Most customers begin to notice improvements within a few weeks, but the exact timing depends on your skin type, the products you are using and how consistently you use them.

Here is a general guide:

After 1–2 weeks

You may notice your skin feels smoother, more comfortable
and better hydrated. Makeup often sits more evenly and the skin may look
fresher.

After 4–6 weeks

This is when visible changes usually become more noticeable.

You may see improvements in:

• Texture and clarity
• Lines and wrinkles
• Radiance and evenness
• Comfort and resilience

After 8–12 weeks

Deeper, longer-term changes begin to appear as the skin
completes several renewal cycles.

This is when you may notice:

• Reduction in pigmentation or sun damage
• Improved firmness
• More refined pores
• A healthier, more even complexion overall

Long-term use gives the best results

Regentiv products are designed to support the skin
continuously, so the benefits build over time. Many customers stay with the
same preparations for years because the results keep improving with consistent
use.

In short: some results can appear quickly, but the most meaningful improvements develop gradually — and continue to strengthen withregular use.

Because Regentiv offers something different — specialist formulations developed with Harley Street expertise, trusted for more than 25 years, and refined through real customer feedback, not trends.

In a world full of skincare brands, we remain intentionally focused and specialist. Here is what makes Regentiv truly distinct:

1. Expertise you can trust

Regentiv was created by a Harley Street skin specialist, drawing on decades of clinical insight. Every preparation is developed with a deep understanding of skin behaviour, age-related changes and real-worldconcerns.

2. Formulated for results, not trends

Our products address meaningful skin needs — ageing, pigmentation, sensitivity, post-procedure care and overall skin health. We do not follow fads. We focus on what genuinely works and what customers return to, year after year.

3. High-quality ingredients, thoughtfully balanced

We combine proven actives with soothing botanicals to deliver results without overwhelming the skin. Each product is designed to be effective, comfortable and suitable for long-term use.

4. Direct-to-customer care

We are not a mass-market retail brand. By offering our products directly, we maintain quality, listen carefully to feedback, and continually refine our formulations. This is why we have loyal customers who never want to use anything else.

5. Trusted for more than 25 years

Our reputation has grown quietly through recommendation, not
advertising. Customers stay with Regentiv because the products work and because the experience feels personal, expert and sincere.

In short: choose Regentiv if you want specialist skincare created with integrity, expertise and care — not hype.

Yes — many customers choose to use Regentiv exclusively, and you can absolutely build a complete routine with our preparations alone.

Every product has been developed to work harmoniously with the others, creating a balanced, effective skincare system that supports your skin morning and night.

Why a full Regentiv routine works so well

• Formulations are designed to complement each other
  The textures, active levels and ingredient combinations are intentionally balanced so your skin receives support without irritation or overload.
• You cover every step of a specialist routine
  From cleansing and calming to renewing, brightening, firming and protecting — Regentiv offers everything your skin needs for long-term health.
• Consistency gives the best results
  Using preparations from the same specialist system allows your skin to respond more predictably and effectively, especially over time.
• Perfect for sensitive or reactive skin
  For customers who react to mixing too many brands or conflicting ingredients, staying within a single, carefully designed range can make a noticeable difference in comfort.

But it is entirely your choice

You can use Regentiv exclusively, or blend our preparations with others you already enjoy. Both approaches work — the key is choosing what feels right for your skin.

In short: yes, a full Regentiv routine can meet all your skin’s needs — and many customers prefer it — but you are always free to personalise your routine.

Yes — our products are designed to integrate smoothly into your routine, and many customers successfully combine Regentiv with other
trusted skincare brands.

A few guidelines to ensure the best results:

• Choose the Regentiv product that addresses your primary concern (texture, tone, firmness, sensitivity).
• Introduce it gradually if you are already using potent active ingredients from other brands (such as strong retinoids or exfoliants).
• Ensure your routine remains balanced — cleanser → treatment (serum) → moisturiser→ broad-spectrum sunscreen (day) — and avoid layering too many strong actives at once.
• If you are combining brands that both use different vitamin A derivatives, acids or actives, consider using them on alternate nights or for different skin zones.
• If your skin is very sensitive or you are using prescription treatments, we recommend consulting a skin professional before combining multiple performance-level products.

In summary: yes, you can absolutely mix Regentiv with other brands — just do so carefully, monitor how your skin feels, and prioritise consistency and skin comfort.

Regentiv is not available in retail stores because we choose to keep our formulations specialist, focused and directly supported by our Harley Street expertise.

For over 25 years, our products have been recommended through personal relationships, professional skin consultations and word-of-mouth — not mass retail. By offering our preparations directly, we can:

• Maintain the high quality of every formula
• Keep our ingredients uncompromised
• Listen to feedback and continually refine and improve our products
• Provide genuine guidance, rather than relying on in-store sales methods
• Offer products that are clinically focused, not commercially diluted

This approach allows us to remain true to what makes Regentiv different: specialist skincare, trusted by generations, grounded in expertise — not retail shelves.

