5 Injection Mistakes New Providers Make

What's inside

Five mistakes. One guide. No fluff.

01

Injecting without a complete facial assessment

Why treating "the feature" instead of "the face" produces technically fine results that look off.

02

Under-respecting vascular anatomy

The difference between a bruise and a vision-threatening complication is anatomical knowledge plus a two-minute response window.

03

Over-injecting on the first visit

More product is not better technique. Why under-correction beats over-correction, every time.

04

Neglecting injection depth and tissue plane

The same product, in the same spot, at the wrong depth, produces a different outcome entirely.

05

Underestimating the consultation

The consultation isn't the step before treatment. It's half the treatment.

Practicing medical aesthetics since 2009. Edwin built The Medwin Method after years of developing his own injection technique and aesthetic judgment โ€” and noticing that most training programs hand new providers slides, not supervised reps. This guide is the pattern recognition from those 15 years, compressed into something you can act on immediately.
