What is the primary method used during advanced extractions?

The primary method used during advanced extractions is the use of lancets or needles. This technique allows for precise and controlled extraction of impurities, such as blackheads or clogged pores, particularly in cases where manual extraction might be ineffective or could cause trauma to the skin. Lancets and needles are tools that can create small, controlled incisions, providing access to the underlying skin layers where impurities reside. This method is often employed in professional settings, ensuring that the extractions are done safely and hygienically, which is crucial for minimizing the risk of infection and skin damage.

Other methods, such as gloved fingers and cotton swabs, can be useful for gentler extractions, but they do not offer the same level of precision as lancets or needles. Mechanical devices may assist with extractions in some circumstances, but they are not the primary method for advanced techniques. Chemical solutions can help in preparing the skin or in treating conditions, but they do not directly facilitate the extraction process in the same way that lancets or needles do. Therefore, the correct choice highlights the specific and specialized approach used in advanced extraction procedures.
