Serum with Natural Encapsulated Vitamin C

Hydration is the foundation of skin longevity. That’s why natural hyaluronic acid isn’t just a trendy ingredient—it’s the building block upon which you’ll lay the foundation for your skin’s health. At DHYVANA, we select dual-action molecular weights (10–50 kDa) certified by EcoCert, derived from the natural fermentation of glucose. These work through biomimicry: they repair the outer layers by restoring the natural protective barrier that prevents water loss. Of course, our hyaluronic acid is 100% vegan and GMO-free.

Our Serums with Natural Hyaluronic Acid

Just as with your skin’s structural proteins—collagen and elastin—the skin’s natural moisture reserves decrease over the years. That’s why incorporating a hyaluronic acid serum helps restore this lost moisture and improve your skin’s longevity.

All of our organic skincare products work through biomimicry, and more specifically, our low- and medium-molecular-weight hydrating hyaluronic acid penetrates the skin through this mechanism. The result: they reach the different layers of the skin and deliver the various benefits you expect from a serum— fewer wrinkles, fewer signs of aging, more hydrated skin, and much smoother skin.

Hyaluronic Acid Creams: Biomimetic Sealing

The serum serves a specific purpose: to reach the deepest layers of the skin. In your moisturizer, hyaluronic acid acts as an external shield that works in synergy with your skin’s barrier function. This mechanism is fascinating: without adding extra lipids but by working in synergy with them, it prevents transepidermal water loss. As a result, it balances combination and oily skin, nourishes dry skin, and keeps normal skin perfectly balanced—all without clogging the pores.

Hyaluronic Acid: Frequently Asked Questions

Hyaluronic Acid for Dark Circles: Yes or No?

Absolutely. And here’s why: the eye area (dark circles) requires ingredients that meet several criteria. They need to be highly moisturizing, hypoallergenic, and not overly greasy. The skin in this area is very thin and particularly mobile (just think about how much you move your eyes throughout the day), which is why it’s essential to provide extra hydration.

In this regard, we’d like to remind you of DHYVANA’s Radical Safety principle. If you’re not familiar with this concept, be sure to check out our“Formulation Principles” section; at DHYVANA, we always formulate products for sensitive skin, using no harmful ingredients and eliminating anything that doesn’t benefit your skin. And you’re going to love this: our serums are designed to be applied around the eye area, and so are our creams. In each product’s description, we explain exactly how to use them.

What is hyaluronic acid used for, and how exactly does it work?

It is primarily a hydrating ingredient, and in fact acts like a sponge. Its function is to absorb water, and when combined with other ingredients, it also provides moisturizing benefits: in other words, it helps seal in that water and retain moisture.

The effect of this hydration on your skin depends on its molecular weight. Low-molecular-weight hyaluronic acid penetrates down to the deepest layers. Its effect is less visible to the eye, but in return, it provides deep, long-lasting hydration. This is key to building the foundation of your Skin Longevity. Then there’s medium- and high-molecular-weight hyaluronic acid, which acts on the outermost layers of the skin and strengthens your protective barrier. You’ll notice its plumping effect in the mirror (fewer wrinkles), and it serves as the first line of defense against dehydration.

Which is better? At DHYVANA , we use both complementary approaches, both of which are necessary: low molecular weight (approximately 10 kDa) and medium-to-high molecular weight (up to 50 kDa). This way, you’ll notice visible hydration while simultaneously building a strong, invisible foundation.

When is better, day or night?

Hyaluronic acid really is an ingredient that works wonderfully in all kinds of skincare routines. Since it’s non-greasy, it’s suitable for daytime routines, which are typically lighter, require a more fluid hydration, and allow you to apply makeup or protect your skin from pollution. And most importantly: you shouldn’t skip hyaluronic acid in your nighttime routine. At night, in sync with your skin’s natural repair cycle, it works every day to help your skin build a strong foundation. That’s your daily dose of Skin Longevity.

Rice water is a facial brightener, an Asian secret traditionally used to achieve porcelain-like skin. Rice contains starches and proteins that naturally help even out skin tone, brighten the complexion, soften the skin, and maintain its moisture. Washing rice in water or cooking it produces this rice water, a remedy deeply rooted in Japanese cosmetic tradition.

Rice Water vs. Rice Extract

Although both are derived from rice, the water and the extract are different. Washing and cooking in the form of water extract the compounds to varying degrees. In modern cosmetics, the Oryza sativa extract makes it possible to concentrate and stabilize its properties.

Among them is gamma-oryzanol, an antioxidant that has been shown to affect tyrosinase and MITF, two mechanisms involved in melanin production. This way, we can strategically incorporate it into your routine to better support your skin.

