FAQs – DEKÁRNÉ

Luxury is not an embellishment; it is integrity at the molecular level. It is found in the precision of our actives: 3-O-Ethyl Ascorbic Acid, a stabilized, next-generation Vitamin C, paired with rare Japanese Mushroom Ergothioneine (renowned for its exceptional antioxidant stability), both encapsulated under vacuum conditions to lock in molecular potency. It is assured by the gold-standard stabilizing embrace of Ferulic Acid and Pure Tocopherol, and the barrier-comforting matrix of Ceramides and Phytosterols.

Ultimately, true luxury is preservation. This is why our elixir is housed in an opaque, airless vessel – to ensure the formula you receive is the formula we crafted, at its peak potency. This is the quiet, uncompromising architecture that defines DEKÁRNÉ, far beyond the ordinary.

*Ferulic + Vit E: Gold-standard stabilizers per cosmetic science

It is a recalibration of value, not a premium. Here, you will find the same uncompromising standards – pharmaceutical-grade ingredients like Ergothioneine at ≥98% purity, efficacious levels of stabilized 3-O-Ethyl Ascorbic Acid, vacuum-encapsulated actives for guaranteed potency, and filler-free integrity. These are the hallmarks of serums costing quadruple the price. We’ve simply architectured out the compromise.

Your investment secures the non-negotiables: the freshness of protected molecules, the precision of small-batch craftsmanship, and a formula that delivers pure, sensory elegance. This is the true cost of integrity, presented without the traditional luxury markup.

We believe clarity of purpose is the highest form of care. We forgo added fragrance to eliminate any risk of irritation, ensuring universal elegance for even the most sensitive skin.

What remains is the quiet, honest aroma of our ingredients: the earthy whisper of rosemary extract and the subtle, organic depth of squalane – the true scent of integrity itself.

Through an architecture of preservation, beginning long before formulation. Our key actives are encapsulated under vacuum conditions, a first defense against degradation. Within the formula, a synergistic guard of Ferulic Acid and Pure Tocopherol stabilizes the Vitamin C matrix, while Rosemary Extract and Sodium Phytate neutralize free radicals at the molecular level.

The final safeguard is the vessel: an opaque, airless chamber that locks out light and oxygen. From sourcing to sealing, every layer is designed to ensure the formula you receive is the one we crafted, in a state of perfect, quiet potency.

To foster a respectful dialogue with your skin. Our pH of 5.5–6.0 aligns with skin’s natural mantle, a choice that prioritizes immediate comfort for sensitivity while creating the ideal environment for peptide activity and antioxidant stability. It is a foundational decision for both gentleness and quiet efficacy.

In our elixir, they are chosen for their harmonious duality. Squalane offers a featherlight, silken caress that vanishes into the skin. Phytosterols work with ceramides to help maintain the skin's moisture equilibrium. The experience is one of pure sensory elegance – a quiet veil of comfort that leaves skin feeling balanced, serene, and perfectly prepared.

It is for the mindful individual who values intention over intervention. This elixir is a ritual for those seeking:

A More Luminous Appearance – To help brighten the look of skin, promoting a more even, radiant tone.
A Refined Complexion – To smooth the appearance of skin texture and support more resilient look.
A Deeply Comforting Sensation – To offer a soothing, fragrance-free experience for skin that values simplicity and calm.

It is for anyone who approaches skincare as a quiet, nurturing dialogue – where the goal is not to change, but to reveal the skin’s most balanced, serene state.

Our formula is a study in gentle design. Every element is calibrated to respect sensitivity: a skin-compatible pH of 5.5, the comforting presence of Bisabolol, and the barrier-supporting role of Ceramide NP. We exclude fragrance, alcohol, and essential oils entirely.

It is not simply suitable; it is thoughtfully architected for those who seek uncompromised efficacy with profound gentleness – a quiet dialogue with skin that prioritizes comfort and tolerance.

It is a study in intelligent design. Traditional L-Ascorbic Acid, while potent, is inherently unstable and often associated with irritation. Our 3-O-Ethyl Ascorbic Acid is its evolved counterpart – engineered for superior stability to resist oxidation, formulated at a skin-compatible pH for gentleness, and selected to deliver brightening benefits with lasting reliability.

We chose it not as an alternative, but as an advancement – the precise instrument for our quiet architecture of efficacy, delivering the benefits of Vitamin C through a more reliable, gentle, and considerate form.

*Stability studies show L-ascorbic acid degrades >40% in 8 weeks at room temperature, while ethylated derivatives retain >90% potency (Journal of Cosmetic Dermatology, 2020).

Individual results vary based on skin type and concerns, but consistent daily use (morning and evening) with SPF 30+ helps maximize benefits. This serum is formulated as a high-quality daily maintenance and gradual improvement product, not an instant 'filler in a bottle’ – changes develop cumulatively. You might not notice it on day one. But one morning, you'll catch your reflection and see less fatigue, more light. You'll feel a newfound softness when you rest your cheek on your hand. These are the moments we weave for.

Within 1 week: Skin often feels more hydrated, smoother, and looks refreshed.
Weeks 2-4: Many notice a healthier-looking glow, improved skin clarity, and softened fine lines.
Weeks 4-8: Visible refinement in tone and clarity; with skin feeling firmer and more resilient.
12+ weeks: With continued use, skin often appears more radiant, even-toned, and feels smoother. The look of fine lines and wrinkles may appear minimized, and skin feels comfortably balanced.

*Results focus on the cosmetic appearance and feel of skin. Consistency is key!. Individual experiences vary.

Through a seamless chain of care – from sourcing to sealing. Each ingredient selected undergoes triple verification:

COAs confirming ≥98% purity (e.g., niacinamide, peptides)
Heavy metal screening (≤10ppm)
Stability testing for oxidation/pH drift
