How to Layer Vitamin C and Peptides: The AM + PM Anti-Ageing Routine
Vitamin C and peptides are two of the most talked-about ingredients in modern skincare and two of the most misunderstood.
Used separately, they each deliver benefits. Used together, morning and night they cover the two halves of the anti-ageing story: protecting the collagen you have by day and stimulating your skin to produce new collagen overnight.
Here's how to layer them properly and why this pairing outperforms almost any single serum on the market.
Why your skin loses its glow (and what actually works)
Skin looks dull, tired and flat for three main reasons: slower cell turnover, dehydration and the gradual breakdown of collagen and elastin. All three accelerate with age, environmental exposure and lifestyle factors.
Most skincare marketing promises to fix all three overnight with a single miracle product. Real, visible change comes from a routine that addresses each of them consistently, over time.
That's where AM + PM layering comes in. Different actives, different times, working together on a 24-hour cycle.
The morning routine: Pro-C Serum
Vitamin C works hardest during the day, when your skin faces the most environmental damage. Applied in the morning the Pro-C Serum can:
Brighten dullness and post-inflammatory pigmentation
Protect existing collagen from oxidative breakdown
Defend the skin against free radicals from UV and pollution
Boost the effectiveness of your SPF when layered underneath
Support natural collagen production over time
What makes Pro-C different from other Vitamin C serums:
Most Vitamin C serums use L-Ascorbic Acid, the unstable form that oxidises quickly, turns brown, and loses potency within weeks of opening. Pro-C uses Tetrahexyldecyl Ascorbate*, a stable, lipid-soluble form of Vitamin C that stays active longer, penetrates deeper into the skin, and delivers consistent brightening and collagen support without the disappointing shelf life.*
How to use it:
After cleansing, apply 1-2 pumps of Pro-C Serum to clean, damp skin. Follow with your moisturiser and finish with a broad-spectrum SPF 50+.
The evening routine: Pro-Peptide Serum
Your skin does its heaviest repair work overnight between roughly 11pm and 4am, cellular regeneration peaks. This is the window where treatment actives deliver the strongest results.
Pro-Peptide Serum is engineered for that window. It combines three clinically-studied peptides (Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Acetyl Hexapeptide-8) with bakuchiol, a plant-derived active that delivers retinol-like collagen benefits without the sun sensitivity or peeling.
Applied at night, Pro-Peptide Serum can:
Signal new collagen production overnight
Reduce the appearance of fine lines and expression lines
Improve skin firmness and elasticity over time
Soften the visible signs of ageing without irritating sensitive skin
How to use it:
After cleansing, apply 2 pumps of Pro-Peptide Serum to clean skin. Follow with your evening moisturiser to seal in the actives.
The synergy: 24-hour anti-ageing coverage
This is where the pairing outperforms either product alone.
During the day, Pro-C is actively defending the collagen you already have from environmental damage. At night, Pro-Peptide is signalling your skin to produce new collagen while you sleep.
Together, they cover the full cycle:
Protect what you have (Pro-C, AM)
Build what's next (Pro-Peptide, PM)
Neither product on its own delivers this coverage. Vitamin C without peptides means you're protecting collagen but not stimulating new production. Peptides without Vitamin C means you're building new collagen while daily environmental damage breaks it down. Paired properly, they multiply each other's effect.
This is what "power couple" means in skincare not a marketing phrase, but a genuine mechanistic synergy.
Your complete AM + PM routine
Morning:
1. Gentle Cleanser
2. Pro-C Serum (1-2 pumps)
3. Your preferred Bloc moisturiser
4. Broad-spectrum SPF 50+
Evening:
1. Gentle Cleanser (or double cleanse if you've worn SPF or makeup)
2. Pro-Peptide Serum (2 pumps)
3. Your preferred Bloc moisturiser (often a richer weight at night)
Simple. Two active steps. Real results.
Realistic timeline for results
Skincare works on the timeline of skin cell turnover every 28 to 40 days - not the timeline of before-and-afters on social media. Here's what to actually expect:
Week 2: skin feels more hydrated, texture starts to soften
Week 4: visible improvement in dullness and surface glow
Week 8: fine lines start to look softer, tone begins to even
Weeks 12-16: real, measurable change in firmness, brightness, and elasticity
Consistency matters more than intensity. Twelve weeks of daily use will do more for your skin than any single "miracle" product used sporadically.
