Senecio LA 25 Vitamin C Serum 25% (15 ml)
Overview
Senecio LA 25 is a high-strength Japanese serum with 25% vitamin C, aimed at a brighter, more even-looking complexion. It uses PLT (Penetrative Liquid Technology) to help the formula reach the stratum corneum. Because it is highly concentrated, start slowly and build up as your skin adjusts.

FAQ
Why does 25% vitamin C tingle at first?
At this strength a mild tingling or warmth is common as skin adjusts. Start with a single drop and build up; if the sensation is strong or persistent, reduce frequency.
Do I need sunscreen with this serum?
Yes. High-strength vitamin C can increase sun sensitivity, so a daytime sunscreen is important both to protect your skin and to help keep the brightening benefit.
Is this an authentic Japanese product?
Yes. We buy through Japanese distribution channels and ship from our base in Kobe, Japan. We do not sell grey-market or parallel-import stock, and the packaging you receive is the Japanese domestic packaging, with Japanese-language labelling.
How many drops should I use?
Begin with one drop per application while your skin adjusts, then increase to two or three drops. A 15 ml bottle lasts a long time at that rate.
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.
