Dr. Sonia Tejada Solís is a neurosurgeon with over twenty years of clinical experience and a growing career in longevity medicine. Her vision of skin care does not stem from beauty marketing, but from a systemic understanding of human aging: the skin as an expression of what happens in the entire organism, not as an independent surface to be managed with creams.
The longevity medicine approach to skin care
From the perspective of longevity medicine, the skin is not the primary objective: it is one of the tissues in which systemic aging is most visibly expressed. The same mechanisms that deteriorate cardiovascular function, cognition, and metabolism—oxidative stress, inflammaging, mitochondrial dysfunction, telomere shortening—also degrade the skin. Therefore, the most effective interventions for the skin are, to a large extent, the same as those for general longevity.
Why prevention is always smarter than correction
Dr. Tejada expresses it precisely: "Care as a system begins long before any intervention." This phrase summarizes one of the most solid principles of preventive medicine applied to the skin. Once collagen has been lost, once elastin has irreversibly deteriorated, once photodamage has accumulated, correction is partial and costly. Sustained prevention over years yields a return in skin quality that no punctual correction can replicate.
What it means to formulate with criteria according to preventive medicine
From a preventive medicine approach, a nutricosmetic formulation with criteria is defined by three characteristics: it uses ingredients with published clinical evidence (not just ingredients with good marketing headlines), it combines them at real functional doses (not symbolic ones), and it considers the synergies between active ingredients (it does not accumulate them randomly). LEVIAL's formula—with its three axes and 14 selected active ingredients—responds exactly to this logic: it is not a list of trendy ingredients, it is an architecture with scientific rationale.
The role of micronutrients in long-term skin care
Longevity medicine pays special attention to micronutrients that tend to fall below optimal levels with age: zinc, selenium, vitamin D, CoQ10. These are not clinical deficiencies with obvious symptoms, but rather suboptimal levels that reduce the efficiency of repair and protection mechanisms. Correcting these levels with precise supplementation is an intervention with a very favorable risk-benefit ratio.
Recommendations for a woman aged 40+ who wants to take care of herself wisely
The approach that emerges from longevity medicine for skin care in women aged 40+ is systemic: daily photoprotection without exception, an anti-inflammatory diet rich in polyphenols and omega-3, active stress management, targeted supplementation with reference ingredients, and well-tolerated active cosmetics. It is not a long and complex list: it is a coherent strategy where each element has a clear purpose. LEVIAL, according to Dr. Tejada, "can be coherently integrated into a preventive approach oriented towards long-term well-being."
