Hello and thanks for your question. ResurFX is an excellent choice for skin rejuvenation for many patients due to its ability to treat a broad range of concerns. Because the device uses both intense pulsed light and non-ablative laser light to heat the inner dermal structure, it does leave the skin somewhat more vulnerable to UV exposure. However, the great aspect of this laser is that sunscreen and makeup can be applied the next day, so you can resume your normal activities and protect the skin right away. These treatments are done in our office all year round. As long as you can commit to excellent sun protection, these treatments are safe and effective. Also, if you have major events on the horizon, I would give yourself at least two weeks between your treatment and the occasion to ensure side effects have fully subsided.
