How do I use DELA Lash Serum?

Start with clean, dry skin. Apply one thin, precise stroke along the upper lash line once daily. Avoid direct contact with your eyes. Stop using the product if irritation occurs.

When should I expect a difference?

Consistency matters. Changes in lash appearance can take time and vary from person to person. Make it part of your daily routine rather than expecting an overnight transformation.

What is inside the formula?

DELA uses a multi peptide approach with conditioning ingredients including panthenol and supporting ingredients including biotin. Explore the formula section for the ingredient information and the thinking behind each component.

Which bundle should I choose?

Choose one tube to begin your routine, or two or three tubes if you prefer to keep a supply on hand. Each tube contains 3 mL. Select a bundle above to see its total before adding it to your bag.

RESEARCH / THE SOURCES

Evidence, in context.

A closer look at published ingredient research, including what it does and does not establish for DELA Lash Serum.

PEPTIDES / HAIR RESEARCH

How peptide structure matters.

Published work has examined how peptide structure influences penetration into human hair. This provides context for peptide formulation, not proof of lash growth from DELA’s selected peptide blend.

Peptide structure: Its effect on penetration into human hair
PANTHENOL / CONDITIONING

Care for the hair fibre.

Cosmetic ingredient assessments identify panthenol as a hair conditioning ingredient. Laboratory research also examines its interaction with hair proteins. These findings concern ingredient behaviour in hair, not measured results from the finished DELA serum.

Cosmetic ingredient safety assessmentPanthenol and hair protein research
BIOTIN / SUPPORTING ROLE

The whole formula matters.

Biotin is included as a supporting ingredient. NIH guidance notes limited evidence for hair benefits from biotin supplementation. Nutritional research does not establish that topical biotin increases lash growth.
