But what exactly are they, and what can they do for you? 

What is Snail Mucin?

Snail mucin can sound a little intimidating in the beginning. But in K-Beauty, it’s one of the most beloved ingredients. It’s known for its intense hydration and its ability to plump and smooth the skin. It also features wound-healing properties, making it helpful for those with acne scars and damaged skin barriers. On top of that, it calms redness and irritation. This leaves your complexion more balanced and resilient.

What is Niacinamide? 

Niacinamide might be something you are more familiar with compared to snail mucin. Niacinamide works for almost every skin type. It brightens dull complexion, fades hyperpigmentation and post-acne marks, and strengthens the skin barrier.
