✨ Understanding healthy skin – structure, cell renewal & molecular care

Our skin is a high-performance organ. It not only protects us from external influences, but is also an active part of our immune system, metabolism, and hormonal balance. To understand skin aging—and counteract it specifically—it's worth taking a look at its complex structure and the mechanisms that keep it healthy.

🔬 Skin structure: protection, care & regeneration

The skin consists of three main layers:

• Epidermis – the outermost layer with horny cells, pH protective layer, barrier function, cell regeneration
• Dermis – the “supporting tissue” with collagen and elastin fibers, fibroblasts, immune cells, capillaries
• Hypodermis ( subcutis) – the deepest layer with fatty tissue, hormone-active cells and temperature buffering

Important substances in the skin:

• Collagen, elastin, the body's own hyaluronic acid, and proteoglycans are formed in the dermis, the middle layer of the skin. More specifically, fibroblasts, specialized cells in the dermis, produce these substances.
  Here is a more detailed breakdown:
  
• Collagen: Synthesized mainly by fibroblasts in the dermis, it forms the supporting framework of the skin.
• Elastin: Also produced by fibroblasts, elastin gives the skin its elasticity and stretchability.
• Hyaluronic acid: An important component of the extracellular matrix that lies between cells, it is also produced by fibroblasts and plays a role in moisture retention.
• Proteoglycans: These macromolecules, which carry glycosaminoglycans (including hyaluronic acid) as carbohydrate side chains, are also produced by fibroblasts and are important for the structure and function of the extracellular matrix.

Fibroblasts are therefore the main players in the production of these important skin components and contribute significantly to the health and structure of the skin.

Cosmetic active ingredients are designed to stimulate the production of these substances in the cells or to supply them. Many products target the epidermis exclusively. However , wrinkles, loss of elasticity, and sagging skin originate in the dermis .

🌟 The amazing abilities of healthy skin

• Synthesis of collagen and elastin for elasticity and firmness
• Self-healing of micro-injuries
• Immune defense and UV protection
• Regeneration through cellular communication
• Balance of lipids, moisture and microbiome

These performances are possible when cell metabolism is active – that is, cells are supplied with sufficient energy, oxygen and nutrients and can communicate with each other.

⚠️ What disrupts skin metabolism

With increasing age or due to environmental influences, cellular processes slow down. Causes include:

• oxidative stress (e.g. due to UV radiation, environmental toxins)
• Incorrect or excessive care, e.g., due to emulsifiers, silicones, aggressive surfactants
• Lack of sleep, unhealthy diet, hormonal imbalances
• chronic inflammatory processes in the skin

The skin becomes sluggish, thinner, regenerates more slowly – and ages visibly.

📉 Superficial effect vs. deep effect

Many cosmetic products contain active ingredients that remain in the epidermis, where they plump the skin superficially or temporarily improve its feel—without any real effect at the deep level.

The dermis often remains untouched. It is the site where special cells ( fibroblasts) primarily:

• produce collagen
• Elastin fibers provide firmness
• Repair processes are initiated

Only active ingredients that reach the dermis can truly support these processes.

🧬 Molecular active ingredients: Small, targeted, effective

Molecular active ingredients are characterized by their small molecular size and high bioavailability. These include:

• Low-molecular hyaluronic acid – penetrates into the deeper layers of the skin, has a hydrating and filling effect
• Peptides – stimulate fibroblasts to produce collagen (such as copper peptides)
• Antioxidants – protect cell structures from oxidative stress
• Biological lipids – stabilize the barrier and improve cell communication. Essential oils can also assume a lipid function, but must be used and dosed with great care in skin care.

The smaller the molecule, the deeper the effect – provided the carrier formulation is skin-compatible.

🔁 Activate cell metabolism – instead of just treating symptoms

True skin rejuvenation occurs through the reactivation of the body's own cellular functions . Modern professional cosmetics therefore work not with film-forming agents or silicones, but with:

• highly bioavailable, molecular active ingredients
• non-irritating pH values
• prebiotic care for the microbiome
• Formulations without microplastics, PEGs or hormone-active filters

Only vibrant, active skin can shine, protect itself – and stay young.

✨ Conclusion: Care that works deep down

Anyone who understands skin knows that it's not about short-term effects, but rather sustainable cellular activity. BEAUÉTAL therefore relies on molecular active ingredients that penetrate the dermis – without overtaxing or blocking the skin.
