Tips to Hide a Cold Sore:
- Use a concealer with a creamy texture, not a liquid. These concealers are usually sold in small jars, tubes, or compacts, and are very concentrated.
- Only a small amount of a heavy concealer is needed — a little goes a very long way.
- If you have a lot of redness, you may benefit from using concealer in two different shades: a yellow-based concealer to neutralize redness and a concealer that matches your skin tone.
- Dab on the yellow concealer using a disposable makeup sponge. Start with a very small amount and build it up, if necessary, to avoid cakiness.
- After the yellow concealer is applied, top it with a very light dusting of finishing powder. Pat it on lightly to avoid disturbing the concealer.
- Next, gently dab on the concealer color that matches your skin tone and use a stipple motion to blend.
- Apply another light dusting of finishing powder to set.

Bonus tip from Cosmopolitan.com:
"I would advise using disposable applicators to minimize the risk of spreading the virus. Small makeup sponges will help achieve a better finish than cotton buds as the scab, plus moisture on the skin can encourage little bits of cotton to stick."
