Night Repair Therapy

• Visibly reduces fine lines and wrinkles
• Restores skin firmness and elasticity

How It Works- 3 Phases of Repair:

Protect

The first phase shields your skin's healthy cells from damage. Bilberry acts as a potent inhibitor of hyaluronidase, collagenase and elastase the enzymes responsible for tissue degradation. Lycopene, obtained from bio-liquified organic tomato skin, protects from UV-induced, photo-oxidative stress and inflammation.

Renew

The second reparative phase uses retinyl-ester and cell-communicating peptides to rebuild the cellular structure. The synergy of protective and reparative actives allows Night Repair Therapy to trigger collagen and elastin repair and deliver unparalleled results.

Restore

The third phase replenishes and locks in moisture using medium and long chain hyaluronic acid alongside a blend of nourishing botanical oils that retain moisture and soothe the skin barrier.

The Evidence:

Night Repair Therapy is held to the highest standard of scientific testing:

• Double-blind, placebo-controlled clinical studies in human skin
• Published data highlighting significant increase in collagen and elastin — crucial to reversing signs of ageing
• Manchester Patch Test Assay — a rapid in vivo test that predicts an anti-ageing product's ability to restore microfibrils in photoaged skin

KEY BENEFITS

AM: Protects and preserves
Age Defence is clinically proven to reduce daily collagen breakdown, inflammation, and environmental stress. It locks in your nighttime results while providing invisible, encapsulated UV defence. [1]

PM: Renews and strengthens
Night Repair Therapy delivers advanced cellular support up to 20 times more effectively than standard retinol, without the visible irritation typically associated with retinoids. [2]

Supports natural recovery
Daytime DNA repair enzymes work alongside nighttime cell-communicating peptides to provide continuous biological support across a 24-hour cycle. [3]

Deep, round-the-clock hydration
A velvet-matte finish sits well under makeup in the morning. At night, the formula delivers deep nourishment and helps restore the skin barrier while you sleep. [4]

The formula was developed around a central principle: skin health depends on synergy between ingredients rather than isolated actives. Retinyl ester, cell-communicating peptides, antioxidants, and multi-molecular hyaluronic acid are combined so that each component supports and enhances the others.

Protect
Bilberry extract, hydrolysed tomato skin, and niacinamide form the protective layer of the formula.

Bilberry extract inhibits free radical damage. Hydrolysed tomato skin provides defence against photo-oxidative damage. Niacinamide helps maintain healthy skin during environmental exposure.

Renew
Palmitoyl tripeptide-1, palmitoyl tetrapeptide-7, and retinyl palmitate drive the renewal process.

The peptides support collagen synthesis. Retinyl ester promotes skin renewal and cellular turnover.

Restore
Multi-molecular hyaluronic acid, sunflower seed oil, coconut oil, cocoa seed butter, sweet almond oil, and jojoba seed oil work to restore the skin barrier.

Multi-molecular hyaluronic acid supports the barrier and improves the performance of other ingredients. The botanical oils support the lipid barrier and help reduce inflammation.

Question: Will Night Repair Therapy make my skin peel or dry out?
Answer: No. The formula is designed to minimise irritation, including dryness and peeling. Night Repair Therapy uses retinyl ester, a milder form of retinoid that delivers the anti-ageing benefits without the irritation commonly associated with traditional retinoids.

Question: What type of clinical testing has been done on Night Repair Therapy?
Answer: Night Repair Therapy has been tested in double-blind, placebo-controlled clinical trials on human skin. The studies showed significant increases in collagen and elastin production, which are associated with reduced wrinkles and improved skin firmness.

Question: How do I use Night Repair Therapy?
Answer: Apply a pea-sized amount to cleansed skin in the evening. Focus on areas with visible signs of ageing.

Question: Is Night Repair Therapy tested on animals?
Answer: No. Night Repair Therapy is cruelty-free and has not been tested on animals.

Question: How does Night Repair Therapy renew the skin?
Answer: The formula contains peptides and retinyl ester. These ingredients stimulate collagen and elastin production while promoting cellular turnover. Hyaluronic acid, delivered in two different molecular weights, helps maintain skin elasticity and moisture levels for a plump, youthful appearance.

Question: What are the key ingredients in Night Repair Therapy?
Answer: Night Repair Therapy contains a blend of peptides, retinyl ester, bilberry, hydrolysed tomato skin, and two chains of hyaluronic acid. These ingredients are formulated to protect, renew, and restore the skin.

Question: Can I use Night Repair Therapy with other skincare products?
Answer: Yes. Night Repair Therapy can be integrated into your existing skincare routine or into the personalised routines, called Chapters. It is best used after cleansing.

Question: Is Night Repair Therapy suitable for sensitive skin?
Answer: Yes. The formula is designed to deliver anti-ageing benefits without irritation, making it suitable for sensitive skin types. It combines active ingredients with soothing botanicals like bilberry and hydrolysed tomato skin to minimise the risk of irritation.

Question: How long does it take to see results with Night Repair Therapy?
Answer: Visible improvements can be expected within 3 months of consistent use, with continued improvement in the months following. Clinical studies have shown significant increases in collagen and elastin levels over time.

Question: What makes Night Repair Therapy different from other anti-ageing creams?
Answer: Night Repair Therapy uses a three-step approach: protecting healthy cells, renewing damaged ones, and restoring the skin barrier. Unlike other retinoid products, it delivers results without irritation through a balanced blend of peptides, retinyl ester, antioxidants, and advanced delivery mechanisms. It has been tested in double-blind, placebo-controlled clinical trials.

Question: I am sensitive to retinoids. Will I be okay with Night Repair Therapy?
Answer: Clinical testing showed Night Repair Therapy to be well tolerated by sensitive skin and by those with retinoid sensitivity. However, individual skin responses vary. If you have allergies or questions about specific ingredients, the South William Clinic team is available to assist.

Question: Can I use Night Repair Therapy every night?
Answer: Yes. Consistent nightly use is encouraged for best results.

Question: Can I use Night Repair Therapy while pregnant or breastfeeding?
Answer: No. Night Repair Therapy is not recommended during breastfeeding due to the inclusion of retinoids in the formula.

Question: How do I know it works?
Answer: Night Repair Therapy has been held to the highest standard of scientific testing. Its efficacy is supported by double-blind, placebo-controlled clinical studies conducted on human skin.
