Before administering a Jessner peel, what preparation step should be taken?

Prior to administering a Jessner peel, stripping the skin of oil with acetone is a vital preparation step. This process helps to remove excess oil, makeup, and any other superficial debris that could interfere with the penetration of the peel solution. By ensuring the skin is clean and free of barriers, it allows the Jessner peel to work effectively on the skin's surface and deeper layers, optimizing its ability to exfoliate.

Using acetone is particularly effective because it quickly evaporates and leaves the skin in a condition that is ready to absorb the chemical peel. This thorough cleaning prepares the skin to undergo the chemical action of the peel, which is designed to treat conditions like hyperpigmentation, acne, and signs of aging.

While other options, such as applying protective creams or moisturizers, may seem appealing, they could obstruct the effective application of the peel. Ensuring the skin is wet is also not a typical step needed for a Jessner peel, as chemical peels are usually applied to dry skin to facilitate better adherence and absorption of the active ingredients. Thus, using acetone to strip the skin of oil ensures a more effective and safer treatment process.
