Why does the skin lose elasticity — and what can you do about it?
After age 25, the body produces 1–1.5% less collagen each year. By age 40, this difference becomes noticeable: the skin loses elasticity, fine wrinkles appear, and moisture decreases. But it’s not just age — stress, unbalanced nutrition, lack of sleep, and ultraviolet exposure accelerate this process at any age.
Cosmetic products only work on the surface. Real change starts from within — when the body receives the building material to synthesize its own collagen and elastin. This is why Andriy Duyko, founder of Tibetan Formula and a phytotherapist with 20+ years of experience, developed the Liquid Amino Acid Complex — a unique product for internal skin support.
What are amino acids and why are they important for the skin?
Collagen is a protein made up of amino acids. For the body to synthesize collagen, it needs specific "building blocks": glycine, proline, lysine, alanine, and valine. Without enough of these amino acids, collagen synthesis slows down, even if you take vitamin C or other supplements.
The liquid form has a significant advantage over tablets and capsules: amino acids in dissolved form are absorbed much faster — already in the mouth and stomach, without the need for additional breakdown.
Composition: what’s inside each serving?
One serving (15 ml) of the Amino Acid Complex contains:
| Amino acid | Amount | Role for the skin |
|---|---|---|
| Glycine | 906 mg | Main component of collagen (33% of the molecule), regulates synthesis |
| L-alanine | 684 mg | Supports protein structure, involved in metabolism |
| L-proline | 681 mg | Key for the stability of the collagen helix |
| L-valine | 504 mg | Essential amino acid, tissue repair |
| L-lysine | 99 mg | Necessary for "cross-linking" collagen fibers |
This composition is no accident. It precisely replicates the amino acid profile of type I collagen, which is the main structural protein of skin, tendons, and bones.
Mechanism of action: how does it work?
After taking the liquid complex, amino acids quickly enter the bloodstream and are delivered to fibroblasts — cells responsible for synthesizing collagen and elastin. Several key processes then occur:
- Stimulation of collagen synthesis — glycine and proline are direct substrates for the formation of collagen chains
- Dermal hydration — glycine acts as an osmoregulator, retaining water in tissues
- Elasticity restoration — L-lysine participates in forming cross-links between collagen fibers, ensuring firmness
- Antioxidant protection — L-proline protects collagen structures from oxidation
- Tissue regeneration — L-valine accelerates the repair of damaged skin cells
Result — the skin receives exactly what it needs for self-renewal, not just an external coating.
Who is the liquid amino acid complex suitable for?
The product is designed for a wide range of people who care about their skin condition:
- Women aged 25–55 — prevention and correction of age-related skin changes
- Men who actively engage in sports — tissue recovery after strain, reduction of stretch marks
- People after weight loss — skin tightening, reduction of stretch marks
- Those recovering from illness — accelerating regeneration
- Pregnant and postpartum women — with doctor’s approval, to support skin elasticity
- People with dry or dull skin — internal hydration and restoration of radiance
How to take: dosage and course
Recommended intake schedule:
- Dosage: 15 ml (1 tablespoon) per day
- Time of intake: in the morning on an empty stomach or between meals
- Method: pure or diluted in a small amount of water
- Course duration: minimum 1 month, optimal — 2–3 months
- 280 ml bottle designed for approximately 18–19 days of use
For maximum effect, we recommend combining with vitamin C (a cofactor in collagen synthesis) and adequate water intake — at least 1.5–2 liters per day.
Synergy with other Tibetan Formula products
The amino acid complex perfectly complements other products for skin beauty and health:
- Collagen Forte 1000 mg — ready hydrolyzed collagen tablets for joints, skin, and hair. The perfect complement: amino acids support the synthesis of your own collagen, while Collagen Forte provides additional exogenous collagen
- Organic Sulfur — MSM (methylsulfonylmethane) is essential for collagen and keratin synthesis. Combined with the amino acid complex, it provides a powerful effect for skin, hair, and nails
- Hyaluronic Acid 120 mg — retains moisture in the dermis, enhances the moisturizing effect of amino acids. Together — comprehensive skin care from within
Advantages of liquid form over tablets
| Parameter | Liquid form | Tablets/capsules |

| Absorption | Up to 98% (starts in the mouth) | 60–80% (after breakdown) |
| Speed of action | 15–30 minutes | 1–2 hours |
| Convenience | No need to swallow pills | Water required |
| Suitable for | For everyone, including those with digestive issues | For most people |
