Preguntas frecuentes

What does it mean that it contains "four stabilized derivatives of Vitamin C"?
It means that Tetra Vitamin C 26 combines different forms of Vitamin C (such as 3-O-Ethyl ascorbic acid, Ascorbyl glucoside, Ascorbyl palmitate, and Ascorbic acid). This synergistic combination not only allows for a gradual and sustained release of vitamin C in the skin but also ensures greater stability of the product, preventing the rapid oxidation that often occurs with pure Vitamin C.
¿Cuáles son los cuatro derivados de Vitamina C que contiene y qué aporta cada uno?
Tetra Vitamin C 26 concentra cuatro derivados estabilizados con funciones complementarias. El Ácido 3-O-Etil Ascórbico (12%) es un derivado muy estable y soluble tanto en agua como en aceite, con excelente capacidad de penetración, que aporta luminosidad, uniformidad y estimula la producción de colágeno. El Ascorbil Glucósido (5%) es un derivado estable que se convierte en ácido ascórbico dentro de la piel, ofreciendo beneficios antioxidantes e iluminadores. El Ascorbil Palmitato (5%) es la forma liposoluble de la Vitamina C, que penetra bien en la piel y aporta protección antioxidante mientras favorece la síntesis de colágeno. Por último, el Ácido Ascórbico (4%) es la forma pura y más potente de la Vitamina C, un antioxidante esencial que mejora la luminosidad, unifica el tono y combate el envejecimiento.
How does this serum help to unify skin tone and reduce blemishes?
Vitamin C is a powerful inhibitor of melanogenesis (the process of melanin production), which helps reduce the appearance of dark spots (sun-related, post-inflammatory) and prevents the formation of new ones. At the same time, its antioxidant action and its ability to promote cell renewal contribute to a more even and radiant skin tone.
Can I use Tetra Vitamin C 26 both in the morning and at night?
Yes, Tetra Vitamin C 26 can be used in both your daytime and nighttime routine. In the morning, it acts as a powerful antioxidant that protects the skin from environmental damage (free radicals, pollution) and provides radiance. At night, it helps with skin repair, collagen stimulation, and tone unification.
Is it necessary to use sunscreen if I use Vitamin C in my routine?
Absolutely yes. Although Vitamin C is an antioxidant that offers some protection against the free radicals generated by the sun, it does not replace sunscreen. For complete defense against sun damage and to enhance the benefits of Vitamin C (preventing spots from returning or darkening), it is essential to apply a broad-spectrum sunscreen (SPF 30 or higher) every morning.
