Ingredient comparison
Centella and snail mucin are both popular K-beauty ingredients, but they do not play the same role. Centella is usually chosen for calming support, while snail mucin is usually chosen for hydration, comfort and smoother-looking texture.
Quick decision
If your skin looks red, reactive or irritated, start with Centella. If your skin feels dehydrated, rough or tight, snail mucin may be a better hydration layer. If your skin is both sensitive and dehydrated, the two can work well together.
Choose Centella: redness, reactivity, irritation, sensitive-looking skin.
