d'Alba White Truffle Double Serum

The dual-phase formula separates because it contains both oil-soluble ingredients (like white truffle extract) and water-soluble ingredients (like Vitamin C). You must shake the bottle before use to temporarily emulsify these layers into a single, effective treatment. This ensures you get the benefits of both phases simultaneously.

Yes, d'Alba uses a more stable derivative of Vitamin C combined with niacinamide to ensure brightening without rapid oxidation. This makes the serum last longer on your shelf compared to pure L-ascorbic acid serums, which degrade quickly in sunlight. It provides a safer, less irritating brightening effect.

Yes, because it uses a stable Vitamin C derivative, it is safe for daytime use to boost your skin's defense against environmental damage. However, you must always follow up with an SPF of 30 or higher to protect your skin. Vitamin C actually works synergistically with sunscreen to fight free radicals.

Despite containing oil, the micro-emulsion technology in the d'Alba serum allows it to absorb quickly into the skin. Users typically report a lightweight finish, though those with very oily skin might prefer to use it only in their nighttime routine. It is designed to deliver moisture deeply without sitting on the surface.
