Prodermic 421 is a 4-agent detoxification system built around Black Acetic Acid (10%) for deep impurity extraction, combined with a tri-acid purification complex for comprehensive congestion clearing and skin renewal. The BAC-4D Complex pairs Black Acetic Acid's activated carbon-like drawing properties with Salicylic Acid (15%) for deep pore decongestion, Mandelic Acid (10%) for uniform antibacterial penetration, and high-dose Lactic Acid (30%) for intense hydrating exfoliation with skin barrier support.

BAC-4D Complex — A black acetic acid-led detoxification system with quad-acid purification and deep lactic acid hydration.Black Acetic Acid (10%) works as a deep-drawing purification agent, extracting environmental pollutants, oxidized oil, and trapped impurities from the skin like activated carbon. Salicylic Acid (15%) penetrates into oil-rich pores to dissolve acne plugs. Mandelic Acid (10%) provides broad-spectrum antibacterial coverage with even penetration.High-dose Lactic Acid (30%) drives intense hydrating exfoliation while supporting skin barrier repair and moisture production.

If desired results are not achieved, it does not indicate the peel is ineffective—it may simply mean that the skin has a higher tolerance to the current formulation. In such cases, consider transitioning to a stronger peel, applying multiple coats, or increasing the application time in subsequent sessions.
