Lamination chemical compounds are the active products that execute the structural change in the lash — a three-step protocol in which each step has a different chemical function, a different working time and a different price point.
Lamination Compounds — Why Step 3 Costs More Than Steps 1 and 2
In most lamination systems, the Step 3 compounds (nourishing filler) are significantly more expensive than Steps 1 and 2. It's important to note that this is not pricing policy — it reflects a fundamentally different type of content. Steps 1 and 2 contain chemical agents (perming and neutralising solutions) produced at relatively low cost. Step 3 contains hydrolysed proteins, keratin structures and hyaluronic acid — ingredients with a higher production cost, designed to regenerate the cuticle after the two chemical treatments that precede it.
Format by Step — Which Format for Which Step
Steps 1 and 2 are available in both sachet and bottle format. It's important to note that the bottle format for Steps 1 and 2 is more economical for regular use — a 4 ml bottle covers approximately 15–20 procedures. The sachet format suits infrequent use, system testing, or where maximum sterility per procedure is preferred.
Step 3 (Filler) is currently available only in sachet format — the bottle format is out of stock. This means that for an active practice with regular clients, Step 3 will require more frequent reorders than Steps 1 and 2.
Lashbotox — Substitute or Complement to Step 3
Lashbotox is a nourishing formula containing proteins and keratin components, used more broadly than a standard filler: it can occupy the Step 3 position in the standard protocol (applied after Steps 1 and 2 in place of the filler), or be used independently for clients with damaged lashes without lamination. It's important to note that lashbotox and a standard filler are not identical — lashbotox typically delivers deeper nourishment, but may produce a softer form retention compared to a targeted fixing filler.
Shelf Life by Format
The INLei bottle format for Steps 1 and 2 carries a 36-month shelf life. It's important to note that at moderate treatment frequency, the risk of expiry before use is minimal for bottle format. Sachet formats carry a 12-month shelf life — shorter, but each sachet remains isolated from moisture and contamination until the moment of opening.
Frequently Asked Questions
Can Steps 1 and 2 from different systems be mixed?
Not recommended. It's important to note that different systems are optimised to work with each other — combining Step 1 from one brand with Step 2 from another has not been tested and may produce an unpredictable result.
Can lashbotox be used without prior lamination?
Yes. Lashbotox is a standalone nourishing treatment — lamination is not a prerequisite. For clients with brittle or damaged lashes, a standalone lashbotox procedure is a recommended alternative to lamination.
How long does the lamination effect last?
The chemical reshaping of the lash form is permanent within the natural lash lifecycle — 6 to 8 weeks, after which new lashes grow in untreated. It's important to note that the visible duration of the result depends on the individual client's lash growth rate.
