This one thing made my retinoid tolerance so much better! 🏆

Retinoid burn? Not anymore. 👀 Ectoin-infused products made all the difference!

Here’s what I do:
👉 After cleansing at night, I apply the 120H Liquid Hydrator toner (ectoin!), then my retinoid, and lock it in with the All-in-1 Barrier Cream (also with ectoin!).
👉 The next day, I reapply both and stick to non-irritating actives, like peptides and pro-/prebiotics in the morning.

Ectoin + retinoids = less irritation, better results.
Have you tried this? Let’s chat👇

Thank you @4complexion for sharing this skin-saving hack ❤️