Rice Extract for Radiance

Skin radiance is influenced by many factors. That’s why this extract is so effective: it addresses several key factors, such as hydration, smoothness, pore texture, and uneven pigmentation.

When combined with other strategically selected ingredients, rice transforms from an ancient tradition into an essential component for radiant skin and a protected skin barrier.

Licorice extract (Glycyrrhiza glabra) has a particularly comprehensive skin-toning effect: it acts on pigment while helping to soothe the skin that produces it. It contains glabridin, which reduces the formation of pigment and facial spots by inhibiting the activity of tyrosinase, a key enzyme in melanin production. In addition, liquiritin promotes the dispersion of melanin that has already accumulated, helping to progressively improve the appearance of facial spots. In this way, the former acts on the pigment that is forming, and the latter acts on the pigment that is already visible.

Licorice for irritation-free depigmentation

Facial spots and hyperpigmentation have multiple causes. It’s not enough to target the pigment if the skin remains inflamed or is subjected to oxidative stress. That’s why the soothing effect of licorice is key—it helps reduce the conditions that can fuel hyperpigmentation. Combined with other strategically selected active ingredients, this approach restores luminosity and achieves a more even, radiant complexion without compromising the skin barrier.

Enhances the appearance of the skin by improving the elimination of dead cells, favouring epidermal renewal and providing a more luminous skin.

Vitamin C Ascorbyl Glucoside acts as an encapsulated form of Vitamin C because it uses enzymatic stabilization technology, which releases the vitamin gradually upon contact with your skin. This stabilization with glucose ensures stability, keeping its full potency intact until the moment you apply it to your skin. This results in a more prolonged, steady release without spikes. That way, you get better results without irritation.

Unlike traditional vitamin C (L-ascorbic acid), which is often irritating and unstable, this form of vitamin C is more active and effective even at low concentrations. That’s why it’s our choice—it’s designed to preserve your skin’s longevity while providing maximum antioxidant protection, reducing dark spots, and enhancing your skin’s radiance.

Ascorbyl Glucoside for Hyperpigmentation

Traditional depigmenting agents can sometimes be harsh or unstable and cause inflammation. In cases of hyperpigmentation, this is an even greater concern. Using Ascorbyl Glucoside visibly reduces dark spots, diminishes sallowness in areas with hyperpigmentation, and enhances radiance—all with minimal risk of irritation.

How It Works on Your Skin

• Removes dark spots and evens out skin tone: supports the cell renewal process, gradually reducing dark spots and substantially improving skin tone
• Stimulates collagen and fills in wrinkles: reactivates collagen synthesis in fibroblasts, helping to keep the skin’s cellular structure young, dense, and elastic. In clinical studies, continued use reduced the wrinkle index by 18.9%, resulting in a measurable improvement in skin hydration.
• Antioxidant shield and active photoprotection: neutralizes free radicals, specifically those caused by solar radiation and cellular oxidative stress. This enhances the skin’s natural resistance to damage caused by UV radiation and blue light

Mango Extract, or Melan’oWhite™, is a patented compound specifically designed to act on tissue pigmentation. It has a dual action, renewing cells and inhibiting pigmentation at the cellular level. Clinically, it has been shown to be more effective than kojic acid in treating pigmentation disorders, producing visible, measurable results in 7, 28, and 56 days without causing skin irritation.

Melan’oWhite™ vs. Kojic Acid

Kojic acid is the gold standard among depigmenting agents, especially in Asia. While it is highly effective, the Melan’oWhite™ mango extract offers an action that is not only powerful but also aligned with your Skin Longevity. Its dual action removes dead cells laden with dark pigment from the skin’s surface, while deep within the skin it acts on melanin production by reducing the activity of the enzyme tyrosinase by up to 93.2%. The result: in addition to slowing the appearance of future dark spots (prevention), it reduces the size and perimeter of existing dark spots. The result is an even-toned complexion with fewer dark spots.

How It Works on Your Skin

• Removes dark spots and evens out skin tone: It acts directly on the source of dark spots by inhibiting the enzyme tyrosinase to stop excessive melanin production. It has been clinically proven to visibly reduce and lighten age spots (solar lentigines) after weeks of consistent use, restoring the skin’s radiance and even tone.
• Accelerates cell renewal: Because it is naturally rich in lactic acid, it gently exfoliates, removing dead cells loaded with pigment
• It stops dark spots at their source: it acts directly on the root of the problem by reducing the activity and production of the enzyme tyrosinase, which reduces the production of new melanin by up to 93.2% in laboratory tests
• Visible reduction of existing dark spots: it not only brightens but also reduces the size of dark spots. Clinically, after 56 days of use, it reduces the perimeter of dark spots by 5.0% and their total surface area by 5.5%, revealing an even and radiant complexion
