Description
La Sincia SE100 Boost Up Essence No.Zero — Booster Essence, 60 ml
Overview
A booster essence designed to be used before the rest of your routine. Unlike a treatment serum, No.Zero is not meant to deliver a result on its own — its stated purpose is to prime the skin so that the lotion and essence you apply afterwards absorb more readily. The name “No.Zero” refers to that position: the step before step one.
La Sincia is the home-care line of the Japanese salon brand La Sincere, which supplies aesthetic salons across Japan. The SE100 Super Essence range is its concentrated essence tier.
It uses a liposomal carrier built from phytosterols — molecules compatible with both water and oil — together with glyceryl glucoside and hydrolysed hyaluronic acid for hydration. The unscented formula makes it easy to add to an existing routine.

Who Is This For?
- Anyone who feels their current lotions and serums sit on the skin rather than sinking in
- People building a layered Japanese routine who want a dedicated priming step
- Dry or mature skin that wants an extra hydration layer at the start of the routine
- Those who prefer an unscented product they can combine with what they already own
- Less useful for anyone wanting a single active treatment — this is a primer, not a serum
How to Use
- Use on cleansed skin, morning and/or evening.
- Apply about half a dropper to the palms or fingertips.
- Press gently over the whole face, avoiding the eye area.
- Immediately follow with your usual lotion, essence or serum while the skin is still slightly damp.
- Alternatively, mix one to three drops directly into the lotion or serum in your palm before applying.
Frequency: Daily, morning and/or evening, as the first leave-on step after cleansing.
Full Ingredients
Actives named by the manufacturer: a liposomal (phytosterol) carrier structure, glyceryl glucoside (marketed as an “aquaporin” ingredient), hydrolysed hyaluronic acid, ume (Japanese plum) extract, chamomile flower extract and propanediol.
This is an actives list, not a complete INCI. A 60 ml aqueous essence also contains water, solvents and a preservative system that the manufacturer's summary does not spell out; we have not filled in the rest. Read the full list printed on the carton, and if you have a specific allergy, message us before ordering and we will read the Japanese label for you.
Ingredient list as declared by the manufacturer. Formulations are occasionally revised, so always read the list printed on the package you receive.
Cautions
- This is a priming essence, not a sunscreen or a treatment product — it does not replace a moisturiser or SPF.
- If you layer several products, introduce them one at a time so you can tell what your skin is responding to.
- Patch test on the inner forearm before first use, especially if your skin is reactive.
- Discontinue use and consult a doctor if redness, itching, swelling or persistent stinging occurs.
- Avoid contact with the eyes. If the product enters the eyes, rinse immediately with plenty of water.
- Do not apply to broken, sunburned or actively inflamed skin.
- Keep out of reach of children. Store away from direct sunlight and high temperatures.

FAQ
What does a booster essence actually do?
It is applied first, on freshly cleansed skin, to leave the surface hydrated and receptive before your other products go on. The maker builds it around a liposomal carrier and humectants like hyaluronic acid, so the skin feels conditioned rather than tight when you layer the next step. Think of it as preparing the canvas rather than being the paint — it is meant to make the products after it work more comfortably, not to replace them.
Can I use it on its own?
You can, but it is not designed to be a complete routine by itself. It has no sun protection and is not a rich moisturiser, so on most skin you would still want a lotion or cream afterwards. Its value is in the sequence: primer first, then your usual treatment and moisture steps.
The description mentions “aquaporin” and “water channels” — is that proven?
That is how the brand explains glyceryl glucoside, one of the ingredients: aquaporins are real water-transport proteins in skin cells, and the marketing draws on that idea. What is well established is that glyceryl glucoside is an effective humectant that helps hold water in the outer skin. We would treat the “water channel” language as the brand's framing rather than a measured effect on your face.
Is this product halal or suitable for vegans?
The actives named are plant- and sugar-derived, so nothing in the disclosed list is animal-sourced; however the full INCI is not published here, so we cannot state it is fully vegan. The product carries no halal certification — Japanese domestic cosmetics are rarely certified — so if certification itself matters to you, this product does not have it.
Will I pay customs duty or import VAT?
That depends on your country and on the declared value of the parcel, not on us. We ship from Japan with a correct customs declaration and full tracking; any duty or import VAT your country charges is collected by your local carrier or customs office on delivery. Check your national de-minimis threshold before ordering if you want to avoid a surprise.
