Popular Noninvasive Cosmetic Treatments
Popular treatments feel safe because many people have had them, so it helps to separate how common a treatment is from how it should be treated if something goes wrong.
For safety, start with a dermatology academy's safety page for cosmetic treatments. This page then reads a plastic surgery society's popularity ranking and says where a clinician takes over.
Which treatments lead the ranking
The American Society of Plastic Surgeons says the top three noninvasive procedures according to ASPS include botulinum toxin type A, fillers and chemical peels. A ranking like this counts procedures. It does not rate how well any of them suits you.

The full ranking, with the society's own framing, is in a plastic surgeons' society blog on the most popular noninvasive treatments.
Popular and urgent are different questions
This desk sorts questions into cosmetic and urgent. Asking which treatment is most common, or which one to try first, is cosmetic and can wait for a consultation.
Something that appears on your skin after any of these treatments is not a popularity question. It goes to the clinician who treated you.
How to read a ranking
Check who published it, what it counts and what year it covers. Then keep the ranking in its place, as a description of demand and not an endorsement.
Rye readers comparing options can bring the three names above to a consultation and ask how each fits their own skin.
Where guidance can differ
The ranking here comes from one society. A different body may group or name treatments differently, and the difference tells you about the body as much as the treatments.
Where a clinician takes over
Choosing among popular treatments is a conversation with a clinician, and a reaction after treatment is theirs to assess.
To see how the society places these treatments within the wider field, read the society's page on skin rejuvenation and resurfacing before you book.
