Collagen Synthesis

Ageing & Fine Lines

Visible fine lines, wrinkle deepening, loss of skin density, and accelerated ageing driven by UV exposure and collagen decline.

What is Ageing & Fine Lines?

Skin ageing is driven by two processes. Intrinsic ageing is the natural, genetically programmed decline in collagen production, elastin quality, and cell turnover that occurs with time. Extrinsic ageing, also called photo-ageing, is caused by environmental factors, with UV exposure being the largest single contributor, followed by pollution, smoking, and poor sleep. Extrinsic ageing accounts for the majority of visible signs, which means that preventative care from a relatively young age has a significant impact on how skin ages over time.

Common Causes

UV exposure causing photo-ageing and collagen degradation
Natural decline in collagen and elastin production from the mid-20s onwards
Repetitive facial movements that deepen expression lines over time
Smoking, which reduces collagen synthesis and constricts blood flow
Pollution generating free radicals that break down collagen
Poor sleep, chronic stress, and a low-antioxidant diet

What To Look For

Key Ingredients

Tap an ingredient to learn more

Retinol

Accelerates cell turnover and stimulates collagen synthesis, with the strongest evidence base among OTC anti-ageing actives

Tretinoin

Prescription retinoic acid with the most potent and well-evidenced anti-ageing effects

Peptides

Signal fibroblasts to produce more collagen and elastin

Vitamin C

Inhibits melanin, neutralises free radicals, and is a cofactor in collagen synthesis

Glycolic Acid

Resurfaces the skin surface and stimulates dermal collagen at higher concentrations

SPF

The single most evidence-backed preventative measure against photo-ageing

How to Treat

Routine & Care

The most evidence-backed anti-ageing routine centres on three principles: daily broad-spectrum SPF to prevent further photo-ageing, a retinoid to drive collagen renewal and cell turnover, and an antioxidant serum to neutralise free radical damage. Everything else is supportive.

Steps

1 Cleanse morning and evening with a gentle cleanser.
2 Apply a vitamin C serum every morning after cleansing, before moisturiser and SPF.
3 Apply a broad-spectrum SPF50 as the final morning step. This is the most important anti-ageing product in any routine.
4 In the evening, use a retinoid after cleansing. Start with retinol at 0.025 to 0.05% and increase concentration gradually over months.
5 Layer a peptide serum on evenings when a retinoid is not used, or apply after the retinoid has absorbed.
6 Use a hydrating moisturiser morning and evening to maintain the moisture gradient needed for healthy barrier function.

What to Avoid

SPF skipping, which undoes the effect of every other anti-ageing active in a routine
Overusing retinoids at high concentration without building up tolerance, which disrupts the barrier
Smoking, which reduces topical active efficacy and accelerates collagen breakdown independently

Pairings & Interactions

Often Occurs With

antioxidants

Vitamin C in the morning and retinoids in the evening is the most evidence-backed dual approach to collagen preservation and renewal

peptides

Peptides support structural repair and can be used on alternate evenings with retinoids or layered carefully in the same routine

hydrating

Hydrated skin tolerates retinoids better and shows improvements in fine line appearance more quickly

spf-mineral

SPF is the single most effective anti-ageing intervention; no other active delivers comparable protection against photo-ageing

May Worsen

aha

Combining AHAs and retinoids on the same evening risks significant barrier disruption; use on alternating nights

Frequently Asked Questions

What age should I start using anti-ageing skincare?

Daily SPF and antioxidants are worthwhile from the early 20s as preventative measures. Retinoids and peptides become most relevant in the mid to late 20s, when the rate of collagen production naturally begins to slow. Starting early with low concentrations and consistent SPF produces better long-term results than beginning in your 40s with high-strength actives.

Is retinol or tretinoin better for fine lines?

Tretinoin is more potent. It is already in the active retinoic acid form and does not require conversion by the skin, producing faster and more significant results. Retinol requires multiple conversion steps, reducing efficacy but also reducing irritation. Tretinoin requires a prescription in the UK. For many people, a well-formulated retinol used consistently over a year produces meaningful results, while tretinoin produces comparable results on a faster timeline.

Can you reverse existing sun damage with skincare?

Partially. Topical retinoids, vitamin C, and AHAs can improve the appearance of sun-damaged skin by stimulating collagen, accelerating cell turnover, and fading pigmentation. However, they cannot fully reverse deep structural changes to the dermis. In-clinic treatments such as laser resurfacing, chemical peels, and radiofrequency address deeper photo-ageing more effectively.

Do peptides really work for anti-ageing?

Certain peptides have well-evidenced effects. Matrixyl (palmitoyl tripeptide-1 and -7) has clinical evidence for stimulating collagen and reducing fine line depth. Copper peptides (GHK-Cu) have documented wound-healing and collagen-supporting effects. Results are gradual, and peptides are generally considered complementary to rather than a replacement for retinoids and SPF.

Does SPF actually prevent ageing, or just sunburn?

SPF prevents ageing more than almost any other intervention. UV radiation accounts for approximately 80% of visible facial ageing. Daily SPF use, applied correctly and consistently, prevents collagen degradation, pigmentation, and loss of skin elasticity. A well-cited study demonstrated measurable skin quality improvements in people who used SPF daily compared to those who used it only occasionally, independent of any other actives.
