He/she meant well, but the implication from your point of view sure came out unfortunate. An awkward encounter. If you'd been honest and answered "No, I'm just wearing more makeup now" they probably would have felt awful or awkward/embarrassed. But it's not necessary to and the awkwardness of the situation was incidental, so maybe it's better to spare their feelings. Or maybe it's better not to keep it to yourself and not to protect them from the truth. I guess it's debatable, or just up to one's personality/preference.
