Thanks so much for your question and I can appreciate your concern. With appropriate settings, Halo should only remove unhealthy pigment such as that you have developed from sun exposure. It should not change your natural coloration or leave you white. I have used Halo for several years and in many patients with darker skin and have never had a patient turn white or very pale with it. Halo is actually one of the better lasers for olive skin.That being said, any lasers need to be used with more caution in darker skin types, particularly if you have quite dark olive skin. Make sure that your physician has experience with both your skin type and the Halo laser to determine the best settings for your goals.
