Why it matters

Skin and stress have a direct neurobiological connection. Stress triggers cortisol and neuropeptide release, which activates mast cells in the skin, increases sebum production, disrupts the skin barrier, and triggers inflammatory responses. Breakouts, redness, dryness, eczema flares, and psoriasis can all be directly triggered or worsened by stress. The delay between the stress event and the skin response — usually two to five days — makes the connection almost impossible to identify without tracking both over time.

When Normal helps

Normal tracks your stress levels alongside your skin condition over time, accounting for the typical delay between stress and skin response. It finds your personal stress-skin pattern — how long the delay is, how severe the response is, and whether certain types of stress are more likely to trigger skin reactions than others.

How Normal finds it

Tell Normal about your stress and your skin every day. Over four to six weeks it finds the specific relationship between your stress patterns and your skin reactions, including the lag time that makes it hard to see the connection without data.
