d'Alba White Truffle Double Layer Revitalizing Serum: Bi-Phase Serum for Morning Radiance

d'Alba's Double Layer Revitalizing Serum is a two-phase formulation: an oil layer and a water layer that separate in the bottle and are shaken to emulsify before use. The oil phase delivers white truffle extract and nourishing lipids; the water phase delivers hydration and plant extracts. When shaken, they form a silky serum with both hydration and nourishment benefits in a single layer. At 30ml and $66.95, this is d'Alba's signature serum and the most-recognized product in the brand's lineup.

Bi-phase (or two-layer) serums are a distinctive K-beauty format that marketers love for the visual drama and formulators defend as a way to combine ingredients that wouldn't stabilize in a single emulsion. For d'Alba specifically, the water/oil separation maintains white truffle extract stability in the oil phase while the hydration stays bioavailable in the water phase. Shaking before use emulsifies them fresh each application.

What It Does

The oil phase delivers white truffle extract (the brand's hero), nourishing oils, and lipid-based actives that support barrier and radiance. The water phase delivers humectants, botanical waters, and hydration. Shaking emulsifies them into a silky serum that absorbs quickly without residue. Over 4 to 8 weeks, skin looks more hydrated, more luminous, and smoother. Works best in AM for morning radiance routines.

• Pre-makeup glow prep: Silky finish primes skin for foundation or no-makeup looks.

How to Use

Shake the bottle 10 times before each use to emulsify the two phases. Dispense 2 to 3 drops into palms, press onto clean, slightly damp skin. Best used in AM for morning radiance, though PM use is fine too. Follow with moisturizer and SPF. 30ml lasts approximately 2 to 3 months with daily use.

FAQ

Do I actually need to shake it?

Yes. The oil and water phases separate naturally in the bottle. Without shaking, you'll dispense either mostly oil or mostly water, not the emulsified serum. 10 vigorous shakes emulsify the contents sufficiently for even application.

How does this compare to the Vegan First Spray Serum?

Different formats and focus. The Double Layer is bi-phase (serum format, pat application). The First Spray is a single-phase spray (mist format, spray application). For a dedicated serum step, Double Layer. For all-day spray refresh or travel convenience, First Spray.

Is this comedogenic?

Generally no. The oil phase uses lighter botanical oils, not heavy occlusives. For oily acne-prone skin, it's usually well-tolerated; for fungal-acne-prone skin, check the specific oil list against fungal-acne safe guidelines.

Can I skip moisturizer after this?

In humid weather or for oily skin, yes; this serum alone can replace moisturizer in a minimalist routine. For dry skin, follow with a cream for occlusive sealing.

How long until I see radiance improvement?

Immediate glow from the oil-phase nourishment. Sustained radiance: 2 to 4 weeks. Fine-line softening from white truffle and Volufiline-adjacent actives: 6 to 10 weeks.
