Why this comparison does not rank the two
Most pages that compare two lasers are built to move a reader toward one of them, and the layout usually says so before the text does. That structure cannot be trusted by someone who is genuinely deciding, because it has already decided. This site compares two ablative lasers as two depths of deliberate injury. Both columns carry the same weight, and neither is described as the safe choice or as the one that gives the better result.
How the balance is kept
Each option has a guide that is candid about what it costs. The deeper option's guide names the week and more of raw healing, the weeks of redness, the higher pigment risk and the fact that it commits to a depth in one step; the shallower option's guide names the series it is usually delivered in, the under-treatment risk that comes with choosing too conservative a depth, and the fact that it still carries pigment risk on darker skin. One guide is given to darker skin, where both options carry more risk, and one to the cases where both should be declined.
How it is reviewed
Content is medically reviewed by Ke He, MD, head of skin and laser aesthetics at Chongqing West District Hospital, and the review date appears on every article. The site names no device brand and no product, quotes no wavelength, no energy setting and no price, guarantees no outcome, and states plainly that healing is measured in weeks and that pigment can change in either direction.
What no website can do
It cannot measure the depth of your wrinkles, tell you how your skin will heal, or judge how much recovery your life can absorb. Those answers come from an examination and from a conversation about your calendar, and the two lasers are chosen from both. Read this site to arrive at that appointment able to ask better questions, not to arrive at a decision without it.
