Which ingredient is often included in disincrustation lotions to aid in deep cleansing?

Sodium bicarbonate is commonly included in disincrustation lotions because of its alkaline properties, which help to soften and emulsify sebum and other impurities within the pores. This ingredient works particularly well in facilitating deep cleansing by breaking down oil and debris, making it easier to cleanse the skin effectively. The alkaline nature of sodium bicarbonate raises the pH level of the skin temporarily, which can aid in dissolving the congestion within the pores, thus allowing for a more thorough clean and preparing the skin for subsequent treatments.

In contrast, salicylic acid, which is often used for its exfoliating properties and effectiveness in treating acne, primarily works as a chemical exfoliant rather than specifically for deep cleansing in the same way that sodium bicarbonate does. Glycolic acid, while also an exfoliant, primarily helps in removing dead skin cells from the surface rather than necessarily targeting the deeper layers of the skin's congestion. Vitamin C is a potent antioxidant that helps brighten the skin and provide anti-aging benefits, but it does not have the same role in deep cleansing as sodium bicarbonate. Thus, sodium bicarbonate stands out as the most effective ingredient specifically designed for the deep cleansing function within disincrustation lotions.
