Expert Eyes

Strengthens, densifies, and protects lashes and brows.

As we age or expose our lashes and brows to daily stressors like makeup, pollution, and over-plucking, they can become weaker, sparser, and more prone to fallout. Expert Eyes Fortifying and Densifying Double Serum is a two-step treatment designed to restore density, enhance strength, and promote visibly fuller lashes and brows.

This advanced dual-action formula works in two phases:

Serum No. 1 stimulates growth and fortifies hair follicles, enhancing thickness and resilience.
Serum No. 2 nourishes and protects each strand, reducing breakage and reinforcing density.

With a high-performance blend of peptides, plant-based extracts, and targeted actives, this treatment works at the root level and along the hair shaft to create stronger, healthier, and more defined brows and lashes.

Skin instant:

Ideal for those experiencing thinning, weakened, or sparse lashes and brows due to aging, stress, or external damage. Perfect for individuals seeking to naturally enhance definition and maintain fuller, more resilient lashes and brows.

Benefits:

• Stimulates hair growth – Pea Shoot Extract and Apple Stem Cells reactivate follicles for fuller lashes and brows.
• Strengthens and fortifies – Reinforces the hair structure to reduce breakage and thinning.
• Protects against hair loss – Shields delicate hairs from environmental and cosmetic stressors.
• Enhances lash and brow volume – Densifying peptides and conditioning agents improve fullness.
• Delivers immediate and long-term results – Provides instant hydration while working to strengthen and thicken over time.

How to use:

Step 1 – Serum No. 1 (Fortifying & Growth-Stimulating):

• Using the fine liner applicator, apply a thin line along the lash line and over sparse areas of the brows.
• Let the serum absorb fully before proceeding to the next step.

Step 2 – Serum No. 2 (Protective & Densifying):

• Use the brush applicator to coat lashes and brows, ensuring each hair is covered.
• Allow to dry before applying makeup or additional products.

Use morning and evening for optimal results.

Loshen & Crem’s recommendation:

Expert Eyes Fortifying and Densifying Double Serum is more than just a lash and brow treatment—it’s a solution for long-term resilience and density.

✔ For when lashes and brows look sparse or weak
If you’ve noticed more fallout or gaps, this serum strengthens and replenishes, helping hairs stay anchored and grow thicker.

✔ A must-have for maintaining definition
Even if you haven’t experienced major hair loss, using this serum consistently keeps lashes and brows full and resistant to daily stressors.

✔ Perfect for those avoiding lash extensions or brow treatments
If you want to enhance your natural beauty without relying on artificial enhancements, this formula provides visible results without irritation or long-term damage.

✔ How to integrate it into a strengthening routine:
If lashes feel dry → Use with Solution Demaquillante Pour Les Yeux to prevent unnecessary breakage.
If lash loss is significant → Combine with Creme Contour des Yeux Biosensible to maintain overall lash health.
