Ephelides are a genetically determined sun response — melanin production without an increase in melanocyte number. They darken with exposure and fade without it.
Existing melanocytes produce more pigment in response to ultraviolet light. The cell count is normal, which is why freckles behave differently from lentigines and why they recur with exposure.
Freckles fade in winter and return in summer. Solar lentigines do not fade. That single observation separates them, and it changes what treatment can realistically promise.
Distribution, whether the pattern is longstanding since childhood, seasonal variation, Fitzpatrick type and family history.
Pigment-selective treatment reduces visible pigment, but because the underlying response is genetic, recurrence with sun exposure is expected rather than a failure. Photoprotection is the durable part.
Anyone seeking permanent removal is told plainly that the response is genetic and returns with exposure.
