As night falls, our skin begins one of its most important processes: regeneration.
While we sleep, our bodies work to repair and rejuvenate themselves, and this is particularly true of the dermis. Understanding how to harness and enhance this natural nighttime healing process can make a significant difference to the appearance and health of our skin.
The Science of Skin Regeneration
Our skin is a dynamic organ that continuously regenerates itself according to a circadian rhythm, a natural 24-hour cycle that regulates various biological processes.
During the day, the skin is in defence mode, protecting itself from environmental stressors such as UV rays, pollution, and harsh weather.
At night, however, its focus shifts from defence to repair. Cellular regeneration peaks at night, typically between 10 pm and 2 am. During this time, skin cell turnover increases, allowing dead cells to be shed and new cells to grow, DNA repair is at its highest, and our skin’s natural antioxidant levels are replenished. This is why a good night's sleep is often referred to as ‘beauty sleep’ – it gives our skin a chance to heal and repair itself.
In addition, skin is more permeable at night, which means it’s more receptive to the active ingredients in our skincare products. This increased permeability makes night time the ideal moment to use formulations that target specific concerns such as ageing, dehydration, laxity and hyperpigmentation.
How to Help Skin Regenerate at Night
Here are some key steps to consider in your skincare routine:
1. Cleanse effectively
Before our skin can repair itself, it needs to be free of impurities such as make-up, dirt and excess oil. Cleansing thoroughly at night is essential to allow our skin to breathe and absorb the active ingredients in our products.
Choose an oil-based, non-aggressive cleanser, that respects your skin's natural barrier, which plays a crucial role in protecting against irritants and locking in moisture. Cleansing with harsh detergents can strip away essential lipids, leading to a weakened stratum corneum and impaired regeneration.
2. Hydrate and Lock-In Moisture
At night, our skin tends to lose more water due to increased trans-epidermal water loss (TEWL). This makes hydration a key component of any nighttime routine.
Products containing hyaluronic acid are particularly beneficial because they attract and retain moisture, helping to prevent dehydration.
Look for formulas that offer hyaluronic acid in multiple molecular weights to ensure deep penetration into skin layers, such as The Radiance Booster multifunctional serum.
3. Repairing and Anti-Ageing Ingredients
As we age, our skin’s ability to regenerate slows down. Incorporating ingredients that promote cell turnover and repair can help combat this natural decline.
Retinol is well known for its ability to accelerate skin cell turnover and stimulate collagen production. However, it can be irritating to some skin types, so much so that the European Cosmetics Regulation has reduced its maximum level in facial skincare products to 0.3%.
An alternative approach is to use solutions containing Niacinamide, a form of Vitamin B3, which not only supports barrier function by boosting ceramide production, but also works against free radical damage and signs of ageing, enhancing the skin's repair mechanisms without causing irritation.
Another powerful ingredient to consider is Centella asiatica, commonly known as Cica. This plant extract is renowned for its anti-inflammatory and healing properties, making it ideal for soothing and repairing skin that has been exposed to environmental stressors during the day.
And finally, peptides. By stimulating collagen production, peptides help maintain firmness and elasticity, reducing the appearance of wrinkles over time.
4. The Role of Antioxidants
Antioxidants neutralise free radicals, which can cause cell damage and accelerate ageing. Incorporating antioxidant-rich products into our day and night routines can help repair daytime damage and protect our skin from future harm.
Ingredients such as dragon’s blood, a resin known for its healing and antioxidant properties, can be particularly effective. This ingredient helps to calm inflammation, increase collagen production and protect the skin from oxidative stress, which is essential for maintaining a youthful, radiant complexion.
5. Simplicity Is Key
When it comes to skincare, more isn’t always better.
Overloading our dermis with too many products can cause irritation and overwhelm the skin’s natural repair processes. A multifunctional approach - using products that address multiple skin concerns at once - can be highly effective.
This not only simplifies our routine, but also ensures that our skin is receiving a balanced and well-rounded treatment, without unnecessary layering of products whose active ingredients may not work perfectly together.
The Role of Sleep in Skin Regeneration
Aside from the formulations we use, one of the most important factors in overnight skin regeneration is sleep itself.
During deep sleep, our bodies release more growth hormones, which help repair tissue and regenerate cells. Lack of sleep can disrupt this process, leading to increased levels of stress hormones such as cortisol, which can compromise the skin’s barrier function and slow down repair mechanisms.
Aim for 7-9 hours of uninterrupted sleep each night and try to establish a regular sleep schedule. Implementing a calming pre-sleep routine - such as reducing screen time, practicing relaxation techniques or using de-stressing essential oils - can also improve sleep quality and, in turn, our skin’s ability to regenerate.

Sustainability and Skincare: A Planet-friendly Perspective
Incorporating sustainability into our skincare routine doesn’t have to mean compromising on effectiveness. In fact, using multifunctional products that address multiple concerns at once can simplify our routine, prevent stress on the skin and reduce waste.
Pherve multifunctional serum The Radiance Booster, for example, is designed to work both day and night, to provide deep hydration, boost collagen and elastin production, and defend and repair the skin barrier.
By choosing multifunctional formulations that concentrate high-quality natural ingredients and actives, you can achieve better results with fewer products. This not only benefits your skin, but also reduces the environmental impact associated with the recycling and overproduction of beauty products.
Embrace Your Nighttime Ritual
Consistency and simplicity are the keys to a more radiant youthful complexion and effective skincare. Stick to a routine that works for you, prioritise ingredients that meet your skin’s needs and, most importantly, get enough restful sleep.
By following these steps, you’ll be well on your way to unlocking the full potential of your skin’s nighttime regeneration.
