Why exfoliating lips too aggressively can leave them more vulnerable, not just smoother

Why lip skin has less margin for exfoliation error than facial skin does

Lip skin's already-thin structure means it has considerably less buffer before exfoliation crosses from beneficial surface-smoothing into actually thinning and stressing the skin further — a frequency or intensity that would be entirely safe on facial skin can be genuinely excessive for the more delicate, thinner lip surface.

What over-exfoliated lips actually look and feel like, distinct from simply dry lips

Over-exfoliated lips can present as persistently sensitive, prone to stinging when anything (food, drink temperature, lip products) touches them, and paradoxically still rough-feeling despite frequent scrubbing — a state distinct from simple dryness, where the skin's own protective surface has been mechanically compromised by excessive exfoliation rather than just lacking moisture.

Limiting lip scrub frequency appropriately given the area's thinner, more delicate structure

Limit lip exfoliation to once or twice weekly at most, using genuinely gentle pressure given the area's thinness, and watch for signs of over-exfoliation (persistent sensitivity, stinging) as a signal to reduce frequency further — lip skin's margin for exfoliation error is narrower than facial skin's, calling for a correspondingly more conservative approach to frequency.
