Lips or Forehead: Which Should I Preview First?
LipsUp previews one area per scan: lips or forehead, never both at once. If you're not sure which to try first, here's a practical way to decide, and a reminder that it isn't permanent.
Opening LipsUp for the first time means choosing one area to preview: lips or forehead, not both in the same scan. That single-select step trips people up more than it should, because it feels like a bigger commitment than it is. It isn't. Whichever area you pick first, you can run a separate scan for the other one any time afterward, on the same selfie or a new one, and the first scan has no effect on the second.
Why the app only shows one area per scan
The scan flow uses on-device face detection to crop just the area you select, lips or forehead, before anything is sent for processing. Only that crop leaves your device; the rest of the photo, and your full face, stay on your phone. That's the actual reason the app works one area at a time instead of offering a combined preview: it's built to process the smallest piece of the photo it needs for the area you chose, not the whole face at once. Each scan produces a single result, shown as a before/after on your own selfie. There is no option to generate both areas from one tap, by design.
The app's own framing for this is "see your new look before you decide" - fuller lips and a smoother forehead, both on your own selfie, just not in the same frame. One scan, one area, one before/after to look at. That's the entire mechanic, and it's worth understanding before you worry about which to pick, because it means neither choice is heavier than the other.
So which one do I scan first?
There's no universal right answer, and the order doesn't change anything about either result. Three questions tend to settle it quickly for most people:
- Which one do you actually notice in the mirror? Not the thing a filter flagged or a friend mentioned once, but whichever one you catch yourself looking at without meaning to. That's a stronger signal than any general idea of "what people usually do first."
- Which change are you more curious about? Curiosity is reason enough on its own. If you keep wondering what fuller lips would look like on your own face, or what your forehead would look like without the lines that show up mid-conversation or mid-photo, that pull is worth following before anything else.
- Which one changes more for you day to day? Lips show up in every photo, every video call, every mirror check. A forehead line might only register in certain light or certain expressions, like raised eyebrows in a photo. Neither pattern is more valid than the other, but noticing which one describes you narrows the choice fast.
In practice, the answer often falls out of something specific rather than a general preference. Someone with an event coming up might scan lips first simply because that's the feature they'll be thinking about getting ready that week. Someone who keeps noticing a line in close-up photos or video calls might scan their forehead first for the same reason, it's the thing currently on their mind, not a ranking of which area "matters more." Both are equally good reasons to start somewhere.
If you've weighed all three and you're still torn, pick either one. Genuinely, it doesn't matter which comes first - what matters is that you get a concrete picture instead of guessing.
It isn't a one-time decision
This is worth repeating, because the single-select screen can make it feel more final than it is: your first scan doesn't lock you into anything. Scan your lips today, and if you find yourself curious about your forehead next week, or next month, run a second scan for that, same app, same simple flow. Nothing about the first choice limits, changes, or uses up the second. Each scan is its own result on its own crop of your photo, independent of whatever you scanned before it.
If you'd rather think about both areas together from the start instead of picking one first, "Lip Filler and Forehead Botox: How to Think About Doing Both" covers how people typically sequence both changes over time. This article is only about which single preview to run first; that one is about what comes after you've tried both.
What the preview actually shows you
Whichever area you scan, you're looking at a computer-generated visualization on your own selfie, a before/after built to give you a concrete picture, not a prediction of how a real procedure would turn out on your face. For lips specifically, "What Will Lip Filler Actually Look Like on Me?" goes into how that preview relates, and doesn't relate, to an in-office result. For forehead lines, "Why You're Getting Forehead Wrinkles" explains what's actually happening on your skin before you preview anything on it.
Consult a licensed professional before any cosmetic treatment. A preview is a starting point for a conversation with one, not a substitute for it.
QUESTIONS
Frequently asked
Can I preview both lips and forehead in the same scan?
No. LipsUp previews one area per scan, lips or forehead, so each scan crops and processes just the area you select. If you want to see both, run two separate scans, one for each area.
Does scanning one area first affect the other scan later?
No. Each scan is independent. Choosing lips first doesn't change or limit what you'll see if you scan your forehead afterward, and there's no requirement to do both or to do them in any particular order.
How do I decide which area to scan first?
Think about which one you actually notice day to day, which change you're more curious about, and which bothers you more in the mirror. There's no wrong answer, and you can always run the other scan afterward.
