- Application instructions
- Safety warnings
- Expected results
- Any mention of stem cell-related ingredients or smoothing technology

What I Checked for Safety
Safety mattered to me just as much as results. I made sure to look for:
- Patch test advice
- Clear usage directions
- Suitable storage instructions
- Any ingredients I might be sensitive to
If a product doesn’t give clear guidance, I usually hesitate before buying.
