COSNORI Eyelash Tinting Serum — Deep Black tinted, peptide-rich lash booster 0.3 fl oz (vegan, smudge‑resistant)

COSNORI Eyelash Tinting Serum 01 Deep Black is a tinted, peptide-rich eyelash serum that darkens lashes while nourishing them for stronger, longer-looking results without daily mascara.

Designed in the K‑Beauty tradition, this deep‑black tinted serum combines film-forming pigments and peptides to give immediate definition and ongoing lash care. It works as a light tint and a conditioning treatment, suitable after lash perming and as part of an 8‑week strengthening routine. The formula is vegan and formulated to reduce clumping and smudging while being simple to remove with lukewarm water.

How does this serum give the look of mascara while still caring for lashes?

The COSNORI tinted serum deposits rich black pigment to darken each lash and uses quick-setting film-formers for defined separation, so lashes appear made-up without heavy product buildup. At the same time, a blend of peptides and nourishing agents supports lash elasticity and resilience.

• High‑concentration peptide complex to help fortify lash fibers
• Tinted black pigments for immediate color and definition
• Natural film-forming ingredients to minimize clumps and smears
• Removes easily with lukewarm water — no cleansing oil required

Is this serum safe to use after a lash perm and how should I apply it?

This serum is formulated as a lash‑perm companion to preserve curl and provide nourishment that helps extend perm longevity. Apply a thin, even coat along the lash line after your perm treatment has settled, and use an eyelash curler for best long‑lasting lift.

• Use after perm once lashes feel dry and set
• Apply thin strokes from base to tip for even tinting
• Gently curl lashes post-application to lock the effect
• Daily use enhances visual results over several weeks

How soon will I see thicker or longer-looking lashes?

Immediate visual impact comes from the tint and film‑forming effect, while structural improvements happen over repeated use. Users often notice enhanced definition right away and improved lash strength with a consistent 6–8 week routine thanks to peptide support and conditioning ingredients.

• Instant darkening and separation on first use
• Noticeable conditioning and resilience within weeks
• Recommended 8‑week program for visible strengthening
• Safe for daily application on most skin types

Will this product smudge, flake, or irritate sensitive eyes?

The formulation prioritizes quick fixing and reduced clumping to limit smudging and flaking during wear. It’s made to be irritation‑friendly, but as with any eye product, test on a small area first and discontinue if you experience discomfort.

• Quick-setting texture helps resist smears and flakes
• Vegan formula with skin-friendly peptides and gentle film-formers
• Removes with lukewarm water without oily cleansers
• Patch test recommended for very sensitive skin

Who is this for: COSNORI Eyelash Tinting Serum 01 Deep Black is ideal for anyone who wants a low‑maintenance, mascara-like finish while nourishing lashes—especially people with lash perms, those who prefer a subtler daily look, or anyone following a targeted 6–8 week lash‑strengthening plan. It’s suited to users seeking vegan, easy‑to-remove eye cosmetics that combine instant cosmetic effects with ongoing conditioning.
