Living a fast-paced lifestyle with long days and sleepless nights? YSL Urban Science discovered that the skin of urban all-nighters experiences a week's worth of aggression in just one day, accelerating volume loss, skin sagging, and the appearance of early signs of ageing.

Introducing Youth Reload Serum, a formula with 92% natural-origin ingredients, infused with Iris Flower from the Ourika Community Gardens and our breakthrough Youth Reload Complex [Rhamnose + Proxylane + Collagen Peptide Fractions]. Engineered for transformative skin reshaping, it helps skin look more youthful—visibly lifted, smoother, and plumper. In just 4 weeks, the appearance of fine lines and facial sagging is reduced, while cheekbones appear more lifted.

For the first time, the combined power of our proprietary Iris Flower and Youth Reload Complex has been proven to act 2x faster than peptides*. This powerful synergy delivers unparalleled action across all collagen groups.

Elevate your routine by pairing it with Youth Reload Essence-in-Lotion and Youth Reload Cream for the complete anti-ageing ritual.
