For decades, aesthetic medicine has been about adding — adding volume, filling lines, smoothing the surface. At Dermoperfection in Birmingham, we work to a different principle: the science of self-repair. Rather than masking the signs of ageing, regenerative aesthetics works with your skin’s own biology, switching on the natural processes that rebuild collagen, elastin and healthy tissue from within. The result is skin that doesn’t just look filled — it looks genuinely renewed.

What is regenerative aesthetics?

Regenerative aesthetics is a category of clinician-led treatments that stimulate the body to repair and rebuild its own structural tissue. Instead of relying solely on synthetic volume, these treatments deliver signals — peptides, polynucleotides, biostimulatory particles or controlled micro-injury — that prompt fibroblasts (the cells responsible for collagen) to get back to work. Over weeks and months, the skin becomes firmer, more elastic and better hydrated because you have made new tissue. It is a slower, more natural-looking trajectory, and for many people a more satisfying one.

Polynucleotides: repairing at the cellular level

One of the most exciting tools in this field is the polynucleotide. Derived from purified DNA fragments, polynucleotides are powerful bio-stimulators that hydrate the skin, reduce inflammation and encourage cellular turnover. They are particularly effective around delicate areas such as the under-eyes, where they improve quality and tone without adding heaviness. You can read more about our approach on our dedicated polynucleotides in Birmingham page.

A closely related innovation is the salmon sperm facial in Birmingham — a polynucleotide-based treatment that has earned its reputation for delivering a luminous, “lit-from-within” glow. Despite the headline-grabbing name, it is a serious, evidence-led regenerative treatment that improves skin quality at the foundational level.

Profhilo: bio-remodelling for laxity

As we age, the skin loses hyaluronic acid and the scaffolding that holds it taut. Profhilo addresses this with one of the highest concentrations of hyaluronic acid available, but rather than acting as a filler it spreads through the tissue to bio-remodel — hydrating deeply and stimulating four types of collagen and elastin. It is ideal for crepey, lax skin on the face, neck and décolletage. Explore the treatment on our Profhilo Structura in Birmingham page.

Sculptra: rebuilding collagen architecture

Where deeper structural loss has occurred, Sculptra offers a regenerative answer. Its poly-L-lactic acid particles act as a biostimulator, prompting a gradual, natural rebuild of the skin’s collagen framework over several months. The effect is subtle restoration of facial structure and firmness — not a sudden change, but a quiet return of support that can last up to two years. Learn more on our Sculptra treatment page.

Fractional CO2 laser: resurfacing and renewal

Regeneration isn’t only about injectables. Controlled, fractional energy can trigger the same wound-healing cascade that drives new collagen. Our CO2 laser in Birmingham treatment creates microscopic channels in the skin that stimulate a powerful repair response, softening scarring, texture and fine lines while tightening the surface. It pairs beautifully with injectable bio-stimulators as part of a complete self-repair plan.

Building a personalised self-repair plan

No two faces age the same way, which is why regenerative aesthetics works best as a tailored programme rather than a single appointment. At a consultation we assess your skin quality, structural changes and goals, then combine the right treatments — perhaps polynucleotides for skin quality, Profhilo for laxity, Sculptra for structure and a laser for surface renewal — sequenced over time. This layered, clinician-led approach is the heart of what we do at Dermoperfection.

Ready to rebuild from within?

If you’re drawn to results that look like the best version of you — not a different one — regenerative aesthetics is worth exploring. Book a consultation at our clinic in The Mailbox, Birmingham, and we’ll design a self-repair plan around your skin’s own remarkable ability to heal.

Tretinoin is a prescription-only retinoid — a vitamin A derivative and one of the most evidence-backed topical treatments for acne, pigmentation and the visible signs of skin ageing. Because tretinoin is a prescription-only medicine (POM) in the UK, it cannot be bought over the counter; it must be prescribed after a medical assessment. This guide explains what tretinoin is, the strengths available, how it is used, and how to access tretinoin safely and legitimately in the UK.

What is tretinoin?

