“The skin does not age all at once: it does so when it loses its rhythm, when its renewal processes cease to be efficient and begin to manifest fine lines or irregular texture,” says Raquel González, cosmetologist and founder of Byoode. The expert brings us a concept often forgotten and that is key for skincare in which facial rejuvenation is the main goal.
Not only is hydrating, exfoliating and applying actives that work like vitamin C enough. The skin needs to renew itself, and the passage of time reduces the effectiveness of this process. As a consequence, signs of aging become increasingly visible and irreversible. This is why experts recommend having a cosmetic product on hand that can reactivate those key processes from within. And we know which ones they are.
“Cellular renewal is the true thermometer of young skin. When this process functions correctly, the skin appears brighter, more even and firmer, and responds better to any subsequent treatment,” says Estefanía Nieto, Director of Dermocosmetics at Medik8.
However, with the passing years and having spent so long exposed to environmental factors, this natural mechanism slows down. “A skin that does not renew well accumulates aged cells on the surface and loses quality in depth,” notes Irene Serrano, Director of Dermocosmetics at Dermalogica.
So, how do we achieve that change in the skin from within? People often think exfoliation is what you need, but science has evolved and now there are products that go one step further. “Exfoliating is important, but it is not enough if we do not help the skin regenerate better,” points out the Dermocosmetics Director at Dermalogica. And these serums are the best examples.
Exosomes
Among the latest market novelties is Dermalogica Phyto Nature E2, a daily-use, light and silky product that combines enzymes and exosomes in a revolutionary formula that promotes the skin’s natural regeneration from the inside every day. Exosomes are natural messengers that transport valuable active ingredients directly to skin cells to activate regeneration and renew the skin from within. Clinical studies show that cellular renewal accelerates and fine lines and wrinkles are reduced in only two weeks. Price: 176 euros.
Retinol
Besides exosomes, one of the actives that aid cellular renewal is retinol. This is the case of Premium Retinol One Million by SkinClinic, an intensive booster formulated with high-concentration palmitate retinol, designed to boost the action of your regular cream. It promotes cellular renewal, improves firmness, and helps smooth wrinkles and marks, providing a smoother, more even, and luminous appearance. Suitable for skin accustomed to using retinoids or as an intensification phase of treatment. Price: 72 euros.
Growth Factor
Finally, a formula that enhances the effects of retinol: Growth Factor Firming & Lifting Serum by Perricone MD. This serum uses retinol and a polyamine growth factor derived from synthesized spermidine and eggshell membrane to improve skin hydration and protect it. It includes retinol encapsulated at a low concentration to accelerate cellular renewal without causing irritation. “Spermidine is a direct activator of cellular recycling pathways. Unlike retinoids, which stimulate renewal from the outside, spermidine acts from the nucleus, helping the cell repair itself,” notes Fernández from Perricone MD’s Dermocosmetics department. Price: 147 euros.
Péptidos
If you are looking for a comprehensive option that acts on different signs of aging, try CellularYouth Longevity Serum from Paula’s Choice. Its formula targets 12 signs of aging, reducing them and slowing their progression at all stages. Thanks to a disruptive technology that favors NAD⁺ and to cutting-edge ingredients such as taurine, exosomes, and peptides, it helps recharge cellular energy and strengthen the body’s natural repair mechanisms, restoring firmness, smoothness, and radiance. The result is a skin that is more resilient, revitalized, and visibly younger in the long term. Price: 75 euros.
