A dermatologist-developed lash serum formulated to visibly strengthen, nourish, and enhance the appearance of eyelashes for a fuller, longer, and more defined lash look. Dr. Althea's Lash Boost Serum delivers a concentrated blend of lash-conditioning actives directly to the lash line via a precision applicator, targeting weak, thin, or sparse lashes and the delicate follicle area to support healthier, more resilient lash growth over time.

Key Benefits

• Visibly Fuller & Longer Lashes — Lash-nourishing actives work at the lash line to support the growth cycle and improve the visible density, length, and definition of lashes with consistent use, reducing the appearance of thin or sparse lashes.
• Strengthens & Conditions Lashes — Conditioning formula coats and penetrates the lash shaft to reinforce its structure, reducing brittleness, breakage, and lash fall caused by makeup use, lash curlers, or environmental stress.
• Nourishes the Lash Follicle — Active ingredients target the lash follicle at the root to create a healthier foundation for lash growth, supporting the natural growth cycle for stronger, more resilient lashes over time.
• Dermatologist Developed & Eye-Safe — Formulated with Dr. Althea's clinical expertise for use in the sensitive eye area, with eye-compatible actives designed to minimize irritation risk while delivering effective lash-enhancing results.
• Precision Applicator — Fine-tip applicator allows accurate, controlled application directly along the upper lash line for targeted delivery of active ingredients exactly where they are needed.

How to Use

Apply to clean, dry upper lash line each evening before bed, similar to eyeliner application. Start from the inner corner and draw along the upper lash root to the outer corner. Allow to dry fully before applying other eye products or going to sleep. For best results, use consistently for a minimum of 4–6 weeks. Remove contact lenses before application if applicable.
