This is a pretty broad definition, so we asked her to really break it down for us. She says people with sensitive skin will have some or all of these skin concerns:

Texture: "Delicate skin may be thinner than average skin types."

Tightness: "Sensitive skin tends to be tighter, which indicates dehydration."

Redness/blotches: "Sensitive skin tends to be red or blotchy because the capillary action (the ability of a liquid to flow to the skin) may be over-reactive.

Flakiness/cracking: "Coincides with dehydrated skin."

Small rash-like bumps: "Not to be confused with breakouts."
