### ⭐⭐⭐⭐⭐ Lovely Serum!

### ⭐⭐⭐⭐⭐ My Go-To Serum for Barrier Support

### ⭐⭐⭐⭐ Great product very hydrating, poor packaging
*by M***D on 7 September 2025*

This product is great as a second serum step in your routine. I used it to replace my moisturiser as felt it was thick enough to seal and hydrate the skin. It also seems to help with my redness and rosacea. The product itself is promising leaving my skin soft hydrated and sealed however the pump is poor. I also found this product helped some barrier issues I had on my elbows so used it as a healing balm. Its thick but not greasy it has a gloopy serum gel like texture so would work well for oily skin.
