About this ingredient list
The ingredients listed are some of the most commonly associated with pore congestion in acne-prone skin. They tend to be heavier, more occlusive, or lipid-rich, which can make it easier for oil, dead skin cells, and debris to become trapped inside the pore.
Not everyone will experience breakouts from these ingredients. Skin reactions depend on the full formula, quality of the ingredient, concentration, frequency of use, and individual skin type. This list is meant to be a helpful reference — not a definitive rule for every product or every person.
