Questions, answered

Skin longevity skincare supports the skin's long-term health and resilience rather than chasing short-term fixes — protecting elasticity, hydration and barrier function over years, not days. Lucis Protecting Day Serum applies this by day: antioxidant defense against oxidative stress, with 67 ingredients at 92% natural origin, in a refillable bottle designed to be kept.

A day serum delivers concentrated actives and antioxidant protection before you face the day. Lucis Protecting Day Serum combines niacinamide, sodium hyaluronate and vitamin C derivatives to hydrate, brighten and defend skin against oxidative stress and urban pollutants.

Lucis is The Nine Aurora's daytime protective serum — 67 ingredients, 92% of natural origin. It pairs antioxidant botanicals from the nine skin-longevity zones with the actives dermatology trusts, for hydration, radiance and daily defense.

Apply in the morning after Ionis Toning Mist. Dispense 2–3 pumps into your palm, warm the serum slightly, then press it gently into face, neck and décolleté. Follow with Lucis Nurturing Day Cream.

Serum first, always. The lighter serum needs to reach the skin directly; the cream then seals it in. Apply Lucis, then follow with your day cream.

Perfetto

Prodotto di buona qualità con una profumazione delicata. Ottima l'idea di poter acquistare solo il refill per evitare sprechi di plastica. Confezione piacevole e curata nei dettagli

Approved!

Ottima texture e profumazione delicata, mai invadente. Lascia sulla pelle una piacevole e duratura sensazione di idratazione. Dopo sole due settimane di utilizzo noto già un miglioramento visibile: la pelle appare più luminosa, morbida e uniforme.

Silky, smooth, and crisp!

It’s a silky, fast-absorbing serum that instantly boosts hydration. After applying it, my skin feels soft and supple—completely different from how tight and dry it usually feels after washing with a regular face soap. When I use it after the Photogena Facial Treatment Cleanser, my skin stays so hydrated that I sometimes forget I haven’t even moisturized yet! It’s lightweight, non-irritating, and smells amazing. I absolutely love it.

Airless touch

The texture is truly incredible—lightweight, silky, and instantly absorbed into the skin without leaving any residue. It feels almost like a second skin, delivering hydration and radiance from the very first application. I also really appreciate the airless refill packaging, which not only preserves the formula perfectly but also reflects a more conscious, luxury approach to skincare.
