what are neurotoxins?
neurotoxins are injectable treatments that temporarily relax targeted facial muscles responsible for expression lines. by softening muscle activity, the skin appears smoother, more rested, and balanced — while preserving natural facial movement.
at darlum skin, neuromodulators are used with a conservative, anatomy-based approach to enhance facial harmony rather than freeze expression.
what concerns can be treated?
neurotoxins may help improve the appearance of:
-
frown lines (11s) between the eyebrows
-
forehead lines
-
crow’s feet around the eyes
-
bunny lines on the nose
-
lip flip (upper lip relaxation)
-
gummy smile
-
chin dimpling
-
masseter hypertrophy (jaw slimming / clenching)
-
excessive sweating (hyperhidrosis)*
*treatment areas depend on individual anatomy and medical evaluation.
who is a good candidate
neurotoxins may be a good option if you:
-
notice dynamic lines that appear with facial movement
-
want a refreshed, well-rested appearance
-
prefer non-surgical treatments with minimal downtime
-
are seeking subtle, natural-looking results
-
are interested in preventative aging treatments
a personalized consultation and medical history review are required to determine suitability.
who may not be suitable
neurotoxins may not be recommended if you:
-
are pregnant or breastfeeding
-
have a known allergy to botulinum toxin products
-
have certain neuromuscular disorders (e.g. myasthenia gravis, als)
-
have an active infection or inflammation at the treatment site
-
are experiencing uncontrolled medical conditions
what to expect
treatment time: 10–20 minutes
downtime: minimal
results begin: 3–7 days
full effect: 10–14 days
duration: approximately 3–4 months (varies by product and individual metabolism)
results are temporary and maintenance treatments are recommended.
differences between botox®, dysport®, and xeomin®
while all three neurotoxins are derived from botulinum toxin type a, they differ slightly in formulation, diffusion, and onset. the appropriate product is selected based on facial anatomy, treatment area, and individual response.
​​
​
​
botox®
botox® is the most widely used and well-studied neurotoxin. it offers precise, predictable results and is often chosen for targeted areas requiring controlled muscle relaxation.
commonly used for:
-
forehead lines
-
frown lines (11s)
-
crow’s feet
​
onset: 3–7 days
duration: ~3–4 months
dysport®
​
dysport® has a slightly broader diffusion pattern and may begin working a bit faster for some patients. it is often selected for larger treatment areas.
commonly used for:
-
forehead lines
-
frown lines
-
masseter (jaw slimming)
onset: 2–5 days
duration: ~3–4 months
xeomin®
xeomin® is a “naked” neurotoxin, meaning it contains no accessory proteins. this makes it a preferred option for patients who may be concerned about resistance or sensitivity.
commonly used for:
-
frown lines
-
patients with prior exposure to other neurotoxins
-
individuals seeking a more purified formulation
​
onset: 3–7 days
duration: ~3–4 months
how we choose the right product
product selection at darlum skin is based on:
-
facial anatomy and muscle strength
-
treatment goals
-
prior response to neuromodulators
-
desired onset and diffusion
during your consultation, the most appropriate option will be recommended to achieve balanced, natural-looking results.
aftercare guidelines
-
remain upright for 4 hours
-
avoid rubbing or massaging treated areas for 24 hours
-
avoid strenuous exercise for 24 hours
-
avoid facials, saunas, or excessive heat for 24–48 hours
detailed aftercare instructions are provided at your appointment.
our approach
at darlum skin, treatments are guided by:
-
facial anatomy and balance
-
conservative dosing
-
individual muscle function
-
long-term skin and facial health
the goal is refinement — not overcorrection.
