One of the most elegant and evidence-backed ingredients is oral ceramosides, a patented class of phytoceramides whose clinical data show real benefits in hydration, barrier repair, elasticity, wrinkle depth, and even hair quality.

At Agent Nateur we chose ceramosides as one half of holi (radiance) for their unique ability to nourish both skin structure and glow from within. They are gluten free and designed for gentle, sustainable beauty support.

Let’s dive into how ceramosides work, what the studies say, and why they outperform colostrum when it comes to visible beauty.

What are ceramosides (oral phytoceramides)?

Oral ceramosides are plant-derived ceramides (phytoceramides) that you ingest. In patented French formulations they are highly refined and standardized to deliver phytoceramide lipids and boosters like digalactosyl diglycerides for better absorption. These compounds help replenish the ceramide lipids in your skin barrier from the inside out. Their mission is structural: restoring the lipid matrix of the epidermis, reinforcing barrier function, and enhancing skin resilience.

Clinical evidence for beauty benefits

Skin hydration, barrier repair, elasticity, wrinkle improvement

• In controlled clinical studies, ceramosides (both in oil form and powder) showed significant improvements in skin hydration, barrier function, and elasticity versus placebo after only two weeks of supplementation (versus baseline).  
• That same data shows reduced wrinkle depth and better elasticity after 56 days, with sustained effects even after stopping the supplement.  
• A randomized, double blind study of oral ceramide-containing bacteria over 12 weeks showed improved stratum corneum hydration (i.e. moisture in the outer skin) without adverse effects.  
• Animal and human evidence suggests that orally ingested ceramides or glycosylceramides can reach skin tissues or at least stimulate ceramide synthesis in skin, improving dry skin, redness, and roughness.  
• In trials with wheat polar lipid complex (a ceramide-rich extract) the supplement also showed dual action on both hair and skin quality, improving hair density, decreasing hair shedding, and reducing scalp oiliness in women over 84 days.  

These studies show that ceramosides support:

• Deep hydration
• Stronger barrier (less water loss)
• Softer, smoother texture
• Reduced wrinkle depth
• Enhanced hair growth, density, and resistance to breakage

Acne scar benefits: why ceramosides may help

While no human trials target acne scars specifically, the mechanisms of ceramosides suggest they can support scar appearance:

1. Barrier repair and inflammation control
   A well-functioning skin barrier keeps irritants, bacteria, and inflammation at bay. Ceramides reduce transepidermal water loss and stabilize pH, which lowers the tendency for post-inflammatory hyperpigmentation or scar widening.
2. Improved remodeling and dermal support
   By deep moisturizing and improving elasticity, ceramosides can make the skin more supple. Scar tissue is often rigid; better hydration and pliability may help the skin texture appear smoother and less indented over time.
3. Supporting collagen environment
   Healthier skin barrier and reduced chronic inflammation create a more favorable environment for collagen regeneration and remodeling. Combined with other actives (like peptides, retinoids, or stem cell signals), ceramosides may augment scar recovery.

Though speculative, it is reasonable to believe that long-term use of oral ceramosides could support the appearance of acne scars when paired with appropriate treatments.

Top beauty benefits of ceramosides

Here's what ceramosides offer for beauty:

• Deep hydration and reduced dryness
• Stronger barrier and less sensitivity
• Enhanced elasticity and firmer skin
• Wrinkle depth reduction
• Better skin texture and radiance
• Support for hair vitality (thicker, more resilient, less shedding)
• Compatible with sensitive skin because it works inside the skin and often helps reduce reactivity
• Gluten free (important for many beauty seekers)
• Synergistic with structural actives like collagen or ceramide precursors

In holi (radiance), ceramosides help smooth your skin from the inside, support hair strength, enhance glow, and reduce the appearance of fine lines.

How to use:

• Take your ceramoside formula (as in holi (radiance)) daily, in a full glass of water with lemon, protein shake or fruit smoothie
• Be consistent, as many benefits emerge after 2 to 8 weeks of regular intake
• Pair with topical treatments for scars (like microneedling, peptides, or gentle resurfacing) so the skin nurtures itself internally and externally
