Everyone is different, so be kind to yourself. Consistency is key: a daily routine and a little patience will allow you to achieve lasting and satisfying results.

Why and how does the serum work?
Theyia Eyelash Serum works by stimulating the natural growth phase of eyelashes. Carefully selected ingredients penetrate deep into the lash follicles, nourishing and strengthening the hair fibers. This unique combination helps prevent breakage, promotes fuller lashes, and extends their lifespan, revealing naturally beautiful eyes.
- The serum contains peptides and botanical extracts that activate the roots of the eyelashes to stimulate growth.
- Moisturizing ingredients, such as glycerin and hyaluronic acid, prevent dryness and improve the flexibility of eyelashes, reducing their fragility.
- Vitamins and proteins strengthen lash fibers, making them appear thicker and fuller.
- Agents such as antioxidants protect eyelashes from external aggressions such as pollution or makeup products.
This allows you to achieve longer, denser and stronger eyelashes in just a few weeks, for a naturally intense look without extensions.
Apply regularly and let Theyia serum transform your lashes.
