d'Alba White Truffle Double Layer Revitalizing Serum: The Original Italian-Korean Hybrid

This is d'Alba's hero product, the one that built the brand's recognition in Korea and expanded it globally. The "Double Layer" format is distinct: an oil phase and a water phase that sit separated in the bottle, requiring a shake to mix before each use. The oil phase contains white truffle extract, squalane, and plant oils; the water phase contains hyaluronic acid, peptides, and botanical extracts. Mixed, they form a temporary emulsion that delivers both layers to skin simultaneously.

The format is cosmetically clever (Korean consumers respond well to visible formulation differences) but also functionally meaningful: keeping the oil and water phases separated until use means fewer emulsifiers and preservatives are needed. At $73.26 for 50ml, this sits in the mid-luxury tier for Korean serums, competing with Sulwhasoo First Care Activating Serum and Laneige Cream Skin.

What It Does

The oil phase (truffle, squalane, plant oils) provides antioxidant and emollient benefits. The water phase delivers peptides, hyaluronic acid, and brightening botanicals. Shaking before each use creates a fresh emulsion that absorbs evenly into skin, providing hydration, antioxidant protection, and collagen signaling in a single application. Over 8 to 12 weeks of daily use, skin shows visible plumping and glow.

Who It's For

• Mature skin (30+) wanting a single multifunctional serum: Primary target.
• Dry to normal skin: The oil phase adds meaningful emollience.
• Vegan luxury skincare shoppers: d'Alba's certified vegan positioning.
• Users who respond to oils in skincare: The emulsified format is gentler than a straight oil.
• Gift buyers: The visually distinct bottle makes a memorable gift.

FAQ

Why dual-phase format?

Keeping oil and water phases separate until use reduces the need for emulsifiers and preservatives, which matters for clean-beauty positioning. Functionally, the user gets a freshly-mixed emulsion each time, which some users find more effective than a pre-emulsified single-phase serum.

Will it work if I don't shake it?

You'll get mostly the water phase with some oil droplets, which is a less effective application. Shake every time for consistent results.

How long does 50ml last?

Twice-daily use at 3 to 4 drops: approximately 2.5 months.

Is this better than Sulwhasoo First Care Activating Serum?

Different products. Sulwhasoo uses fermented ginseng and is marketing-heavy on the hanbang tradition. d'Alba uses truffle and is positioned as Italian-Korean hybrid luxury. For traditional Korean anti-aging: Sulwhasoo. For lighter, vegan-certified, modern approach: d'Alba.

Does it work for oily skin?

Yes, but some oily skin users find the oil phase too rich. For oily skin, apply thinner layers or use only at night.
