Collagen plays a key role in maintaining skin structure, firmness, and elasticity. As collagen levels naturally decline with age, the skin may appear thinner, less firm, or more prone to lines and sagging.
At NU.U Aesthetics & Wellness Clinic, collagen restoration is approached through clinically supported treatments guided by medical professionals. With over 21 years of experience in aesthetic medicine, Dr. K. K. Chew and the team provide personalised care based on individual skin needs and treatment suitability.
In this article, we explore seven commonly used treatment approaches that have been shown to support collagen production and skin renewal, guided by scientific research and clinical practice.
Why Collagen Declines and How to Boost It
Collagen is a key structural protein that keeps skin firm, elastic, and hydrated. However, collagen production begins to slow as early as your mid-20s, with a more noticeable decline after age 30.
On average, collagen levels decrease by about 1–2% per year. Several internal and external factors contribute to this decline:
- Ageing: Natural slowdown of fibroblast activity over time
- UV exposure: Sunlight breaks down existing collagen and inhibits new production
- Pollution: Environmental stressors trigger oxidative stress in the skin
- Lifestyle factors: Smoking, lack of sleep, and poor diet can impact skin health
- Hormonal changes: Especially during menopause, can affect skin density and elasticity
In Singapore’s tropical climate, where sun exposure and humidity are constant—daily skin stress can accelerate this process.
How to Support Collagen Production
There is no one-size-fits-all solution, but collagen can be supported through a combination of:
- Healthy skincare habits: Use sunscreen, vitamin C serums, and moisturisers with peptides
- Balanced lifestyle choices: Stay hydrated, eat antioxidant-rich foods, and get adequate rest
- Clinically supported treatments: Some procedures are designed to stimulate collagen renewal by targeting deeper skin layers
These treatments typically work by triggering a controlled healing response, which encourages the skin to rebuild collagen over time. Results are gradual and depend on the type of treatment, skin condition, and frequency of sessions.
Effective Collagen-Stimulatory Treatments Worth Considering
1. RF Microneedling
RF microneedling combines controlled micro-injuries with radiofrequency energy to stimulate collagen and elastin production in the deeper layers of the skin. This method is often considered for those looking to improve skin texture and firmness over time.
Common clinical uses include:
- Supporting collagen and elastin regeneration
- Improving skin tone and surface texture
- Reducing the appearance of enlarged pores or fine lines
What to expect:
- Typically done in a series of 3 to 5 sessions, spaced 4–6 weeks apart
- Mild redness or swelling may occur after treatment, usually subsiding within a few days
- Gradual improvements may be observed over several months
This treatment is generally suitable for a variety of skin types when performed in a clinical setting using appropriate parameters.
2. PDO Threadlift for Collagen Stimulation
Polydioxanone (PDO) threads are medical-grade absorbable sutures inserted beneath the skin. While they provide a subtle lifting effect, their main benefit is in stimulating collagen production during the natural breakdown process.
Potential areas of treatment:
- Jawline
- Mid-face
- Neck
How it supports collagen:
- Threads create micro-channels that stimulate fibroblasts
- Collagen forms along the thread path as the material dissolves
- Improvements in firmness and skin quality develop over time
What to expect:
- Some lift may be visible shortly after the procedure
- Further improvements typically occur over the next 2 to 6 months
- Downtime is minimal, with most individuals returning to normal activities within a few days
A proper consultation is essential to determine if PDO threads are appropriate for your needs.
3. Collagen Biostimulator Injections
These injections use poly-L-lactic acid (PLLA) to gradually stimulate collagen production and restore facial volume over time. In Singapore, they are often used to address areas of soft tissue deflation and early volume loss.
