DHC Eyelash Tonic Strengthening Lash Serum 2-Pack, 0.21 fl oz Each — Conditioning, Clear Gel for Brittle or Post-Extension Lashes

DHC Eyelash Tonic is a clear conditioning gel that helps strengthen fragile lashes, reduce breakage, and support healthy new growth.

This two-pack of 0.21 fl. oz. lash tonic combines botanical extracts like ginseng, comfrey, aloe and Swertia japonica in a lightweight, colorless serum you can apply day or night. The formula is designed to reinforce individual hairs and protect delicate lashes during routine makeup wear or after extension removal. Applied precisely along the lash line, it conditions without flaking or visible residue, so it layers easily under mascara or alone for overnight care.

How do I use this tonic with my daily makeup routine?

Apply a thin stroke of tonic to clean, dry lash roots before mascara. The clear gel absorbs quickly and won’t interfere with your mascara’s finish. For best results, use once daily—either in the morning under makeup or as a nightly conditioning step.

• Remove eye makeup fully before application.
• Use the built-in applicator to sweep along the upper lash base.
• Allow a few seconds to set before applying mascara.
• One 0.21 fl. oz. vial provides multiple weeks of daily use; two-pack extends routine.

Will this help lashes that are brittle or damaged after extensions?

The tonic is formulated to support fragile lashes often seen after extension removal by moisturizing and strengthening each strand. Its botanical blend targets flexibility and resilience, helping reduce snapping and gradual thinning. Regular use can improve the feel and manageability of weakened lashes.

• Soothes and conditions hair cuticle with aloe and comfrey.
• Ginseng and Swertia japonica help nourish the lash environment.
• Safe to incorporate into post-extension recovery routines.
• Colorless formula avoids staining or visual buildup under extensions.

How quickly will I see improvements in lash strength?

You may notice lashes feel softer and less prone to breaking within a few weeks of consistent use, though results vary by individual. Because growth cycles differ, visible changes in lash length or fullness can take longer and depend on continued application. The tonic focuses on protecting existing hairs and creating a healthier base for natural regrowth.

• Daily application supports cumulative conditioning benefits.
• Expect incremental improvements; persistent use recommended.
• Combine with gentle makeup removal and avoid rubbing to enhance results.

Can I wear this tonic overnight, and is it safe under mascara?

Yes—this clear serum is formulated for flexible use: wear it alone overnight for intensive conditioning or under mascara during the day. It’s lightweight and non-greasy so it won’t cause mascara to clump, and it won’t leave a noticeable film when left on while you sleep. Always apply to clean lashes for maximum comfort.

• Night application provides uninterrupted conditioning time.
• Daytime use layers neatly beneath mascara without altering finish.
• Avoid direct contact with eyes; rinse if irritation occurs.

Who is this for: DHC Eyelash Tonic in this two-pack is aimed at people with brittle, thinning or fragile lashes, those recovering from eyelash extensions, and anyone looking to add a clear conditioning step to their lash-care routine. It suits users who want a subtle, easy-to-use serum that integrates with both morning makeup and nighttime care without leaving color or residue.
