How long does collagen biostimulator injection take to work for nasolabial folds?

The initial fullness is not the same as the intended collagen response and can reduce as swelling settles. Improvement depends on the product, treatment areas, skin characteristics, and whether a planned series is needed. Nasolabial folds may soften rather than disappear, and the final appearance should be judged after the treated tissue has settled.

Follow the injector's instructions about massage, skincare, exercise, heat, and makeup. Avoid pressing or manipulating the area unless specifically advised. Attend the review even if the first result looks uneven, because swelling can obscure the developing effect and the clinician may decide whether another session is appropriate.

Seek prompt advice for increasing pain, spreading redness, warmth, pus, marked asymmetry, skin colour change, or a firm lump that does not settle. Emergency help is needed for vision changes, severe headache, weakness, or trouble breathing after an injection.

Ask which product is planned, when its result should be assessed, whether more than one session may be considered, how to manage swelling, and which changes require immediate contact.
