Ageing is an inevitable process, one that is influenced by both intrinsic factors, such as genetics, and extrinsic factors, like environmental exposure and lifestyle choices. Over time, our skin starts to show visible signs of ageing, such as wrinkles, fine lines, sagging, age spots, and uneven skin tone. As people become more conscious of maintaining a youthful appearance, the demand for effective anti-ageing treatments continues to grow. The question many have is: how do these treatments work to reduce the visible signs of ageing? Here we will dive deep into the science behind ageing and explore how anti-ageing treatment combat the signs of time.
The Biology of Ageing Skin
Before exploring anti-ageing treatment, it’s essential to understand how and why skin ages. Ageing skin is a product of several factors:
- Decreased Collagen Production: Collagen, a protein that gives the skin its structure and elasticity, diminishes with age. Starting in your 20s, the body produces about 1% less collagen each year. Less collagen results in thinner, less elastic skin, which leads to the formation of wrinkles and sagging.
- Loss of Elastin: Elastin fibres allow the skin to stretch and return to its normal shape. Similar to collagen, the production of elastin decreases over time, contributing to loose, sagging skin.
- Reduced Skin Cell Turnover: Younger skin renews itself approximately every 28 days. As we age, this process slows down, causing dead cells to accumulate on the surface of the skin, making it appear dull, uneven, and more prone to fine lines.
- Oxidative Stress: Free radicals from environmental factors like UV radiation, pollution, and smoking cause oxidative stress in the skin, breaking down collagen and elastin. Over time, this leads to wrinkles, loss of firmness, and hyperpigmentation.
- Reduction in Hydration: Ageing skin also produces fewer natural oils, resulting in dryness and a loss of the moisture barrier. This accelerates the appearance of fine lines and sagging.
Anti-Ageing Treatments: How They Work
There are a variety of anti-ageing treatments available today, ranging from non-invasive skincare products to more advanced cosmetic procedures. Each anti-ageing treatment method works differently to target the root causes of ageing, aiming to restore the skin’s youthful appearance. Below, we’ll explore the most common types of anti-ageing treatments and how they work to combat ageing at a cellular level.
1. Topical Treatments
Topical treatments are typically the first line of defence against ageing skin. They are widely accessible and offer less invasive options compared to procedures. The most effective topical treatments often include active ingredients designed to stimulate collagen production, exfoliate the skin, or protect against environmental damage.
a. Retinoids (Vitamin A Derivatives)
Retinoids, including prescription-strength retinoic acid and over-the-counter retinol, are some of the most well-researched and effective anti-ageing ingredients. Retinoids work by accelerating skin cell turnover and stimulating collagen production. By doing so, they help to reduce fine lines, even out skin tone, and improve skin texture.
Mechanism of Action: Retinoids bind to retinoic acid receptors in the skin, promoting the growth of new skin cells and reducing the breakdown of collagen. Over time, they improve the thickness of the skin’s epidermis (outer layer) and promote dermal collagen production, leading to firmer, smoother skin.
b. Vitamin C (Ascorbic Acid)
Vitamin C is a potent antioxidant that neutralises free radicals, reducing oxidative stress and preventing damage to collagen and elastin fibres. In addition to its protective properties, Vitamin C promotes collagen synthesis and reduces hyperpigmentation, leading to a brighter, more even complexion.
Mechanism of Action: Vitamin C works by stabilising collagen molecules and enhancing the skin’s repair mechanisms. It also inhibits tyrosinase, an enzyme involved in melanin production, thereby lightening age spots and preventing future pigmentation.
c. Peptides
Peptides are short chains of amino acids that serve as building blocks for proteins like collagen and elastin. In skincare, peptides stimulate the skin to produce more collagen, leading to firmer, plumper skin over time.
Mechanism of Action: Peptides mimic the skin’s natural healing processes by signaling to the skin that it needs to produce more collagen and elastin. By increasing collagen levels, peptides help reduce the appearance of fine lines and improve skin elasticity.
d. Alpha Hydroxy Acids (AHAs)
AHAs, such as glycolic acid and lactic acid, are exfoliating agents that remove dead skin cells from the surface of the skin. By promoting exfoliation, AHAs improve skin texture, reduce the appearance of fine lines, and help brighten the complexion.
