d'alba Piedmont Revitalizing Double-Layer Serum 1.01 fl.oz — 100hr Hydration & Hyaluronic Acid

d'alba Piedmont Italian White Truffle Double Layer Revitalizing Serum is a dual-phase facial serum that delivers up to 100 hours of hydration while promoting firmer, smoother-looking skin.

This serum combines a water-based and oil-based layer infused with Italian white truffle extract, hyaluronic acid, and centella asiatica to lock in moisture and improve skin texture. Formulated in the Korean skincare tradition, it uses a double-layer delivery to target dry, dull, and uneven skin by supporting hydration retention and surface resilience without heavy residue.

How does the double-layer formula work for lasting moisture?

The serum separates into two phases: a hydrating aqueous layer and a nutritive oil layer. When shaken and applied, the layers blend to deliver both immediate water-binding benefits and longer-term moisture sealing for sustained hydration.

• Shake to emulsify both phases for an even application
• Hyaluronic acid attracts and holds water in the skin
• Oil phase helps reduce transepidermal water loss
• Luxury truffle extract supports skin luminosity

Will this serum help with firmness and texture?

While not a clinical treatment, the serum contains ingredients chosen to improve the look of elasticity and surface smoothness with regular use. Centella asiatica and hyaluronic acid work together to hydrate, plump fine lines, and create a softer-looking complexion over time.

• Centella asiatica supports a more resilient skin feel
• Hyaluronic acid plumps to reduce the appearance of fine lines
• Lightweight oil provides suppleness without heaviness
• Consistent use enhances overall skin texture

How should I use it in my skincare routine?

Use this serum after cleansing and toning, morning and night, shaking well to combine the layers before dispensing. Apply a few drops to the face and neck, then follow with moisturizer and SPF in the morning to lock in results.

• Shake bottle for 5–10 seconds before use
• Apply 2–4 drops to damp skin for best absorption
• Layer under moisturizer and morning SPF
• Suitable as part of both AM and PM routines

Is this suitable for sensitive or oily skin types?

The formula balances a hydrating water phase with a lightweight oil phase to suit multiple skin needs, but patch testing is recommended for sensitive skin. The product aims to hydrate without leaving a greasy finish, making it compatible with normal, combination, and many oily skin types when used sparingly.

• Non-heavy texture reduces pore-clogging risk
• Patch test if you have reactive skin or allergies
• Use less product if your skin is very oily
• Works well layered under mattifying products

Who is this for: This serum is designed for anyone seeking a luxurious, multi-action step to improve hydration longevity and refine skin texture—ideal for dry or combination skin that benefits from both immediate moisture and a sealing oil phase. It appeals to skincare users who prefer lightweight yet effective products with a premium ingredient profile, including those curious about truffle-infused Korean formulations.