We understand why samples are popular, but we choose not to offer them because they do not give a true or fair experience of how our specialist formulations work.

Our products are designed for meaningful, long-term results — and very small sample sizes rarely allow enough time or consistency for customers to see the real benefits.

Here is why we have chosen this approach:

1. Skincare needs time, not a single-use sachet

Most Regentiv preparations take several weeks to reveal their full effect.

A tiny amount used once or twice can lead to the wrong impression, especially
for concerns like ageing, pigmentation or sensitivity.

2. Specialist formulations require specialist packaging

Many of our preparations use protective airless pumps to
maintain stability and effectiveness.

Samples often cannot replicate this environment, which risks compromising the formula.

3. We prefer to invest in product quality, not disposable packaging

Sample sachets create significant waste for very little product.

We choose to focus on high-quality, long-lasting packaging that reflects our
values of refinement and responsibility.

4. We guide customers personally instead

Rather than offering a one-use sample, we provide thoughtful, individual recommendations so you can choose the preparation that suits your skin best from the start.

In short: samples rarely reflect how Regentiv truly performs, so we prioritise full-size preparations, proper packaging, and personalised guidance instead.

For decades, our customers have discovered us in the most meaningful way possible: through personal referrals from friends, family and Harley Street patients.

Because of this:

• We have never relied on large marketing budgets or influencer partnerships
• Most of our customers have stayed with us for many years and simply buy what they love
• We focused on formulation quality and long-term results, rather than collecting online reviews
• Our social media presence has always been understated, reflecting the discreet way people have traditionally found us

Now, as more customers choose to shop online, we are inviting people to share their experiences so others can benefit from their stories too. But our foundation remains the same: quiet expertise, loyal customers, and trusted formulations that speak for themselves — whether or not we shout about them online.

e use Retinyl Palmitate because it offers the proven benefits of vitamin A in a way that is gentle, stable and suitable for daily use — including during the day when supported by SPF.

Not all retinoids are the same. Stronger forms (like Retinol or prescription-strength retinoids) can be highly effective but are also more likely to cause irritation, redness and peeling — especially for sensitive or
mature skin.

Retinyl Palmitate is different:

• It is the most skin-compatible form of vitamin A
• It delivers visible smoothing and renewal with a lower risk of irritation
• It is more stable in formulations, helping to maintain effectiveness over time
• It pairs beautifully with hydrating and protective ingredients
• It is suitable for long-term, everyday use — which aligns with how Regentiv customers prefer to care for their skin

For Regentiv, effectiveness must always be balanced with comfort and consistency. Retinyl Palmitate allows us to support collagen, improve texture and encourage healthy renewal without overwhelming the skin.

In short: we choose the form of vitamin A that works for real people, every day — not just in theory.

Yes — Retinyl Palmitate can be used safely in a daytime moisturiser when it is expertly formulated and supported by broad-spectrum sun protection.

Enhance & Protect has been developed with this in mind. Retinyl Palmitate is a gentler vitamin A derivative that helps to support collagen, smooth texture and encourage healthy renewal without the intensity of prescription vitamin A or stronger retinoids.

In Regentiv formulations:

• We use measured, skin-supportive levels that are suitable for daytime use.
• The ingredient is paired with SPF 30, antioxidant vitamins and hydrating ingredients to help keep the skin comfortable and protected.
• It offers the benefits of vitamin A with a lower likelihood of sensitivity, making it appropriate for most skin types.

For anyone with very sensitive skin, we recommend introducing any vitamin A product gradually — but as formulated in Enhance & Protect, Retinyl Palmitate is entirely appropriate for daytime use.

Because different skin types — and different skin moments — need different levels of care.

At Regentiv, cleansing is not a simple “one size fits all” step. It is the foundation of every routine, and the right cleanser can make a noticeable difference to comfort, clarity and overall skin health.

We offer several cleansers because:

• Skin is not static. It changes with age, seasons, hormones, lifestyle and sensitivity.
• Some customers prefer a lighter, refreshing cleanse, while others need something more soothing or conditioning.
• Certain skin concerns — such as congestion, sensitivity or dryness — respond better to specific textures and ingredients.
• Different times of day call for different approaches (for example, a gentle morning cleanse vs. a deeper evening cleanse to remove makeup and impurities).

Each Regentiv cleanser has been formulated to solve a distinct need:

• Something for sensitive and reactive skin
• Something for daily comfort and hydration
• Something for clarity and gentle exfoliation
• Something for thorough makeup removal without drying

Rather than creating one universal product that compromises somewhere, we prefer to offer a small, specialist range — each done properly, each effective in its own right.

It means customers can choose the cleanser that feels best for their skin, today and as it evolves over time.
