Our skin is not only the largest organ of our body but also a remarkable and complex system that plays a crucial role in protecting and regulating our internal environment.

Skin, consisting of multiple layers, serves as a barrier against external threats, such as harmful UV rays, pollutants, and microorganisms. It acts as a shield, preventing dehydration and maintaining our body temperature. But there's more to skin than just its protective function.

In addition to its physical properties, skin is a reflection of our overall health and wellbeing. It reflects our lifestyle, habits, and even our emotions. From its texture and tone to its resilience and radiance, our skin reveals a lot of information.

Our skin is a complex organ composed of multiple layers and structures:

  • Epidermis: This is the outermost layer of the skin and acts as a protective barrier against external factors. It consists mainly of dead skin cells called keratinocytes. The epidermis also contains melanocytes, which produce the pigment melanin responsible for skin colour.
  • Dermis: Below the epidermis is the dermis, a thicker layer that contains various components including collagen, elastin fibres, blood vessels, and nerves. Collagen provides structural support and elasticity, while elastin fibres allow the skin to stretch and recoil. Blood vessels supply nutrients and oxygen to the skin cells.
  • Subcutaneous tissue: This is the deepest layer of the skin and primarily consists of fat cells (adipocytes) that provide insulation and padding.

    Science Behind Skin Ageing

    Ageing skin is a natural part of the human experience, a process that we all go through as we journey through life. As the years pass, our skin undergoes changes that can affect its appearance, texture, and overall vitality. Understanding the factors that contribute to ageing skin can help us make informed choices about skincare routines and lifestyle habits.

    So, let's explore 3 main types of skin ageing:

    • Intrinsic ageing: This refers to the genetic and physiological changes that occur naturally over time. As we age, the production of collagen and elastin decreases, leading to a loss of skin elasticity and firmness. Skin cell turnover also slows down, resulting in a duller complexion.
    • Extrinsic ageing: External factors can accelerate the ageing process of the skin. The most significant external factor is sun exposure. Ultraviolet (UV) radiation from the sun damages collagen and elastin fibres, leading to wrinkles, age spots, and uneven skin tone. Other external factors that contribute to ageing include smoking, pollution, poor nutrition, and repetitive facial expressions.
    • Free radicals: These are unstable molecules that can cause damage to skin cells and accelerate the ageing process. Free radicals are generated by factors such as sun exposure, pollution, and smoking. Antioxidants help neutralise free radicals and protect the skin.

    Factors That Cause Our Skin To Age

    • Cellular senescence
    With age, our skin cells undergo a process called cellular senescence, where they lose their ability to divide and repair themselves effectively. This leads to a decrease in cell turnover and regeneration, resulting in a thinner epidermis and slower wound healing.
    • Collagen and elastin degradation
    Collagen and elastin are proteins found in the dermis that provide structural support and elasticity to the skin. Over time, enzymes called matrix metalloproteinases (MMPs) increase, causing the breakdown of collagen and elastin fibres. This leads to the formation of wrinkles, sagging skin, and loss of elasticity.
    • Oxidative stress
    Reactive oxygen species (ROS), also known as free radicals, are generated in our cells as byproducts of metabolism. Excessive production of ROS and a decrease in antioxidant defense mechanisms can result in oxidative stress. This oxidative stress damages DNA, proteins, and lipids, accelerating the ageing process and contributing to wrinkles, age spots, and uneven skin tone.
    • Glycation
    Glycation is a chemical reaction that occurs between sugar molecules and proteins or lipids in our skin. This process forms advanced glycation end products (AGEs), which can accumulate and interfere with the normal functioning of proteins, including collagen and elastin. The presence of AGEs contributes to the loss of skin elasticity, firmness, and the formation of wrinkles.
    • Inflammation

    Chronic low-grade inflammation, known as inflammageing, is associated with ageing skin. Inflammatory mediators, such as cytokines and prostaglandins, can disrupt the skin's normal function and contribute to skin ageing. Inflammation can be triggered by various factors, including UV radiation, environmental pollutants, and lifestyle choices.

    How To Naturally Slow Down Skin Ageing

    There are several natural ways to help slow down the ageing process of the skin. While aging is a natural and inevitable process, these practices can help maintain healthier and more youthful-looking skin:

    • Protect your skin from the sun

    Sun exposure is one of the primary causes of skin aging. Protect your skin by wearing natural sunscreen with a high SPF, seeking shade during peak sun hours, and wearing protective clothing, such as hats and sunglasses.

    Natural SPF creams or lotions typically contain ingredients derived from natural sources, such as plant extracts and oils, that offer sun protection. These products often use mineral-based ingredients like zinc oxide or titanium dioxide, which work by sitting on top of the skin and physically blocking or reflecting UV rays. Natural SPF creams are generally considered safer for the skin and the environment, as they don't contain potentially harmful chemicals.

    On the other hand, unnatural SPF creams or lotions often contain synthetic or chemical-based ingredients, such as oxybenzone, avobenzone, or octinoxate. These chemicals work by absorbing UV rays and converting them into heat, thereby reducing their impact on the skin. While synthetic SPF products can be effective in sun protection, some people may experience skin irritation or other adverse reactions due to the presence of these chemicals.

