What should be assessed before choosing a product?

Describe whether the change appears with expression or at rest, whether there is swelling and whether comfort or vision is affected. Mention previous injections and dry-eye symptoms. A product should follow a defined indication, not be selected simply because the area looks tired or another person had it. T1 F1 D1

Option	Main action or purpose	Question before treatment	Important limitation	Safety discussion
Botulinum toxin	Temporary reduction of selected muscle activity	Does the concern fit the product's indication?	Does not replace missing volume	Product-specific units and possible weakness T1 T2
Dermal filler	Material placed for a selected contour or volume target	What material, site and evidence apply?	Does not solve every dark circle or swelling	Vascular and inflammatory risks F1
No injection or separate assessment	Clarify surface, lid or other concerns	Would another evaluation answer the problem?	No automatic procedure recommendation	Avoid unnecessary treatment C1 B1

The table is a conceptual comparison, not an injection plan. Products, indications and country authorizations differ. A US label is evidence about that product and jurisdiction, not proof of Turkish authorization, clinic stock or interchangeability. This guide supplies no dose, injection point or conversion formula. T1 F1

How do the options and limits differ?

Options include no intervention, further assessment or one individually justified approach. If combination is proposed, ask why each component is needed and how effects will be reviewed. A combined package does not demonstrate better outcomes or lower risk. C1 T1 F1

Toxin does not remove excess eyelid skin, and filler does not correct every cause of an under-eye shadow. Effects and complications may differ in duration. A temporary intended effect does not mean every adverse effect is temporary or easily reversed. T1 F1

What information belongs in preparation?

Bring the exact names and dates of previous injections if known, medicines, allergies and relevant eye history. Mention swallowing, breathing or neuromuscular problems before toxin is considered. Ask about product identity and emergency contact arrangements; do not adjust medicines yourself. T1 F1 C2

Which risks should be compared?

Toxin can cause unwanted weakness, lid or brow droop and dry-eye symptoms; its boxed warning addresses spread of effect, including serious swallowing or breathing problems. Filler can cause bruising, swelling, infection or nodules; accidental vascular injection can cause tissue loss, blindness or stroke. These are different risk profiles, not interchangeable frequency estimates. T1 F1

What should follow-up document?

Record which product and site were treated, the intended goal and new symptoms. Review should distinguish a treatment effect from a complication before considering further injections. Ask when and how to contact the team; an automatic repeat date is not a substitute for reassessment. T2 F1 C2

What are the common questions?

Are toxin and filler interchangeable?

No. Their actions and indications differ. The same visible concern may need a different evaluation or no intervention at all. T1 F1

Can units be converted between toxin brands?

No. The referenced US product label states that its units are specific and not interchangeable with other toxin preparations. Do not compare doses as though brands were equivalent. T1

Is all filler easily reversible?

No. Materials differ and removal may be difficult or impossible. Even reducing a hyaluronic-acid filler requires medical assessment and carries risks; it is not a guarantee of complete reversal. F1

Does temporary mean harmless?

No. Temporary benefit does not exclude a serious or lasting complication. Ask about the actual product, site and alternatives rather than judging safety by duration alone. F1

Can I choose neither treatment?

Yes. You can seek information, postpone or decline. A decision should reflect your priorities and an understandable discussion of benefits, limits and risks. C1 C2
