Concise answer
Injectable treatments have recognised benefits and risks; they are not risk-free. Safety depends on medical suitability, product authenticity, anatomy knowledge, sterile technique, conservative planning and access to complication care.
The appropriate product and amount cannot be chosen from a trend, photograph or price list alone.
Consent should cover expected effects, limitations, alternatives, aftercare and warning signs that require urgent contact.
When evaluation may help
A qualified in-person consultation is essential before treatment; urgent review is needed for severe pain, skin colour change or visual symptoms afterward.
