d'alba Piedmont Revitalizing Double-Layer Serum 1.01 fl.oz — White Truffle & Hyaluronic Hydration

d'alba Piedmont Italian White Truffle Double Layer Revitalizing Serum is a dual-phase Korean serum that delivers concentrated hydration and skin-firming support using white truffle, hyaluronic acid, and centella asiatica.

This double-layer formula combines an oil-rich top phase with a water-based base to target dry, tired skin. Designed to be mixed and applied as a single serum, it aims to replenish moisture, soothe irritation, and give skin a more resilient feel. The lightweight texture absorbs quickly while leaving a dewy finish, making it suitable for layering under moisturizers or makeup. Key actives include Italian white truffle extract for antioxidant-rich nourishment, multi-molecular hyaluronic acid for staged moisture delivery, and centella asiatica to calm and support the skin barrier.

How does the double-layer system work for everyday routines?

The serum separates into an oil layer and a water layer that you shake together before use, delivering both emollient and hydrating benefits in one step. It simplifies morning and evening routines by combining nourishment and hydration without feeling heavy.

• Shake bottle to emulsify oil and water phases.
• Apply 2–3 drops to face after cleansing and toning.
• Absorbs quickly, suitable under moisturizer or sunscreen.

What hydration results can I expect and how long do they last?

Formulated with multi-weight hyaluronic acid, the serum targets surface and deeper hydration layers for sustained moisture. While individual results vary, the product is designed to maintain a plumper, more supple appearance for many hours after application.

• Multi-molecular hyaluronic acid delivers layered hydration.
• Claims of prolonged hydration from the blend of oil and humectants.
• Leaves skin with a dewy, refreshed look ready for makeup.

Is this serum suitable for sensitive or aging skin?

Centella asiatica and the gentle formulation make it compatible with sensitive complexions looking for soothing hydration. The nutrient-rich white truffle and supportive ingredients aim to help skin feel firmer and more elastic without heavy irritation.

• Centella asiatica soothes redness and supports barrier recovery.
• Lightweight texture minimizes pore-clogging risk.
• Can be incorporated into anti-aging regimens for firmness support.

How do I layer this serum with other products?

Apply the serum after cleansing and toning but before thicker creams or oils. It pairs well with vitamin C in the morning and retinoids at night when used in separate steps, helping to maintain hydration and comfort during active ingredient use.

• Use after toner, before moisturizer and SPF.
• Allow a minute to absorb before applying heavier treatments.
• Avoid mixing directly with strong acids; layer them in separate steps.

Who is this for: This serum is aimed at people seeking a versatile, lightweight hydrating treatment that blends oil and water phases for extended moisture. Ideal for normal to dry, sensitive, or maturing skin types that want a dewy finish, gentle calming ingredients, and a formula meant for daily morning and evening use. It’s also a good pick for shoppers who prefer multi-functional products that simplify their skincare shelf without sacrificing active benefits.
