InLei Lash Molecular 4 Sachets – 9 × 1.2ml

InLei Lash Molecular 4

InLei Lash Molecular 4 is the final molecular reconstruction stage of the professional InLei Lash Filler 25.9 treatment. This no-rinse gel enhances the benefits of the preceding treatment steps while helping rebalance the structure of natural eyelashes and eyebrows.

The formula combines carefully balanced vegetable proteins with an advanced form of hyaluronic acid. It supports improved hydration, strength, flexibility, shine and colour retention while leaving the treated hairs feeling soft and conditioned.

Molecular Lash Reconstruction

The protein components work at different levels of the hair. Higher-molecular-weight components form a light film over the lash shaft, helping lubricate and strengthen the cuticle while supporting protection from everyday physical and chemical stress.

Lower-molecular-weight components penetrate further into the hair cortex. They help retain moisture, improve elasticity and reinforce the lash structure from within. This dual action makes the reconstruction gel a valuable finishing step after a professional lash lift.

Vegetable Proteins and Hyaluronic Acid

InLei Lash Molecular 4 contains several targeted ingredients chosen to condition and reinforce natural eyelashes and eyebrows after professional treatment.

• Hydroxypropyltrimonium Hyaluronate: An advanced form of hyaluronic acid that adheres to the hair surface, helping attract and retain moisture for smoother, softer and shinier hairs.
• Hydrolysed Quinoa: A complete protein containing essential amino acids that supports strength, firmness, shine and lasting colour intensity.
• Hydrolysed Wheat Protein: Helps retain moisture within the hair, improve elasticity and form a light protective barrier over the surface.
• Hydrolysed Vegetable Protein: Uses different molecular weights to reinforce the hair internally while creating a protective film over the cuticle.

Protection for Treated Lashes and Brows

Natural lashes and brows can experience mechanical stress from rubbing, sleeping, makeup application and the regular use of styling tools. Chemical treatments such as lifting, tinting and bleaching may also affect the condition of the hair.

This professional lash reconstruction treatment is designed to help counteract these stresses. Its low-molecular-weight proteins support the hair internally, while larger components help protect and lubricate the outer surface.
