Inside Out Reset: Dr Maryam Zamani’s Guide to Skin Longevity

Skin longevity is not about chasing quick fixes or reacting to trends. It is about supporting the skin in a way that allows it to function well, adapt to change and remain resilient over time.

To explore what truly makes a difference, Dr Maryam Zamani, founder of MZ SKIN, interviewed three respected experts across nutrition and longevity. The goal was simple: to gather clear, evidence-led insight into how skin health can be supported from the inside out, across collagen, radiance and midlife resilience. What emerged was a shared philosophy. There is no single product or shortcut that delivers skin longevity. Lasting results are cultivated through consistent daily rituals that support the skin internally, protect it externally and strengthen its ability to cope with stress over time.

This guide brings those insights together into a practical, easy-to-follow framework.

Why Skin Longevity Requires an Inside-Out Approach

Skin is not an isolated organ. Its appearance reflects internal ongoings of the body, from nutrition and gut health to sleep, stress and hormonal balance. When the body is under strain, the skin can be the first place it shows.

An inside-out skincare approach recognises that topical products work best when combined with holistic health. Nutrition, lifestyle habits and targeted supplementation enhance the performance of active ingredients and can strengthen the skin barrier, improving long-term resilience.

Rather than focusing on short-term results, skin longevity prioritises structure, function and consistency.

The Three Pillars of Skin Longevity

  1. Collagen and Skin Structure: Supporting Firmness and Elasticity

Collagen is the protein responsible for the skin’s firmness, elasticity and structural support. As we age, collagen production naturally declines, often from our mid-thirties, leading to visible changes like fine lines, loss of firmness and a dullness to the skin.

This decline is accelerated by everyday lifestyle and environmental factors, including:

  • UV exposure

  • Stress and poor sleep

  • Sugar and alcohol

  • Smoking

  • Pollution and oxidative stress

Supporting collagen effectively requires a dual approach. Internally, collagen peptides can provide the building blocks that encourage the body’s own collagen production, particularly when paired with adequate protein intake and vitamin C. Topical peptides can also play a role in supporting skin structure. Formulations designed to reinforce the skin barrier and stimulate fibroblast activity can help improve firmness and texture over time. At MZ SKIN, peptide-led formulas are designed to support collagen from the outside in, complementing internal support such as nutrition and supplementation.

Collagen is not a quick fix. It is an accumulative investment. One that depends on quality formulations and consistent use over time.

  1.  Radiance & Brightness: Restoring Balance After Stress and Disruption

Radiance and brightness are often the first things to fade when the skin barrier is compromised. Periods of stress, overindulgence, disrupted sleep, or travel can slow cell turnover and leave skin looking dull and dehydrated.

Rather than aggressive treatments or extreme detoxes, radiance is best restored through gentle, consistent support. From a topical perspective, this includes hydration, antioxidant replenishment and controlled exfoliation to encourage renewal without stripping the skin.

Vitamin C plays a central role here. Helping to neutralise free radicals, support collagen production and improve overall brightness. When used consistently, a stabilised vitamin C serum can help protect the skin during the day while enhancing clarity and luminosity over time. This is why vitamin C is a cornerstone of the MZ SKIN three-step ritual.

From within, glow is closely linked to daily nutrition:

  • Protein with every meal to support repair and regeneration

  • Fibre-rich carbohydrates to support digestion and the gut–skin connection

  • Essential fatty acids to maintain barrier function

  • Adequate hydration throughout the day

When internal nourishment aligns with topical skincare, the skin responds with improved clarity, tone and brightness.

  1. Midlife Skin Resilience: Longevity Through Consistent Support

Midlife brings hormonal shifts that can impact skin elasticity, hydration and firmness. At the same time, poor sleep, chronic stress and environmental exposure can accelerate visible signs of ageing, particularly around the eyes, where skin is thinner and more reactive.

Longevity-focused skincare at this stage is not about restriction or drastic change. It is about sustainably supporting the skin and body. 

Key foundations include:

  • Prioritising sleep quality

  • Managing stress, which shows on the skin faster than many realise

  • Maintaining regular meals and hydration

  • Strength training and daily movement

  • Targeted supplementation based on individual needs

  • Medical guidance where appropriate

Nutritionally, antioxidant-rich foods, essential fatty acids and collagen-supporting nutrients help counter oxidative stress and support elasticity. Topically, regenerative skincare that strengthens the barrier and supports collagen synthesis becomes increasingly important.

There is no single solution for midlife skin, but when the basics are done well and consistently, the skin becomes more resilient and balanced over time.

The Inside Out Reset: Daily Rituals for Long-Term Skin Health

Skin longevity is built through repeatable daily habits rather than complicated routines.

Daily Nutrition Habits That Support Skin Longevity

  • Protein with every meal (including snacks where possible)

  • Fibre-rich vegetables, fruits and wholegrains

  • Hydration throughout the day (herbal teas included)

  • Targeted supplementation such as collagen peptides, antioxidants and essential fatty acids

Topical Skincare Rituals That Strengthen the Skin Barrier

These rituals do not need to be perfect. They simply need to be consistent.

Common Myths About Ageing, Collagen and Skin Health

  • Collagen does not work overnight; results come from sustained use

  • Extreme detoxes do not create radiance and often increase stress

  • There is no single “magic” supplement for ageing

  • More products do not equal better skin - targeted routines are more effective

The most important takeaway from Dr Maryam Zamani’s expert conversations is reassuring: Skin longevity is built quietly. It comes from small, evidence-based actions repeated daily, not dramatic overhauls.

When nutrition, lifestyle and skincare work together, the skin becomes stronger, calmer and more resilient over time. Longevity is not a moment or a trend; it is a lifestyle that supports the skin at every stage.
