Le Sérum Jour is the Strengthen step of our 4S philosophy.
ADVANCED EXOSOME COMPLEX
Within the formula, botanical exosomes bring a new generation of biotech protection. These cell-signalling messengers work with the skin’s own communication systems to support resilience, clarity, and natural renewal. They help reinforce the skin’s biological defences against the daily stressors that accelerate visible ageing.
VITAMIN B COMPLEX
A precision blend of three essential B vitamins. Niacinamide dosed at 3% reinforces barrier strength, helps regulate visible redness, and supports a more even tone. B6 and B9 complete the complex by supporting the cellular processes that keep skin functioning steadily.
STABILISED VITAMIN C
Ascorbyl Tetraisopalmitate, an oil-soluble form of vitamin C selected for its stability and skin compatibility. It supports antioxidant defence, helps protect against free-radical stress, and contributes to a clearer, more even-looking complexion. Unlike pure ascorbic acid, this form is less prone to oxidation and better suited to a daily barrier-first formula.
GRAPE FERMENT EXTRACT
Naturally produced when skin is exposed to sunlight, vitamin D plays a critical role in skin biology. This bioactive extracted from grapesnaturally mirrors the action of vitamin D proteins in skin, supporting the barrier function, antimicrobial defence, and cellular balance that define resilient skin.
HYALURONIC ACID
Maintains hydration through the day, holding water at the skin’s surface for sustained suppleness and comfort.

The day serum combined with the day cream keep my skin bouncy and prevent acne. I used to always get acne in the lower side face and near the chin but literally have not experienced it since I started using Olerique products! I also had dull skin, and now it feels a lot more alive and looks brighter. I can’t even describe how much this changed my skin and my confidence. I’m obsessed.
A beautiful formula and so easy to integrate into my routine! Have been looking for an anti-oxydant and gentle formula for so long and so happy with the results.
I really enjoyed using it, because I felt a real effect over the way my skin looks throughout the day. The day serum is very effective when it comes to securing a glow on the face. I would choose it for its effectiveness and its ease of use: simple and quick, perfect for my lifestyle!
I love it. It absorbs really quickly, and you only need a small amount. The texture feels beautiful on the skin, lightweight but still nourishing, and it sinks in almost instantly without feeling sticky. My skin absorbs it so well, and I genuinely feel like it has helped improve my discoloration and overall complexion.