Key points:
- Stimulates fibroblasts to generate new collagen over 1–3 months
- Enhances skin firmness and restores subtle volume
- Often used in cheeks, temples, and facial hollows
What to expect:
- Initial swelling or bruising may occur, typically resolving in days
- Gentle massage is advised post-treatment to ensure even integration of PLLA particles and reduce nodules
- Cumulative results usually develop gradually and can last up to 24 months with proper care
4. Exosome Therapy for Skin Rejuvenation
Exosome therapy uses nanoscale extracellular vesicles rich in growth factors and signaling molecules. It’s offered in Singapore alongside microneedling or topical application to enhance skin repair and support collagen synthesis.
Common applications:
- Following microneedling or laser procedures to accelerate healing
- Improving skin texture, tone, and hydration
- Potential support for collagen and elastin remodeling
What to expect:
- Minimal downtime; some individuals may notice mild redness or tightness
- Reported results include gradual improvements in skin clarity and texture over a few weeks
Important note: Exosome therapy does not currently hold formal dermatology approval in Singapore and should be offered only by qualified medical practitioners under proper protocols.
5. Digital Peel Laser / Fractional CO₂ laser
Digital Peel works as a regenerative laser that gently resurfaces the skin, boosting cell renewal and improving overall texture. In Singapore, these treatments are commonly used for refining pores, reducing pigmentation, and restoring a smoother, more radiant complexion.
Treatment highlights:
- Targets damaged or aged skin by inducing controlled dermal renewal
- Effective at reducing acne scars, pigmentation irregularities, and skin laxity
- Both ablative and fractional modes are available, offering variable depth and downtime
What to expect:
- Recovery time depends on the laser type: non-ablative options require minimal downtime; ablative treatments may need 1–2 weeks for full recovery
- Temporary redness, swelling, flaking, or crusting usually resolve within days to weeks
- Diligent sun avoidance and post‑treatment sun protection are necessary to reduce the risk of pigmentation changes.
6. Platelet‑Rich Plasma (PRP) Collagen Induction
Platelet‑Rich Plasma (PRP) is an autologous therapy, meaning it uses your own blood, to harness growth factors that may support collagen and elastin renewal when combined with microneedling. This technique is often referred to as collagen induction therapy.
Key benefits:
- Microneedling creates controlled micro-injuries, triggering a natural healing response and stimulating collagen formation.
- PRP introduces concentrated growth factors to further support fibroblast activity and tissue repair.
Clinical considerations:
- A small amount of blood is drawn, processed via centrifuge, and the PRP is applied topically or injected.
- Treatments are usually spaced 4–6 weeks apart; many need 2–4 sessions for noticeable changes.
- Side effects like redness or mild bruising are usually short-lived.
When performed under medical supervision, PRP with microneedling is regarded as generally safe and may accelerate the skin’s natural repair and regeneration processes.
Disclaimer: In Singapore, the use of PRP for aesthetic purposes is subject to medical regulations and cannot be advertised as a cosmetic treatment. Patients should consult a licensed medical professional for personalised advice.
7. At‑Home Skincare Rituals: Supporting Professional Treatments
While in-clinic procedures provide deep stimulation, consistent at-home care is essential for supporting collagen maintenance and enhancing overall results.
Key routines and ingredients to consider:
- Vitamin C (ascorbic acid): Antioxidant that stabilises collagen and protects against UV‑induced degradation.
- Retinoids (prescription) or Retinol (lower strength): Promote cell turnover and collagen synthesis; introduce gradually to avoid irritation.
- Peptides & growth factor serums: May support collagen remodeling and skin repair, especially in sensitive skin.
- Exosome-based skincare: Emerging topicals that deliver bioactive signals to encourage skin regeneration and repair.
- Daily sunscreen (SPF 30+): Prevents UV-induced collagen breakdown; essential even on cloudy days.
- Hydration and moisturisation: Improves skin barrier function and supports optimal collagen activity
Lifestyle factors:
- Nutrition: Eat vitamin C‑rich fruits, protein, and omega‑3 foods to support collagen synthesis internally.
- Healthy habits: Adequate sleep, stress management, hydration, and avoiding smoking or excessive alcohol help preserve collagen integrity.
These practices complement in-office treatments by maintaining an environment favourable to collagen renewal and skin resilience over time.
