Which treatment is effective for deep cleansing and preparation of the skin before extractions?

Desincrustation is an effective treatment for deep cleansing and preparing the skin before extractions because it specifically targets oil and debris trapped within the pores. This method typically involves the use of an alkaline solution or a special machine that uses galvanic current to soften sebum and blockages. By breaking down these impurities, desincrustation makes it easier for practitioners to perform extractions safely and effectively.

In contrast, hydration masks primarily focus on moisturizing the skin, which, while beneficial, does not address deep cleansing or preparation for extractions. Exfoliative scrubs can remove dead skin cells but might not effectively penetrate or cleanse deeply enough to facilitate extractions. Oxygen therapy, while promoting skin rejuvenation and delivering oxygen to the skin's surface, does not have a direct role in deep cleansing or preparing the skin for extractions. Thus, desincrustation stands out as the most suitable choice for this purpose within the context of the question.
