FAQ

What skin types is Calming Barrier Serum best for?

All skin types can benefit from the soothing, hydrating benefits of our Calming Barrier Serum, especially those with stressed or reactive skin. It's also clinically proven to be noncomedogenic and hypoallergenic, making it a great pick for acne-prone and sensitive skin.

My skin is very dry. Should I apply a lot at once?

We recommend sticking to a small amount at a time for better absorption. Wait 60 seconds to let absorb, then add more layers for additional hydration if desired. All skin types (especially dry) should apply on slightly damp skin for the best hydrating effect.

What other skincare products should I use with Calming Barrier Serum?

If you're need of some extra calm, our Centella Asiatica Calming Mask is perfect for an added boost of soothing care.

Can I use Calming Barrier Serum both day and night?

Yes! Use Calming Barrier Serum in both your morning and evening skincare routines.

How has the new Calming Barrier Serum formula changed from the original version?

To make Calming Barrier Serum even better, we kept its soothing, hydrating feel while upgrading the formula with our exclusive Green Tea-HA™ and moisture-locking panthenol.

What is Green Tea-HA™?

Far beyond a simple mix of green tea and hyaluronic acid, this BOJ-exclusive ingredient is the secret to preserving the antioxidant benefits of green tea leaves, known for their natural soothing, anti-inflammatory, and redness-relieving properties. We extract those active compounds using the natural water-binding properties of hyaluronic acid to gently draw out green tea extracts. (Think of it like a sponge soaking up all the nutrients your skin loves.) The final step is encapsulating everything into tiny liposomes that absorb better and feel less sticky than traditional hyaluronic acid.
