How to Choose the Right Option for Your Skin
- Identify your primary concern: Choose hydrating serums with snail mucin if skin feels dry or dull, or opt for peptide and collagen-boosting serums for firmer, more elastic skin.
- Consider skin type: Lightweight essences and serums suit oily or combination skin, whereas nourishing creams and dual essences work well for sensitive or dry skin.
- Layer thoughtfully: Use watery serums like the 6X Peptide Collagen Booster as a first step after cleansing, then follow with richer essences or creams for best absorption and effect.
- Start slow with active ingredients: For serums with niacinamide or peptides, patch test first and introduce gradually to avoid irritation.
- Opt for sets or masks for trial: Travel kits and sheet masks offer a gentle way to experience snail mucin benefits before committing to full-size products.
