As we age, the skin gradually loses collagen and moisture, which can affect its firmness, elasticity, and texture. Amino Acid Replacement Therapy (AART) is a non-surgical injectable treatment that combines amino acids, hyaluronic acid, and peptides to help support the skin’s structure, hydration, and repair processes.
These components work together to complement the body’s natural ability to maintain healthy connective tissues. Amino acids act as the building blocks of collagen, while hyaluronic acid helps retain moisture and support fibroblast activity, the cells responsible for collagen renewal. Peptides further assist in maintaining tissue strength and organization over time.
AART is performed under medical supervision and may be suitable for individuals seeking to support skin and connective tissue health in a non-surgical manner. To determine suitability, schedule a consultation with a licensed practitioner, such as those at NUU Aesthetics & Wellness.
What Is Amino Acid Replacement Therapy (AART)?
Amino Acid Replacement Therapy delivers a targeted blend of amino acids and hyaluronic acid into specific areas of the skin and connective tissues to help maintain collagen and hydration. This approach is intended to support the body’s natural repair functions and overall tissue integrity.
When administered by a qualified professional in an MOH-approved clinic, AART helps sustain the extracellular matrix (ECM), the network that provides the skin with structure, firmness, and flexibility.
How AART Works
The Science Behind Amino Acids and Hyaluronic Acid
- Amino acids such as glycine, proline, leucine, and lysine serve as the fundamental components of collagen and elastin.
- Hyaluronic acid helps retain water within the skin’s layers and supports fibroblast activity for balanced collagen renewal.
Together, they maintain the extracellular matrix (ECM), a structure that keeps the skin firm, elastic, and hydrated.
Peptides and Cellular Support
Peptides in the AART formulation work alongside amino acids and hyaluronic acid to help fibroblasts maintain tissue strength and structure. Together, they support a balanced environment within the skin and connective tissues, improving elasticity and moisture retention.
The treatment uses both low- and high-molecular-weight hyaluronic acid to hydrate different skin layers and sustain fibroblast activity. Its amino acid blend, including glycine, proline, lysine, alanine, valine, and arginine, contributes to collagen renewal and helps prevent stiffness caused by collagen glycation.
Biomimetic peptides such as Acetyl Decapeptide-3 and Acetyl Tetrapeptide-5 further enhance fibroblast function and tissue regeneration, promoting smoother, more resilient skin over time.
Treatment Areas That May Benefit from AART
Amino Acid Replacement Therapy (AART) may be considered for several areas of the body where collagen and hydration play an essential role in maintaining structure and resilience.
Common treatment areas include:
- Face, neck, and décolletage: to help support skin firmness and elasticity in areas commonly affected by natural collagen decline.
- Hands: to assist in maintaining hydration and skin texture.
- Ligaments and other connective tissues: to support tissue strength and flexibility through collagen maintenance.
AART is designed to assist collagen preservation and hydration in these regions, contributing to overall tissue integrity. However, suitability and outcomes vary between individuals and should always be assessed by a licensed practitioner.
Potential Benefits of AART
When administered under professional supervision, AART may help to:
- Support collagen and elastin structure to promote natural elasticity and firmness.
- Maintain deep hydration through hyaluronic acid, improving overall skin suppleness.
- Promote tissue resilience by reinforcing the extracellular matrix within the skin and connective tissues.
- Aid joint or ligament comfort through enhanced structural support and hydration.
- Contribute to smoother, healthier-looking skin by supporting balanced moisture and collagen integrity.
The combined amino acid and hyaluronic complex works in harmony with the body’s natural functions to help maintain skin structure, moisture balance, and overall tissue health.
AART vs Other Collagen Stimulation Methods
When considering collagen-supporting treatments, it is important to understand that each method works differently. The following table provides a general comparison between AART and other commonly known collagen-stimulating approaches. This comparison is for educational purposes only and does not imply superiority.
| Aspect | AART (Amino Acid Replacement Therapy) | PRP (Platelet-Rich Plasma) | Skin Boosters |
| Composition | Amino acids, hyaluronic acid, and peptides | Platelets and growth factors derived from the patient’s own blood | Primarily hyaluronic acid-based formulations |
| Mechanism | Supports collagen structure and hydration within the extracellular matrix (ECM) | Delivers growth factors that promote natural tissue repair | Hydrates the skin and improves texture through moisture retention |
| Purpose | Maintain elasticity and support tissue integrity | Encourage regeneration and healing | Enhance surface hydration and radiance |
| Administration | Injected by licensed practitioners in MOH-approved clinics | Injected by licensed practitioners using blood-derived plasma | Injected superficially into the skin’s layers |
While PRP and skin boosters focus on different biological pathways, AART provides nutrient-based support using amino acids and hyaluronic acid to help sustain collagen and tissue health.

Treatment Process
The AART procedure follows a structured approach to ensure safety and individual suitability. Each step is performed by a qualified practitioner in a controlled clinical setting.
Step 1: Consultation and Assessment
A licensed practitioner will review your skin condition, medical history, and treatment goals to determine whether AART is an appropriate option. This step ensures that the treatment plan aligns with your individual health profile.
Step 2: Preparation and Injection
Once assessed, the amino acid–hyaluronic acid solution is gently injected into targeted areas using fine, sterile needles. This process is conducted with precision to ensure comfort and consistency throughout the session.
Step 3: Aftercare and Recovery
Following the procedure, you may experience mild tenderness or redness, which typically subsides within a short period. Practitioners will provide personalised aftercare guidance to help maintain comfort and skin balance.
No fixed results or timelines should be expected, as responses vary by individual.
Safety and Suitability
AART should only be performed by licensed practitioners in MOH-approved facilities.
The treatment is generally well-tolerated when performed by trained professionals. However, it may not be suitable for individuals who are:
- Pregnant or breastfeeding
- Managing autoimmune or chronic conditions
- Allergic or sensitive to any components of the formulation
Before proceeding, a full consultation and medical evaluation are required to ensure safety and suitability.
Note: Individual experiences vary. Always seek professional medical advice before undergoing any aesthetic procedure
