Serum

The serum is the concentrate of skincare: the lightweight and penetrating formula that delivers active ingredients at maximum concentration — moisturizing, anti-aging, brightening, sebum-regulating. It is the product that has transformed the modern routine: the cream hydrates, the serum treats.

How to choose the right serum

Start with the goal, one at a time: deep hydration (hyaluronic acid), brightness and spots (vitamin C), renewal and wrinkles (retinoids, with gradual introduction), imperfections (niacinamide, exfoliating acids). The golden rule: one new active at a time, to understand what works and what the skin tolerates. Regarding the order of application: the serum should be applied on clean skin, before the cream that seals it — in the morning with a final SPF if using photo-sensitizing actives.

Quality criteria: declared concentration of the active ingredient and protective packaging (airless, dark glass) for unstable molecules like vitamin C.

Frequently Asked Questions

Does the serum replace the cream?

No: they work in tandem. The serum concentrates the actives, the cream hydrates and seals. With a limited budget: a good targeted serum + a simple cream.

Can I use multiple serums together?

With caution: some actives enhance each other, while others can interfere. The safe route is to alternate them (one in the morning, one in the evening) instead of layering them.

How long until I see results?

Moisturizers work in days; actives like retinoids and vitamin C take weeks and months of consistency: the serum rewards patience.
