This is the question everyone is asking, and to which the market responds with thousands of products. Creams, serums, injections, dietary supplements, complex routines... Faced with this abundance of promises, it's hard to distinguish what really works from what merely sells well. Here's what science says.
Understanding skin aging to better address it
Skin aging is not a single phenomenon. It's the convergence of several biological mechanisms that accelerate with time: declining collagen and elastin production, accumulation of oxidative damage, low-grade chronic inflammation, weakening of the skin barrier, and slowed cell renewal.
From the age of 25, natural collagen production decreases by approximately 1% per year. At 40, Coenzyme Q10, a key antioxidant in skin cells, has lost up to 40% of its concentration in the skin. The lipid barrier thins, water loss increases, and the skin recovers less effectively from daily aggressions.
An effective anti-aging solution must therefore act on these mechanisms simultaneously, not just on one of them.
Skin aging doesn't start on the surface. It starts in the cells, long before wrinkles appear.
What creams can do, and what they cannot do
Topical anti-aging treatments have their uses. A good vitamin C serum protects the skin's surface from environmental oxidative stress. A cream rich in ceramides strengthens the superficial skin barrier. A daily SPF is the most documented anti-aging action there is: photoprotection prevents up to 80% of extrinsic skin aging.
But creams, even the most sophisticated, are limited by a physical reality: active molecules like native collagen or Coenzyme Q10 do not penetrate beyond the superficial layers of the epidermis. Yet it is in the much deeper dermis that the fibroblasts responsible for collagen synthesis are found. This is where oxidative damage accumulates first. And this is where a cream does not reach.
Internal action: acting where creams don't
This is precisely why internal beauty has changed its status in recent years. Not as a marketing trend, but as a scientifically founded approach. Active ingredients taken orally are distributed via the bloodstream to all tissues, including the deep layers of the skin.
Hydrolyzed marine collagen, fragmented into low molecular weight peptides, stimulates dermal fibroblasts to produce more natural collagen and hyaluronic acid. Ceramosides strengthen the skin barrier from within. Coenzyme Q10 protects skin cell mitochondria from oxidative stress. Thymoquinone from black seed modulates systemic inflammation that accelerates aging.
- Type I hydrolyzed marine collagen Stimulates natural collagen production in the dermis. Clinically proven effects on hydration and elasticity from 8 weeks.
- Ceramosides Strengthen the skin barrier, reduce water loss, and improve skin suppleness. +27% hydration gain in 60 days.
- Coenzyme Q10 Protects skin cells from oxidative stress. Its natural production significantly declines from age 30.
- Thymoquinone (black seed) Natural anti-inflammatory and antioxidant, it acts on low-grade chronic inflammation that accelerates skin aging.
- Vitamin E and selenium Complementary antioxidants that protect lipid membranes and amplify the action of the entire antioxidant network.
- Essential fatty acids GLA (borage) Nourish cell membranes, reduce inflammation, and limit transepidermal water loss.
Synergy: why a combined formula is more effective
Since skin aging is multifactorial, a single-ingredient solution can only be partial. Collagen alone does not compensate for an antioxidant deficiency. Antioxidants alone do not rebuild a weakened skin barrier. It is the combination of complementary active ingredients, each targeting a different mechanism, that produces lasting and visible results.
This is the logic that guided the formulation of DE AUREA's Protocol N°79: combining structural, restorative, and protective active ingredients in a single capsule, in their most bioavailable forms and at clinically relevant dosages.
At what age should you start?
The question comes up often, with an answer many don't want to hear: sooner than you think. Your thirties are the ideal time to start supporting the biological mechanisms that naturally decline, before visible signs set in.
Acting preventively is always more effective than acting reactively. It's not a matter of vanity: it's a matter of cell biology. The cells you nourish today are the ones that will determine the quality of your skin in ten years.
The best anti-aging solution is not one that erases time. It's one that gives your skin the resources to age at its own pace.
Frequently asked questions about anti-aging solutions
The best anti-aging solution combines topical action on the surface and internal action. Dietary supplements containing hydrolyzed marine collagen, antioxidants like Coenzyme Q10 and vitamin E, and anti-inflammatory active ingredients like thymoquinone from black seed act on the deep mechanisms of skin aging, where creams cannot reach.
Ideally in your thirties, when the natural production of collagen and Coenzyme Q10 begins to decline. Acting preventively is always more effective than acting reactively. The effects are gradual and lasting, provided regular intake for at least 2 to 3 months.
Yes, provided you choose hydrolyzed collagen in the form of low molecular weight peptides. Several clinical studies show that regular supplementation improves skin hydration, elasticity, and density after 8 weeks. Type I marine collagen is particularly well-documented.
The most well-documented active ingredients for slowing down skin aging internally are hydrolyzed marine collagen, Coenzyme Q10, vitamin E, selenium, ceramosides, and essential fatty acids like GLA. Thymoquinone from black seed complements this panel with its anti-inflammatory and antioxidant properties.
The two are complementary. A cream acts on the superficial layers of the epidermis. A dietary supplement acts from the deep layers via the bloodstream, supporting collagen synthesis, protecting cells from oxidative stress, and modulating systemic inflammation. For lasting results, internal action is essential.
