# Read XO Injectables and the risks behind a change

A reading guide to cosmetic injectables. What changes, what can go wrong, and what you can leave alone.

You can be curious about a forehead line and still quite like it. There's no contradiction there. XO Injectables helps you understand a proposed change without turning your face into a list of things to fix.

## Two different changes

Toxins and fillers often get bundled together as “injectables.” They do different jobs. Keep that difference in mind when someone describes a change they could make to your face.

### Toxins work on movement

01

Botulinum toxin medicines [reduce how much certain muscles tighten](https://www.cdc.gov/botulism/prevention/botulinum-toxin-injections.html). That can make some expression lines less noticeable. The cosmetic effect is temporary.

Approval has limits, though. One medicine's label doesn't speak for every toxin or every use. The [FDA label for one cosmetic toxin](https://www.accessdata.fda.gov/drugsatfda_docs/label/2024/103000s5316s5319s5323s5326s5331lbl.pdf) sets out particular uses in adults, alongside risks such as eyelid or brow droop.

Ask which medicine is being proposed and what its label says about that use. “Just a little smoothing” leaves a lot unexplained. The [toxin chapter](/toxins) puts the approved uses and warnings together.

### Fillers work on fullness

02

Hyaluronic acid, often shortened to HA, is a sugar found in your body. As a filler gel, it [combines with water to add fullness](https://www.fda.gov/medical-devices/aesthetic-cosmetic-devices/fda-approved-dermal-fillers). It doesn't do the same job as a toxin.

Ask for the exact filler's name and patient information. [FDA approval covers particular fillers and uses](https://www.fda.gov/consumers/consumer-updates/dermal-filler-dos-and-donts-wrinkles-lips-and-more), not any gel anywhere on the face.

The serious risk is filler getting into a blood vessel. It can cause tissue death, blindness or stroke. The [filler chapter](/fillers) explains why that risk belongs beside any talk of fuller lips or cheeks.

## Bruising is only part of the story

Filler-related harm can be [permanent](https://www.fda.gov/consumers/consumer-updates/dermal-filler-dos-and-donts-wrinkles-lips-and-more). Toxin effects can [spread beyond the treated area and become life-threatening](https://www.accessdata.fda.gov/drugsatfda_docs/label/2024/103000s5316s5319s5323s5326s5331lbl.pdf). Those are things to hear plainly, while you're still deciding.

Product sourcing matters, too. FDA's 2024 counterfeit-toxin alert described incidents involving [licensed and unlicensed people](https://www.fda.gov/drugs/drug-alerts-and-statements/counterfeit-version-botox-found-multiple-states). A license check and a product check answer different questions.

Keep the [urgent warning signs](/risks#urgent-signs) handy. The same page explains [what happened with counterfeit products](/risks#counterfeit).

## Reassurance can come with details

Who would inject you? What training do they have? What exactly would they use? Those are fair questions, even if the conversation has been friendly so far.

For fillers, FDA tells providers to have [a plan for a blood-vessel complication](https://www.fda.gov/medical-devices/aesthetic-cosmetic-devices/dermal-fillers-soft-tissue-fillers). Ask who would act, where urgent care would happen and who answers after hours.

The [provider checks](/provider-checks) give you questions to take along. Getting answers doesn't commit you to a procedure.
