    "**The last layer changes the experience:** Slugging uses an occlusive layer to reduce moisture loss. Forum replies include softer-feeling skin, greasiness and breakouts; some also report irritation when combining the layer with other active skin products. Those are distinct outcomes, so a before-and-after photo does not answer every reader’s question about tolerance. [community]",
    "**The jar is not the whole routine:** Petroleum jelly is one occlusive option, while branded ointments may contain other ingredients. The AAD notes its usefulness for moisture retention and cautions that it can cause breakouts on acne-prone skin. The product ingredients and what is layered underneath it both matter when comparing accounts of the night-time skin-care step. An occlusive layer is a different product role from a peel or an active medicine such as tretinoin. [professional]"
