💡 Luz visible: lo que tenés que saber

Siempre hablamos de los rayos UV… pero la luz visible (400–700 nm) también puede afectar tu piel—y más de lo que pensás. ⬇️

No viene solo del sol. La luz artificial de pantallas, lámparas y dispositivos también puede penetrar en la piel, contribuyendo a la pigmentación, el envejecimiento prematuro e incluso daño en el ADN.

A diferencia de los UVB (que afectan la epidermis), la luz visible llega a capas más profundas como la dermis e hipodermis, activando distintas respuestas en la piel.

✨ ¿Qué puede provocar?
▪️ Aumento de melanina → manchas, melasma y tono desigual
▪️ Estrés oxidativo (ROS) → degradación del colágeno, arrugas y flacidez
▪️ Oxidación del ADN → daño a largo plazo y posibles mutaciones

💡 ¿Cómo proteger tu piel?
Muchos protectores solares solo bloquean los rayos UV. Para protegerte de la luz visible, elegí:
✔️ Protectores solares con color (con óxidos de hierro)
✔️ Antioxidantes como vitamina C
✔️ Protección diaria de amplio espectro

Tu piel está expuesta a más que solo el sol ☀️ protegela como corresponde.

Visible Light: what you need to know 💡

We all talk about UV rays… but visible light (400–700 nm) can also impact your skin—and more than you think. ⬇️

It’s not just sunlight. Artificial light from screens, lamps, and devices can pe*****te deeper into the skin, contributing to pigmentation, premature aging, and even DNA damage.

Unlike UVB (which affects the epidermis), visible light reaches deeper layers like the dermis and hypodermis—triggering different skin responses.

✨ What can it cause?
▪️ Increased melanin production → dark spots, melasma & uneven tone
▪️ Oxidative stress (ROS) → collagen breakdown, wrinkles & sagging
▪️ DNA oxidation → long-term damage and potential mutations

💡 How to protect your skin
Most sunscreens only block UV rays. For visible light protection, choose:
✔️ Tinted sunscreens (with iron oxides)
✔️ Antioxidants like Vitamin C
✔️ Daily broad-spectrum protection

Your skin is exposed to more than just the sun—protect it accordingly.

Melasma is a complex pigmentary and vascular skin disorder.

It involves abnormal pigmentation and increased vascular activity, which makes it persistent and difficult to treat.

It’s a multifactorial discoloration triggered by UV exposure, hormonal changes, inflammation, oxidative stress, and dermal alterations.

Tranexamic acid helps by reducing excess melanin production and targeting the vascular and inflammatory pathways involved, improving dark spots and promoting a more even skin tone.

✨ Discover the right treatment approach for your skin. Consult a specialist and take the first step toward clearer, brighter skin.
