What Counts as Skin Rejuvenation, and What It Can Realistically Change
A handful of different tools do this work, using fine needles, light, or a measured acid solution to reach the skin in different ways. What they have in common is depth. Each one makes a small, deliberate change under the surface, and your body responds by rebuilding that area with more collagen and a smoother texture. A serum cannot reach that layer. It sits on top of your skin until you wash it off, which is fine for maintenance but doesn’t address scarring or real texture issues.
