Check where the bumps show up

The easiest way to tell is to look at where the bumps are appearing and whether your skin feels tight or dry anywhere else.

Closed comedones from a too-heavy moisturizer are small, skin-colored bumps that feel like sandpaper or tiny grit. They typically cluster on your forehead, chin, or jawline — areas that already produce more oil. If your skin is bumpy in those zones but feels fine everywhere else, the moisturizer is likely too rich for that area.

If the problem is that your moisturizer isn’t occlusive enough for winter, you’ll feel the opposite: dry patches, tightness, flaking, or a “windburn” sensation, especially on cheeks and around the nose. Your skin might feel okay when you first apply it, but an hour later it’s tight again. That’s the moisturizer evaporating too fast because it lacks a true occlusive ingredient like petrolatum, dimethicone, or lanolin.

One other clue: timing. Closed comedones take days or weeks to develop. Dryness from poor occlusion shows up within hours or after one day in cold, dry air.

If you’re still unsure, try a simple test: skip your current moisturizer for two days and use only a very light hydrating gel or serum plus a thick occlusive layer (like plain petroleum jelly) at night. If the bumps vanish in a few days, it was comedones from the heavy cream. If your skin gets tight and unhappy, you actually need more occlusion, not less.

Trust your skin, not the label.
