Patch Test Checklist

Use the inner forearm or behind the ear — easy to check and cover if needed.

Wash with plain water, pat dry, and avoid other products on the test area.

Use a pea-sized amount of a single product you have not used before.

Look for stinging, burning, redness, itching, or swelling.

Some reactions appear slowly; compare the patch to surrounding skin.

Note any bumps, dryness, or persistent redness.

Keep the rest of your routine unchanged while testing.

Contact dermatitis can take several days to show.

If irritation appeared, stop using the product and rinse the area.

No reaction? Introduce slowly. Any reaction? Do not use on your face yet.
