Skin1004 Centella Ampoule (100ml from $15 on eBay)
Infused with 100% Centella Asiatica, this ampoule is supposed to moisturise, soothe, and strengthen the skin barrier. I don't see much of a soothing effect (which is strange), but it does moisturise (and hopefully strengthens my skin barrier). The price is great since it is 100ml, but I am a bit unsure of the exact effect