    • Maintain a healthy diet
    A well-balanced diet rich in antioxidants, vitamins, and minerals can support overall skin health.By including a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats in your diet, you can provide your skin with the essential nutrients it needs to stay nourished and resilient. These nutrients help protect against oxidative stress, promote collagen production, and maintain a youthful complexion. Remember, nourishing your skin from the inside out is just as important as caring for it externally.
    • Stay hydrated
    Good hydration is essential for maintaining skin elasticity and suppleness. Drink plenty of water throughout the day to keep your skin hydrated from within. Hydrated skin is less prone to dryness, fine lines, and wrinkles, giving it a smoother and more youthful appearance. Remember, when it comes to skincare, nourishing your skin externally with natural moisturisers and face oils should be complemented by maintaining proper hydration levels internally through regular water drinking. Discover the benefits our founder has found from drinking warm water with lemon every morning:


    • Get enough sleep
    Quality sleep allows your body to repair and regenerate cells, including skin cells. Aim for 7-8 hours of sleep each night to support healthy skin. Lack of sleep can lead to increased stress levels, which can contribute to premature skin ageing. By having restful sleep, you give your skin the opportunity to repair itself, resulting in a more vibrant and youthful complexion. Remember, a good night's sleep is not only crucial for your overall wellbeing but also plays a vital role in maintaining healthy, radiant skin.
    • Practice stress management
    Chronic stress can have detrimental effects on the skin, leading to increased inflammation, collagen breakdown, and accelerated ageing. Practicing stress-reducing activities such as meditation, deep breathing exercises, yoga, or pursuing hobbies can help you relax and unwind and significantly benefit your skin. These practices promote a sense of calm and balance, reducing stress levels and improving overall skin health. By managing stress effectively, you can minimise the impact of stress on your skin, helping to maintain its youthful appearance for longer.
    • Avoid smoking and limit alcohol consumption
    Smoking damages collagen and elastin fibres in the skin, leading to premature ageing. Excessive alcohol consumption can dehydrate the skin and contribute to inflammation and oxidative stress. By avoiding smoking and moderating your alcohol intake, you can protect your skin from the harmful effects of these substances. This decision will not only benefit your skin's appearance but also promote overall health and wellbeing. Remember, making these lifestyle choices can have a significant impact on the health and vitality of your skin, helping you maintain a youthful and radiant complexion as you age.
    • Cleanse and moisturise your skin

    Maintaining a regular skincare routine that includes gentle cleansing and moisturising is essential for naturally slowing down skin ageing. Cleansing helps remove dirt, impurities, and excess oil that can accumulate on the skin's surface, allowing it to breathe and function optimally. After cleansing, don't forget to moisturise. Use LIZA VETA Miracle Facial Oil to help replenish and lock in moisture, keeping your skin hydrated and nourished. Our face oil has plenty of Rosehip Oil in it that is known to help combat the signs of skin ageing and improve the overall appearance and vitality of your skin, promoting a more youthful and radiant complexion.

    • Use natural skincare products

    Using natural skincare products is essential for supporting ageing skin. Natural skincare products are made with gentle, plant-based ingredients that are less likely to irritate or harm the skin. They avoid harsh chemicals and synthetic additives, which can disrupt the skin's balance and contribute to skin ageing. Natural skincare products also contain beneficial botanical extracts, oils, and plant-based actives that provide vitamins, antioxidants, and essential fatty acids. These nutrients nourish and support the health of ageing skin. Conventional skincare products often contain harmful substances like parabens, sulfates, and synthetic fragrances. These ingredients can cause skin irritation, allergies, and hormonal disruptions. Natural skincare products avoid these potentially harmful substances.

    • Engage in regular physical activity

    Exercise improves blood circulation, which can promote healthy skin. Exercise increases blood flow throughout the body, including the skin. This improved circulation delivers oxygen and nutrients to the skin cells, promoting a healthy and vibrant complexion.

    Regular physical activity helps reduce stress levels by releasing endorphins, also known as "feel-good" hormones. High stress levels can contribute to skin ageing by increasing inflammation and oxidative stress. By managing stress through exercise, you can support healthier-looking skin.

    Sweating during exercise helps remove toxins from the body, including those that can clog pores and contribute to skin issues. This natural detoxification process can leave your skin looking clearer and more radiant.

    Exercise can also help improve muscle tone and increase collagen production, which contributes to skin elasticity. This can help reduce the appearance of fine lines and wrinkles, giving your skin a more youthful and firm appearance.

    Overall Wellbeing: Regular physical activity is essential for maintaining overall wellbeing. When you feel good, it reflects in your skin. Exercise promotes a sense of vitality and boosts your self-confidence, which can positively impact your skin health.

    • Practice good skincare habits

    Avoid excessive touching, tugging, or rubbing of your skin, as this can cause irritation and accelerate the ageing process. Treat your skin with care and handle it gently during cleansing, applying products, and removing makeup.

    Dry environments can dehydrate the skin, leading to dryness and potential signs of ageing. Consider using a humidifier in your home or workspace to add moisture to the air and help keep your skin hydrated.

    While hot showers or baths may feel relaxing, they can strip the skin of its natural oils, leading to dryness and irritation. Opt for lukewarm water when cleansing your face and body to maintain the skin's moisture balance.

    Protect your skin from harmful environmental factors that can contribute to skin ageing, such as UV radiation and pollution. Apply a broad-spectrum natural sunscreen with at least SPF 30 daily, even on cloudy days, and consider using protective clothing and accessories like hats and sunglasses.

    Always remove your makeup before going to bed to allow your skin to breathe and regenerate overnight. Leaving makeup on can clog pores, leading to breakouts and dull-looking skin.
