Patch Testing Guide
What is a patch test?
Got new skincare? Hold on! Perform a patch test first, as it allows you to check skin compatibility and identify any ingredients or fragrances that your skin might react to. It’s simple, easy, and perfect for knowing if it’s a match or a mismatch.
Ampoule Serum
Clean a small area behind your ear or on your inner forearm or wrist.
Apply 1–2 drops of the Ampoule Serum.
Leave it on for 24 hours.
If you notice redness, itching, or irritation, stop using the product.
Boba Capsule Creams
Clean a small area behind your ear or on your inner forearm or wrist.
Mix a small amount of the capsules with the gel cream, then apply it to the area.
Leave it on for 24 hours.
If you notice redness, itching, burning, or irritation, stop using the product.
Microneedle Serum
Clean a small area behind your ear or on your inner forearm or wrist.
Apply a small amount of the Microneedle Serum.
A mild tingling sensation is normal. Leave it on for 24 hours.
If the tingling becomes intense or you notice redness, swelling, or persistent irritation, stop using the product.
