To undo a reaction on Facebook, click your current reaction on a computer, or tap it in the app on Android or iPhone. To swap it instead, hover over it on a computer or tap and hold on a phone. Facebook says you can only leave one reaction per post or comment.
We've all done it. You scroll quickly, your thumb lands on the wrong icon and suddenly you've sent an angry face to a friend's holiday photo, or a laughing face to something sad. It's a small slip, but it can feel like a big one, especially if the post belongs to a client, a customer or someone you're trying to impress.
The good news is that Facebook lets you take a reaction back, and the help centre keeps the steps short. Below are the exact moves for a computer and for the Facebook app on Android and iPhone, plus a few things worth knowing about how reactions behave.
Undoing a reaction on Facebook from a computer
Facebook's help centre says that to remove your reaction to a post or comment on a computer, you click your current reaction. That's the whole job:
- Find the post or comment you reacted to.
- Look for your current reaction next to Comment and Share. It'll show as the icon you picked, such as Love or Haha, rather than a plain Like.
- Click that reaction once. It's removed.
One click is all you need. If you click again straight afterwards, you'll just be reacting again, so give the screen a second to update before you try anything else.
Undoing a reaction in the Facebook app on Android and iPhone
On a phone, the help centre gives the same short answer: tap your current reaction. The steps are the same on Android and iPhone.
- Scroll to the post or comment where you left the reaction.
- Find your current reaction next to Comment and Share.
- Tap it once to remove it.
The tricky part on a phone is that a long press does something different. If you tap and hold, you open the choice of reactions rather than removing yours. Keep to a quick tap when you want to undo.
Swapping your Facebook reaction instead of removing it
Sometimes you don't want to take the reaction away, you just chose the wrong one. Facebook's help pages cover that too.
- On a computer, hover over your current reaction (next to Comment and Share) and select a new one.
- On Android and iPhone, tap and hold your current reaction, then select a new one.
That's a neater fix than removing and starting again, and it's worth using whenever the problem is the type of reaction rather than the fact you reacted at all.
How reactions work on Facebook, according to the help centre
It helps to know the ground rules. Facebook's help pages explain that liking tells your friends you enjoyed their post or comment, while reacting lets you specify your response. They also say you can only leave one reaction per post or comment.
That has a practical upside. You can't stack reactions by accident, so when you open a post and see one icon beside your name, that's the only one you've left. On a computer, reacting means hovering over Like and choosing a reaction, and the most popular reactions appear below the post or comment as small icons.
| What you want to do | Computer | Facebook app on Android or iPhone |
|---|---|---|
| Remove your reaction | Click your current reaction | Tap your current reaction |
| Change your reaction | Hover over your current reaction, then pick a new one | Tap and hold your current reaction, then pick a new one |
Menus vary by app version, so if a gesture feels different on your device, look for the same reaction icon beside Comment and Share.
Finding the reactions you've left through your Facebook activity log
What if you can't remember where you reacted? Facebook's help pages say your activity log has an Interactions category for reviewing things such as likes, reactions and comments. That makes it the place to go if you've reacted late at night and want to check what you did.

- On a computer, click your profile picture in the top right of Facebook.
- Select Settings and privacy, then click Activity log.
- Look for the Interactions category and open it to review your reactions.
On Android, tap Menu in the top left, tap your name, tap Options below your profile picture, then tap Activity log. Only you can see your activity log. Facebook adds that the posts and other content in it may appear in other places on Facebook, such as your timeline, search or friends' Feeds. If you're curious about what else is in there, I've covered finding archived Facebook posts and whether Facebook has a watch history, which both start from the same log.
If you can't undo a Facebook reaction
- Tap the right thing. You need to tap or click the reaction that's currently showing, not the Comment or Share buttons beside it.
- Use a quick tap on the phone. A long press opens the picker, so tap once to remove.
- Try the computer. If the app seems stuck, the website is a simple way to check whether the reaction is still there.
- Update the app. Menus vary by app version and an older one can behave differently.
- Reload the page. Sometimes the screen simply hasn't refreshed after you removed it.
The help page doesn't say whether the other person is told when you remove a reaction, so I won't promise either way. The safest approach is to fix it quickly and not worry too much.
When a Facebook reaction matters for your business or brand
For most people, a mistaken reaction is a passing embarrassment. If you run a small business or build an audience, though, it can matter more. A cheerful reaction on a customer's complaint or a laughing face on a sad announcement can look careless. Get into the habit of checking what you've reacted to before you close the app, and undo anything that sends the wrong message.
If a reaction is part of a bigger problem, such as a post that upset you or a person who's bothering you, undoing the reaction won't fix that. Report the post to Facebook, and if you're ever in danger, contact the police.
