Hey Reader!

​

With more sweat, SPF, and outdoor grime, it’s tempting to reach for strong cleansers or exfoliate more. But that can damage your moisture barrier, leading to irritation and breakouts.

Science says: Over-cleansing can strip essential lipids and disturb your skin’s microbiome—both crucial for healthy, resilient skin.

Your new cleanse routine:​
✔️ Switch to a gentle, sulfate-free cleanser (gel or foam is fine—just avoid drying alcohols)
✔️ Consider double cleansing at night if you wear makeup or water-resistant SPF
✔️ Don’t exfoliate more than 2–3x/week, and always follow with hydration

🧖‍♀️ Audit your cleanser shelf this week—your skin barrier will thank you.
