What Are Laser Skin Treatments?
Skincare lasers deliver focused light at a specific wavelength, measured in nanometers (nm).
Different wavelengths are absorbed by different targets in the skin, including water, pigment, and blood. That absorbed energy creates a controlled response. Depending on the device, it may help improve the appearance of fine lines, wrinkles, uneven texture, visible pores, uneven tone, etc.
Wavelength itself doesn’t tell the whole story. This guide breaks down the details so you can understand the science, compare the technologies, and choose your treatment with confidence.
