Ageing skin is no longer viewed purely through the lens of appearance, the focus has expanded to how the skin functions over time. Due to the natural aging process and exposure to external elements such as sun, pollution and our daily habits, our skin becomes thinner, less resilient and unable to defend itself against external elements that contribute to the aging process. The changes that occur in our skin over time because of these internal and external factors manifest through fine lines, areas of roughness, dryness, and a noticeable decrease in the overall firmness of our skin.

When should you start an anti-ageing skincare routine?

According to Dr. Smriti Naswa Singh, Consultant, Dermatology, Fortis Hospital Mulund, Mumbai, "When it comes to anti-ageing, timing is increasingly seen as critical. Rather than waiting until the 50s when deep wrinkles, age spots, and visible skin changes have already set in, experts now recommend starting early and tailoring skincare to age-specific needs. In the younger years, particularly up to the age of 30, skin tends to be more acne-prone due to higher oil and sebum production driven by hormonal activity. During this phase, skincare should focus on managing oil balance with appropriate night creams and serums."

How anti-ageing skincare has evolved over the years?

For many years, the focus of anti-aging skincare was on obtaining immediate and visible results. Many products utilized powerful ingredients that enabled an increase in cellular turnover and allowed the skin to appear smooth quickly. Though these methods were effective in improving the condition of the skin in a short time frame, there were many negatives associated with using these methods, including redness, irritation, and a decreased barrier function of the skin.

These complaints were very common among people with sensitive skin. For this reason, a more cautious, physician-recommended approach that focuses on the long-term strength of the skin rather than the short-term but possibly damaging effects of these products have developed.

Why peptides are becoming a key anti-ageing ingredient?

New age skin science and treatment methods have caused the ingredient list of skin care products to be the main focus. Rather than trying to create a result from force, formulations are now built to support the skin's biological processes, with a key ingredient group growing in popularity known as peptides.

Peptides consist of short chains of amino acids, which are the fundamental components for creating necessary proteins such as collagen and elastin in the body. These proteins are crucial to keeping our skin healthy and tight over time. The unique characteristic of peptides is that they function as messengers to our skin cells to help them repair, rebuild, and strengthen over the course of time. Rather than acting aggressively as many other ingredients do, peptide technology acts gently on the skin.

Other ingredients that support healthy, youthful skin

There have been many technological advancements pertaining to skincare that allow formulations to create extremely uniform and accurate compounds to provide positive benefits with great accuracy. Vitamin B3, for example, supports the skin barrier, leading to a vast increase in both skin radiance and elasticity. Pro-Vitamin B5 hydrates the skin, which provides a soothing effect, particularly useful for individuals with sensitive skin. Peptide-based skincare has one major advantage over alternatives, that is, its anti-inflammatory properties, which are further supported by Edelweiss Extract, a plant-derived antioxidant.

Why protecting the skin barrier is important?

The health of the skin barrier plays an important role in maintaining moisture and preventing water loss from the skin's surface, as well as protecting against the effects of the environment. Additionally, using ingredients that support the skin barrier will support a more robust and less sensitive skin surface, making it easier for the skin to cope with external stresses.

Benefits of peptides for ageing skin

Peptides improve the skin's radiance, firmness, and elasticity. As consumers become more aware about skincare ingredients and their efficacies, they are gravitating toward products that provide a flexible balance compared to other products that focus more on providing drastic benefit or effect.

While previously the purpose of anti-aging products focused mainly on removing the visible effects of old age, today's goal includes building healthy skin, so it has greater strength, flexibility, and ability to maintain itself as it ages (long-term). With skincare products now incorporating safe, science-based, natural formulations designed for resilient skin, we are witnessing a broader paradigm shift in how healthy skin is defined and maintained. For people who want to improve the signs of aging; particularly people with sensitive skin, it is recommended to use products that promote healing without creating additional stress will provide a much more sustainable long-term option.