Mechanism of Action: AHAs dissolve the bonds that hold dead skin cells together, facilitating their removal. This encourages the growth of new skin cells and improves the overall texture of the skin. By smoothing out the skin’s surface, AHAs can also enhance the penetration of other anti-ageing ingredients like retinoids and peptides.
2. Injectable Treatments
For individuals seeking more immediate results, injectable treatments offer a non-surgical way to reduce the appearance of wrinkles and restore lost volume. These treatments, administered by professionals, target specific areas of concern such as forehead wrinkles, crow’s feet, or volume loss in the cheeks.
a. Botulinum Toxin (Botox)
Botox is one of the most popular anti-ageing treatments. It works by temporarily paralysing muscles responsible for dynamic wrinkles, which are caused by repetitive facial movements like frowning or squinting.
Mechanism of Action: Botox is a neurotoxin that blocks the release of acetylcholine, a neurotransmitter responsible for muscle contraction. By relaxing the facial muscles, Botox smooths out dynamic wrinkles and prevents new lines from forming. While Botox doesn’t directly stimulate collagen production, it gives the skin a smoother, more youthful appearance.
b. Dermal Fillers
Dermal fillers, such as hyaluronic acid, are injectables used to restore volume to areas of the face that have lost fullness due to ageing. They are commonly used to plump the lips, smooth nasolabial folds, and fill in hollow areas under the eyes.
Mechanism of Action: Hyaluronic acid fillers work by attracting water to the injected area, creating volume and smoothing out wrinkles. Hyaluronic acid also stimulates collagen production, offering long-term benefits. Results are immediate, but depending on the filler used, they typically last between six months to two years.
3. Laser and Light-Based Therapies
Laser treatments are among the most effective non-invasive procedures for addressing a variety of ageing concerns, including wrinkles, sun damage, and skin laxity. These treatments use focused light energy to target different layers of the skin, promoting collagen production and reducing pigmentation.
a. Fractional Laser Resurfacing
Fractional laser treatments create controlled micro-injuries to the skin’s surface, triggering the body’s natural healing response. This promotes collagen production and improves skin texture.
Mechanism of Action: Fractional lasers deliver heat to the skin in tiny, evenly spaced columns. The surrounding untreated skin helps with faster healing, and the laser’s energy stimulates collagen remodeling in the deeper layers of the skin. This leads to tighter, smoother skin with fewer wrinkles and pigmentation issues.
b. Intense Pulsed Light (IPL)
IPL is a broad-spectrum light treatment that targets pigmentation, redness, and fine lines. It is often used to treat sun damage, age spots, and uneven skin tone.
Mechanism of Action: IPL works by delivering pulses of light that are absorbed by the skin’s pigmented cells, breaking down excess melanin and reducing redness. Over time, this leads to a more even skin tone. IPL also stimulates collagen production, improving skin texture and reducing fine lines.
4. Radiofrequency (RF) Treatments
Radiofrequency treatments use energy to heat the deeper layers of the skin, encouraging collagen production without damaging the surface. This leads to tighter, firmer skin over time.
Mechanism of Action: RF treatments target the dermal layer of the skin, delivering controlled heat that stimulates collagen synthesis. The result is improved skin tightness and a reduction in fine lines and sagging skin. RF treatments are often combined with microneedling for enhanced results.
5. Chemical Peels
Chemical peels are another popular anti-ageing treatment that involves applying a chemical solution to the skin, causing it to exfoliate and eventually peel off. The new skin underneath is smoother and less wrinkled.
Mechanism of Action: Chemical peels use acids such as glycolic, salicylic, or trichloroacetic acid to remove the top layers of skin. This stimulates the growth of new skin cells and collagen, resulting in smoother skin, improved tone, and fewer fine lines.
Conclusion
Anti-ageing treatments work by addressing the core mechanisms of skin ageing—decreasing collagen production, reduced cell turnover, and environmental damage. From topical treatments like retinoids and Vitamin C that stimulate collagen and protect against oxidative damage, to injectables like Botox and dermal fillers that smooth wrinkles and restore volume, modern anti-ageing options offer targeted, effective results. Laser therapies, radio frequency, and chemical peels also play crucial roles in rejuvenating the skin by stimulating its natural repair processes. By understanding how each treatment works, individuals can choose the best method to achieve their anti-ageing goals, maintain a youthful appearance, and enjoy healthy, vibrant skin for years to come.