Tretinoin (all-trans retinoic acid) is the active, prescription-strength form of vitamin A. Unlike retinol — a gentler ingredient found in over-the-counter serums — tretinoin works directly in the skin without needing to be converted, which is why it is more potent and only available on prescription. It speeds up cell turnover, supports collagen production and helps unclog pores, improving the skin’s tone, texture and clarity over time.

What does tretinoin treat?

Clinicians prescribe tretinoin for a range of skin concerns, including:

• Acne — by keeping pores clear and reducing breakouts at the source.
• Pigmentation — including post-inflammatory pigmentation and melasma. You can read more in our guide to treating pigmentation.
• Photoageing and fine lines — softening early wrinkles and sun damage.
• Uneven texture and tone — smoothing rough, dull or congested skin.

Tretinoin strengths in the UK: 0.025%, 0.05% and 0.1%

Tretinoin cream is available in several concentrations. Higher strengths are more potent but can be more irritating, so a clinician will recommend the right starting strength for your skin and concern. As an Obagi Ambassador Clinic, Dermoperfection supplies 100% authentic Obagi tretinoin in the following options:

• Obagi Tretinoin 0.025% — the gentlest cream, ideal for first-time users or more sensitive skin.
• Obagi Tretinoin 0.05% — a mid-strength cream for those who have built up tolerance.
• Obagi Tretinoin 0.1% — the strongest cream, suited to experienced users under clinical guidance.
• Obagi Tretinoin Gel 0.05% — a lighter gel formulation often preferred for oilier or combination skin.

Tretinoin cream vs gel

Both formulations contain the same active ingredient. Tretinoin cream tends to be more hydrating and is often better tolerated by dry or sensitive skin, while tretinoin gel has a lighter finish that many people with oilier skin prefer. Your clinician will help you choose the format and strength that suit your skin type and goals.

How to get tretinoin in the UK

Because tretinoin is prescription-only, you cannot legally buy it from a supermarket or high-street shop, and buying unregulated “tretinoin” online carries real safety risks. In the UK, tretinoin is accessed through a registered prescriber following a consultation and medical assessment. At Dermoperfection — an Obagi Ambassador Clinic in Birmingham — new customers complete a short medical form which our clinical team reviews before any tretinoin is dispensed, so we can confirm it is appropriate and safe for you. You can view the full Obagi range online.

How to use tretinoin

Tretinoin is powerful, so most people are advised to introduce it gradually:

• Start with a pea-sized amount 2–3 nights per week, building up frequency as your skin adjusts.
• Apply at night to clean, dry skin, and follow with a moisturiser.
• If you experience irritation, the “buffer” or “sandwich” method (moisturiser before and after) can help.
• Wear a daily broad-spectrum SPF — tretinoin increases sun sensitivity.

It is normal to experience a “retinisation” period of dryness, flaking or mild purging in the first few weeks as your skin adapts.

Side effects and who should avoid tretinoin

Common, usually temporary side effects include dryness, peeling, redness and increased sun sensitivity. Tretinoin should not be used during pregnancy or while breastfeeding, and is not suitable for everyone — which is exactly why a medical assessment is required before it is prescribed.

Tretinoin vs retinol: what’s the difference?

Retinol is a milder, over-the-counter precursor that the skin must convert before it becomes active, so results are slower and gentler. Tretinoin is already in its active form, making it considerably more potent — and the reason it is prescription-only. If you have used retinol without seeing the results you want, prescription tretinoin (with clinical supervision) may be the next step.

Frequently asked questions

Can you buy tretinoin over the counter in the UK?

No. Tretinoin is a prescription-only medicine in the UK and can only be supplied after a medical assessment by a registered prescriber.

How long does tretinoin take to work?

Most people start to see improvements in tone and texture within 6–12 weeks of consistent use, with continued improvement over several months.

Which tretinoin strength should I start with?

Many first-time users begin with 0.025% and build up under guidance. Your clinician will recommend the most appropriate starting strength for your skin.

Is tretinoin cream the same as retinol?

No — tretinoin is the prescription-strength, active form of vitamin A, whereas retinol is a milder over-the-counter ingredient that must first be converted by the skin.

Tretinoin is a prescription-only medicine and is supplied only after a medical assessment. To find out whether tretinoin is right for your skin, contact our clinical team or explore the Obagi range.
