**Question:** Chemical peeling is done by all except:
A. Salicylic acid
B. TCA (Trichloroacetic acid)
C. Mandelic acid
D. Resorcinol
**Core Concept:** Chemical peeling is a skin rejuvenation procedure that uses various chemical substances to improve skin texture, tone, and appearance. It involves applying chemicals to the skin, which cause controlled damage to the epidermis and/or dermis, resulting in skin renewal and rejuvenation.
**Why the Correct Answer is Right:** Resorcinol is not commonly used for chemical peeling due to its high toxicity and potential side effects. It is a phenolic compound used primarily in industrial applications and as a reducing agent in organic synthesis. In contrast, salicylic acid, TCA, and mandelic acid are commonly used agents for skin peeling, as they are milder and have fewer side effects.
**Why Each Wrong Option is Incorrect:**
A. Salicylic acid is a beta-hydroxy acid (BHA) derived from willow bark and is commonly used in skin peeling procedures. It is a safer and milder agent compared to other peeling agents, making option A incorrect.
B. TCA (Trichloroacetic acid) is a common alpha-hydroxy acid (AHA) used for skin peeling. It is a stronger agent than the other options, making option B incorrect.
C. Mandelic acid is a hydroxy acid derived from bitter almonds and is a milder agent compared to TCA and salicylic acid, making option C incorrect.
**Clinical Pearl:** When selecting a chemical peeling agent for a patient, consider factors such as peeling strength, potential side effects, and the patient's skin type and condition. A balanced decision should be made to achieve the desired outcomes while minimizing adverse effects.
