- Primary Ingredient:Snail Mucin
- Bottle Size:3.38 oz
- Key Benefits:Repair and glow

It is surprisingly generous in volume, which is great for applying to both the face and body. Because it contains active ingredients, you should start by using it only a few times a week to make sure your skin tolerates the potency.

Frequently Asked Questions
Do I really need a serum if I already use a moisturizer?
Think of your moisturizer as a heavy winter coat and your serum as a thermal base layer. A serum delivers a concentrated dose of active ingredients deep into the skin that a standard cream might not reach. Using both creates a multi-layered approach to hydration that keeps your face soft all day long.
When is the best time to apply a hydrating serum?
Apply your serum to slightly damp skin immediately after cleansing. The water on your skin helps the humectants draw more moisture into your cells. Follow up with a moisturizer within sixty seconds to seal everything in before the water evaporates.
Can I use a hydrating serum if I have oily skin?
Absolutely. Oily skin often produces excess sebum because it is actually dehydrated and trying to compensate. A non-comedogenic serum provides the water your skin craves without clogging your pores or adding extra grease.
How much product should I use per application?
You only need a pea-sized amount for your entire face and neck. Using too much product can lead to stickiness and waste your money. If the serum is high quality, that small amount should provide ample coverage and hydration for your skin.
Should I see results immediately?
You will notice an instant plumping effect because the humectants pull water into the top layer of your skin. However, deep hydration and barrier repair usually require four to six weeks of consistent daily use. Patience is the secret ingredient to long-term skin health.
