LookPrep vs Crisalix for lips

Swipe the table sideways to see both columns.

Crisalix does something LookPrep does not attempt: it reconstructs a three-dimensional model of you. Three ordinary photos, no scanner, and it has a mesh it can deform in volume — so the result turns. You can check the profile and the three-quarter, and Crisalix carries that into virtual and augmented reality. A photo-based preview shows one viewpoint, and one viewpoint is genuinely less information.

The breadth is not close either. Its face simulator has six sections — Cheeks, Chin, Injectables, Facelift, Lips and Nose — and injectables run across 21 zones, from forehead lines to jawline and chin. Beyond the face it simulates breast augmentation, reduction, lift and reconstruction, plus abdominoplasty, liposuction and buttock procedures. If your question is bigger than your lips, Crisalix has an answer and LookPrep has none.

The professional terms require a licensed physician or aesthetic professional. Crisalix supports both in-person and remote consultations, so a professional account is not proof of a physical examination. The practice tools include patient records, videoconferencing, booking and a patient app; surveys and branding are documented too. Availability depends on the plan and the clinic's configuration.

• A rotatable 3D model from three ordinary photos, with no scanner hardware.
• Face, breast and body, surgical and non-surgical, where LookPrep is lips only.
• 21 injectable zones, so lips can be judged against the face around them.
• Professional accounts limited to licensed physicians and aesthetic professionals.
• A vendor-reported study covering 4,517 doctors and 229,911 consultations in 111 countries during 2014–2025.

LookPrep answers one question and stops: which named lip look interests you, and which preview settings would you like to discuss with a provider. It is built for the weeks before you book anything — the evenings spent scrolling saved photos, working out whether the thing you keep liking is Russian lips or a cupid's bow that has simply been defined.

That is why the vocabulary is different. LookPrep works in the units the invoice is written in: Juvéderm Volbella XC at 0.55, 1.0, 1.5 or 2.0 mL, Restylane Kysse from 0.5 to 2.0 mL, RHA Redensity from 0.3 to 2.8 mL. Product families are reference points, never recommendations — LookPrep is independent of Allergan, Galderma, Revance and Prollenium.

The lip flip is kept separate for the same reason: 4 or 6 units rather than millilitres, for subtle upper-lip eversion without added filler volume. Each look also carries a standardization grade, and four — cherry, keyhole, heart-shaped and butterfly — are graded contested and deliberately not shown as a definite outcome. Publishing which of your own looks are shaky is the honest version of a shape menu.

• Lips and lip flip only, on the web, with no app to install.
• Amounts in mL per product family, and 4 or 6 units for a lip flip.
• Eight named looks with published standardization grades, four marked contested.
• 8 previews for $19 or 20 for $29. No subscription.
• An 18-plus gate and a recorded photo consent before any render; uploaded faces are not used to train LookPrep models.

Crisalix is reachable directly by patients. Its homepage invites people to upload three photos and advertises free 3D viewing. The linked public signup page reviewed on 6 October 2026 showed a starting price of GBP 24. Check the signup flow for the access and price offered to you; this review did not complete a purchase.

Both therefore offer a direct patient route. Crisalix also markets a broader journey before, during and after consultation, with practice tools for booking, video visits and patient communication. The clearer distinction is scope: face, breast and body modelling with Crisalix, or LookPrep's focused lip comparison before a consultation.

Crisalix's injectables guide documents percentage sliders across 21 zones. That guide and the lip guide reviewed do not specify filler millilitres or syringe counts. The lip guide lists Cherry, Flower, Heart, Natural, Rounded and Russian, with volume, height, width, contour and hydration controls. LookPrep is therefore not the only product here that names lip shapes.

LookPrep names eight looks and keeps going into product family and millilitres. Russian, cupid's bow definition and natural enhancement are graded well-defined; cherry, keyhole, heart-shaped and butterfly are graded contested; doll lips is flagged as a marketing label. They are technique-and-placement labels approximated by a treatment and an amount. Neither tool decides anything: LookPrep does not assess candidacy, prescribe a product or recommend a dose.

Crisalix's patient terms state that its 3D images "are for visualization and illustrative purposes only, and are not a substitute for a consultation with a qualified physician", and that final results "may vary significantly". Its community page repeats the point.

LookPrep also describes its previews as planning visuals. Neither tool predicts your medical result or replaces an assessment by a qualified injector.
