Peptides

What they are

Peptides are short chains of amino acids that serve as building blocks for proteins such as collagen and elastin. In skincare, peptides are synthetically created to mimic those naturally found in the body, ensuring stability and efficacy.

How they work in skincare

In dermatology, peptides are used in anti-ageing serums and creams to stimulate collagen production and improve skin elasticity. They are often paired with other active ingredients such as hyaluronic acid to enhance their effectiveness.

The benefits of peptides include reduced fine lines, improved skin firmness, and enhanced hydration. They support the skin’s repair process, making them ideal for mature or damaged skin. Peptides are gentle and well-tolerated, making them a popular choice for those seeking a youthful glow.

PDRNs (Polydeoxyribonucleotides)

What they are

PDRNs are fragments of DNA derived from purified biological sources. They have a long history of use in medical settings for wound healing and tissue repair and more recently have become established within dermatology and aesthetic medicine.

How they work in skincare and skin health

PDRNs work by supporting cellular repair and regeneration. They interact with skin cells to encourage healing responses, improve tissue quality and reduce inflammation. This makes PDRNs particularly valuable for compromised, post-procedure and aged skin.

In aesthetic practice, PDRNs are commonly used within injectable skin boosters and recovery-focused treatments. Their use in skincare and aesthetics varies by formulation and regulation, which is why professional guidance matters. Rather than stimulating aggressively, PDRNs support the skin’s natural repair mechanisms making them well-suited to sensitive and depleted skin.

Pollution and Skin

What it is

Pollution and skin is a significant but often overlooked link when it comes to skin ageing and damage. Tiny particles from polluted air can penetrate the skin, causing oxidative stress, inflammation, and even breakouts. Over time, this contributes to premature ageing, uneven skin tone and weakened skin barrier function.

How it works in skincare

To combat pollution, use antioxidant-rich skincare products such as vitamin C or niacinamide, which neutralise free radicals. Double cleansing at night removes pollutant particles, and applying SPF daily protects against environmental aggressors.
