The treatment effect that is associated with increased product penetration is related to the process of applying indirect high frequency. Indirect high frequency involves using a high-frequency current that is applied in a way that stimulates the skin without directly touching it. This approach creates a warm, relaxing sensation that can stimulate circulation and promote the penetration of serums and other skincare products deeper into the skin.

The gentle heat generated during indirect high frequency also opens the pores, making it easier for active ingredients to be absorbed more effectively. This allows estheticians to enhance the efficacy of products applied during a facial treatment by ensuring they reach deeper layers of the skin.

In contrast, direct high frequency is typically used for its antiseptic properties and is applied directly to the skin, which may not emphasize product penetration as much. Desincrustation focuses on deep cleansing and removing impurities rather than enhancing product absorption. Microdermabrasion, while excellent for exfoliation, primarily removes the outer layer of dead skin cells and might not necessarily increase the penetration of products to the same extent as indirect high frequency.

Understanding the specific effects of these treatments helps estheticians tailor their services to meet client needs effectively.
