CAPRYLOYL METHIONINE/SILK AMINO ACIDS METHYL ESTERS.

Valuable / HAIR CONDITIONING, NAIL CONDITIONING

A sophisticated thio-lipester complex that merges sulfur-rich methionine with silk-derived amino acids in a highly bioavailable, lipid-compatible form. This precision ingredient is engineered to reinforce the structural integrity of keratinized tissues, specifically targeting the hair bulb and nail matrix for enhanced resilience.

Hair conditioning Nail strengthening Keratin stimulant Anti-seborrheic

Science

By functioning as a delivery vehicle for essential sulfur amino acids, this lipoamino acid penetrates the epidermis and follicle to stimulate keratin synthesis. It promotes cellular development at the root, strengthening the fiber structure of hair and nails from the inside out while balancing sebum production.

Key findings

  1. 01 Clinical evaluations of the ANP 2+ complex at a 40% concentration demonstrated an 85% reduction in hair loss within 60 days and a 67% visible regrowth rate after 120 days.
  2. 02 Eyelash-specific trials reported measurable increases in volume and length within a 21 to 30-day window of consistent application.
  3. 03 Seborrhea improvement was noted in 91% of participants, indicating significant scalp-balancing properties.
