When is It Safe to Wear Makeup After a Facial Mole Removal? (photo)

Typically you need to wait at least a week or until the skin is fully healed before applying makeup to a post surgical site.

It's difficult to tell from your photo, however, it looks like that quite a deep shave was done if it is still not healed in 3 weeks. Usually a "shave excision" should heal within a week to 10 days at the most. It is actually normal for a small scab to form after a shave which then falls off and it should heal much like a graze.

If shave excision is done correctly, it should not leave a scar (as the whole purpose of a shave excision is to avoid a scar which occurs with a formal excision).  Ideally, it forms a scab, which then falls off and a small pink patch remains which fades over time.

I usually let my patients wear makeup at 7 days (and the same if I do a formal excision as I remove the stitches at 7 days on the face).

It appears from your photos and history you have quite a deep shave and looks like a scab has formed in the bottom left hand corner photo. A scab is an inevitable response to a deep shave, it is not really something you can avoid. Whilst light powder or concealer is not dangerous over a scab, I would not pick at it or rub too much. Just let it fall off in its own time, and then commence massaging of the scar with moisturiser.
