are the components of a Jessner solution?
Salicylic Acid, Lactic Acid, Resorcinol, and Ethanol Base.
What happens during a TCA chemical peel when a full frost is achieved?

What safety measure should be taken regarding the eyes during laser treatments?
The lens of the eye can magnify laser energy by 100,000 times.
, What is photothermal reaction in laser treatments?
It is where the chromophore absorbs laser energy and is transformed into heat, killing the target.
What is photorejuvenation?
A nonablative process using laser or light devices to increase collagen and elastin and improve
vascular and pigmented lesions.
What is photodynamic therapy?
A stand-alone treatment that uses a combination of light (LED or IPL) with aminolevulinic acid
(ALA).
What is the purpose of skin cooling during laser treatments?
To protect the skin and enhance comfort during the procedure.
What is the role of photomodulation in light therapy?
It uses low-level light energy to modulate or activate cellular metabolism.
What is photomodulation?
A process using light devices to trigger a photobiochemical response, involving low-level light
energy to modulate cellular metabolism (LED therapy).
What is a phototoxic reaction?
A tissue reaction that occurs in the skin when combining ALA with light therapy.
What is the wavelength of Alexandrite laser and its chromophore?
755nm, with melanin as its chromophore.
