Serums That Help Bring Back Glow to Ageing Skin

A glowing complexion is often the first thing to fade as skin ages. Dullness creeps in gradually — the result of slower cell turnover, declining hydration, and a weakened skin barrier. But the right serum can make a visible difference. L'Oréal Paris’ Revitalift Filler Hyaluronic PDRN+ Anti-Wrinkle Plumping Face Serum combines Hyaluronic Acid with bio-tech vegan* PDRN+ in a formula to help target lost radiance and deliver a skin transformation you can see and feel.

Why Does Ageing Skin Lose Its Glow?

Radiance depends on how light reflects off the skin's surface — and that requires smooth texture, even tone, and adequate hydration. As we age, several factors work against this. Hyaluronic acid levels in the epidermis decline sharply, reducing the skin's water-binding capacity and leaving it dull and dehydrated. Meanwhile, the slowdown of cell renewal means dead skin cells accumulate on the surface, scattering light instead of reflecting it evenly.

Deeper in the dermis, oxidative stress caused by UV exposure and pollution triggers inflammatory pathways that degrade collagen and elastin. Glycation — the bonding of sugar molecules to skin proteins — further accelerates this decline, contributing to skin yellowing and loss of luminosity. Research on ageing diversity confirms these processes affect all skin tones, though the visible signs may differ across ethnicities.

What to Look for in a Glow-Boosting Serum

Not all serums are created equal when it comes to restoring radiance. The most effective glow-boosting formulas should address both surface-level dullness and the causes of lost luminosity. Here are the key ingredients to prioritize:

• Hyaluronic Acid: Known to help replenish moisture at multiple skin surface levels, instantly improving light reflection and the look of skin’s smoothness.
• PDRN: Known to help improve overall skin quality, radiance and glow.
• Glycerin: A powerful humectant known to help support the skin's moisture barrier.
• Vitamin Cg: Known to help even out skin tone and boost surface radiance.

How Our Hyaluronic PDRN+ Serum Helps Restore Radiance

L'Oréal Paris Revitalift Filler Hyaluronic PDRN+ Anti-Wrinkle Plumping Face Serum combines two complementary ingredients, Hyaluronic Acid and PDRN+, in a formula that leaves skin glowing, plump and smooth.

The formula works across the skin’s surface, delivering immediate hydration and a visible plumping effect. The serum features a multi-weight HA complex: Macro HA, Micro HA, and Micro-Epidermic HA. It leaves skin looking smoother and reduces the look of fine lines and wrinkles whilst an increase in the skin’s hydration levels helps to create a smooth, light-reflecting surface that gives skin a dewy appearance.

Produced through bio-fermentation, L'Oréal Paris PDRN+ ingredient is pure, vegan*, and 3,000x smaller than a pore for optimal absorption into the skin’s surface. Inspired by K-Beauty skin booster procedures**, it is exclusive to L'Oréal Group. The serum's fluid and lightweight texture delivers an addictive sensory experience — fast-absorbing and non-greasy, leaving skin with a comfortable, glowy finish.

"Over time, our cells produce less HA, less collagen and elastin. PDRN steps in to wake up this metabolism using biocompatible nucleotides the body naturally recognizes. Its action is unique because it creates a true cellular dialogue to boost epidermis vitality and restore skin radiance. In this cross-talk with HA, PDRN goes even further: it resets the capacity of the skin to produce its own HA. A major breakthrough in topical skincare."

#WakeUpYourSkin

"Korea is the epicentre of beauty including aesthetics procedures and there I witnessed the steep rise of skin boosters (yes I did it too). So, when I started working on the Filler-procedure inspired Filler franchise pioneering Hyaluronic Acid, it was only natural that I explored the skin booster key active PDRN. Now our No.1 Anti-ageing serum is powered by Hyaluronic Acid and biotechnological PDRN (not salmon!) to help enhance your skin quality, glow and elasticity!" — Chang Yeunhee, Global Skincare Marketing Director, L'Oréal Paris
