the number of sessions really depends on what youre targeting and how your individual skin responds, which is why you see such a range mentioned by different people. for general skin rejuvenation or maintenance, three to four sessions spaced several weeks apart is often enough to see a noticeable improvement in tone and texture. for more significant concerns like moderate to severe acne scarring, providers often recommend a longer series, sometimes six or more sessions, because deeper textural changes need more cumulative collagen remodeling to really show up. some people also continue with occasional maintenance sessions every several months after completing their initial series just to sustain results over time, so what youre seeing online reflects genuinely different goals and starting points rather than inconsistent advice
