Salicyclic acid (up to 30% concentration), glycolic acid (up to 50%)

A

Fine to medium wrinkles, actinic keratoses, dyspigmentation, seborrheic keratoses

32
Q

Does frosting occur with TCA 25-50% peels?

What things do TCA 50% peels address?

A

Fine to dep wrinkles, warts

What is the most common side effect of TCA >50% peels?

A

Depigmentation

37

What are some contraindications to Baker-Gordon peels?

A

Dark skin types, history of cardiac arrhythmias, history of renal or liver disease

42
Q

What are some common side effects of a Baker-Gordon peel?

A

Hypopigmentation, scarring/milia formation

43
Q

What types of monitoring must be had for Baker-Gordon peels?

A

Cardiac monitoring required during and 1 hr postop due to arrhythmia risk

44
Q

What can be done to decrease arrhythmia risk?

A

Wait 15 minutes between treatments of each cosmetic unit to decrease systemic absorption

45
Q

How can renal toxicity be avoided when performing a Baker-Gordon peel?

A

IV fluids –> adequate hydration reduces risk

46
Q

How long does post-operative erythema last after a Baker-Gordon peel?

A

3 months

47
Q

What component is most important for the Baker-Gordon peel (most related to efficacy)?

A

Croton oil

48
Q

Why is it important to ask about radiation therapy to the head and neck when performing a chemical peel/

A

Because radiation therapy reduces the number of pilosebaceous units –> can worsen healing or increase the risk of scarring
