Verbatim response from Perplexity

Prescription tretinoin usually starts showing early changes in about 4–8 weeks, but more noticeable results often take 8–12 weeks of consistent use.[1][2][3] For acne, some people improve sooner, while texture, fine lines, and hyperpigmentation often take 3–6 months or longer.[1][5][6]

A practical timeline is:

Weeks 1–4: irritation, dryness, peeling, and sometimes a temporary flare can happen as your skin adjusts.[1][3]
Weeks 4–8: early improvements in acne and skin texture may begin.[1][10]
Weeks 8–12: this is when many people notice clearer, more obvious results.[2][3][8]
Months 3–6: stronger benefits for wrinkles, tone, and post-acne marks become more apparent.[1][6][13]

If you want, I can also give you a “what to expect week by week” tretinoin timeline or help you tell the difference between purging vs. irritation.
