When red acne scars are treated with PDL, do the scars fade immediately, or continue to fade over the coming weeks?

When red acne scars are treated with a PDL, the appearance can sometimes temporarily darken.  It can take 6 weeks or so to see the results after the treatment.  

Vbeam laser is an excellent modality for patients who have rosacea, blushing of the skin, facial and body telangiectasia, spider veins, redness, post surgical redness, and skin flushing. It is a safe procedure that can be used at varying depths to help treat micro blood vessels in the skin. We also use it in our office for facial skin inflammation, keloids, and hypertrophic scarring. It is an important part of scar therapy. Vbeam can be combined with chemical peels and other lasers, but experience with the treatment is essential. The Vbeam laser does not affect deeper tissue. Schedule a consultation with an expert in Vbeam and you will find it to be an excellent modality for many skin types.

Treatments to reduce redness generally are most effective with a series.
To manage the good effects and lower any potential bad ones, it's sensible to prepare for a series of treatments.

Because there is continued pressure in the small veins, you shouldn't expect a single session to take care of the problem. You'll see improvement over time as you have the treatments.

One VERY important part of treatment decision is your genetic profile. Lasers work via heat and heat on skin with more pigment can be a problem if not carefully applied. See a board certified dermatologist who has multiple laser and light systems to choose from.
