Dual Yellow Laser is a highly safe procedure that gently treats acne and fine lines, without the need for topical anesthesia. During the treatment, patients will feel a minor tingling sensation from the laser beam. After the treatment, there may be a warm sensation and skin redness, which will naturally disappear. In general, dark spots, red marks, and capillaries will be completely removed if an appropriate amount of laser energy is applied. However, acne scars and stretch marks may require continuous treatment to obtain optimal results.
