Halloween is all about creativity - transforming into your favorite character with bold colors, glitter, and spooky effects. But while your costume might be temporary, skin irritation from makeup mishaps can last long after the candy’s gone.
At Mt. Lebanon Dermatology, we see a rise in skin reactions every year after Halloween, and most are completely preventable. Here’s how to keep your skin safe while still having fun this spooky season.

🎭 Mistake #1: Using Low-Quality or Expired Makeup
That bargain-bin face paint might look like a great deal, but cheap or old products often contain fragrances, dyes, and preservatives that can cause allergic reactions or breakouts.
✅ Dermatologist Tip: Always check expiration dates and choose makeup labeled “hypoallergenic”, “non-comedogenic”, or “dermatologist-tested.” When in doubt, do a patch test on your arm 24 hours before applying it to your face.
👻 Mistake #2: Applying Makeup to Dirty or Irritated Skin
If your skin is already dry, inflamed, or broken out, heavy costume makeup can make things worse. Bacteria and pigments can settle into open pores or tiny abrasions.
✅ Dermatologist Tip: Start with clean, moisturized skin to create a protective barrier. A lightweight, fragrance-free moisturizer or primer can help prevent irritation and make removal easier later.

🧛 Mistake #3: Skipping the Patch Test
Even “safe” makeup can trigger a reaction — especially if you’re trying a new brand or formula.
✅ Dermatologist Tip: Apply a small amount of makeup behind your ear or on your inner arm and wait 24 hours. If you experience redness, itching, or swelling, skip it.
🕸️ Mistake #4: Sleeping in Costume Makeup
After a long night of trick-or-treating or parties, it’s tempting to fall into bed — but leaving makeup on overnight can clog pores and cause breakouts or dermatitis.
✅ Dermatologist Tip: Remove all makeup thoroughly using a gentle cleanser or micellar water. Avoid harsh scrubbing; instead, follow with a soothing moisturizer to help your skin recover.
🧙♀️ Mistake #5: Using Glitter and Adhesives Unsafely
Loose glitter, spirit gum, and adhesive removers can be harsh on sensitive facial skin. Some glitters contain sharp microplastics that can cause microscopic scratches or eye irritation.
✅ Dermatologist Tip: Use cosmetic-grade glitter only, and apply it with a gel base or balm. Never use craft glitter. Be gentle when removing adhesives — oil-based removers are safest.
