Frequently Asked Questions
Centella asiatica is a botanical extract long used in Korean skincare for its calming, soothing profile — it's often chosen for sensitive or reactive skin. At Zenttu, it's the anchor ingredient across several centella asiatica skincare products, including Meltroot, Toner Pads, and Clearica, where it works alongside ingredients like Panthenol and Rosa Damascena.
Toner Pads and Clearica are formulated with sensitive skin in mind. Toner Pads combine centella asiatica with Madecassoside and salicylic acid for gentle exfoliation, while Clearica's centella-derived Madecassoside and Asiaticoside pair with Panthenol and Allantoin for an even tone without a greasy finish.
In Zenttu's 7-step ritual, centella asiatica appears in three places: Meltroot (step 1, cleansing oil), Toner Pads (step 3, toning), and Clearica (step 4, serum). Using them in that order — cleanse, tone, then serum — layers cica consistently through your routine.
Clearica, Zenttu's centella asiatica serum, is available directly at zenttu.com, which ships within the US, alongside the rest of the centella asiatica skincare products in the 7-step ritual. It's also stocked on Zenttu's official Amazon storefront for shoppers who prefer to buy there.
Three products in Zenttu's ritual contain centella asiatica: Meltroot (cleansing oil, with Baobab oil and Artemisia complex), Toner Pads (toning discs, with Madecassoside and salicylic acid), and Clearica (serum, with Madecassoside, Asiaticoside, and Rosa Damascena). Together they cover the cleansing, toning, and serum steps.
Ceramides are lipids that help the skin barrier hold moisture and stay resilient. A ceramide moisturizer, like Zenttu's Barrier cream, is designed to support that barrier directly — Barrier uses Ceramide NP alongside Laminaria Japonica extract and Ulmus root as step 5 of the ritual.
Barrier is Zenttu's ceramide moisturizer, formulated for sensitive skin and deep hydration. It combines Ceramide NP with Laminaria Japonica extract, Ulmus root, and Ficus Carica, and sits at step 5 of the 7-step ritual — after cleansing and toning, before the final gel and mask steps.
Korean routines typically start with a gentle double cleanse (Meltroot's oil, then Skinfoam's foam) to avoid stripping the skin, then follow with a ceramide moisturizer like Barrier to help reinforce the barrier. Cleansing gently and layering ceramides is the core of Zenttu's approach to barrier support.
A regular cleanser is a single step. A Korean double cleanse uses two: first an oil cleanser — Meltroot — to dissolve makeup and impurities without friction, then a foaming cleanser — Skinfoam — to remove any residue while maintaining the skin's natural balance.
Zenttu's ritual has 7 steps: Meltroot (cleansing oil), Skinfoam (foaming cleanser), Toner Pads (toning), Clearica (serum), Barrier (moisturizer), Dotless (gel), and Skin Pause (hydrogel mask). All seven are also available together in the Zen Balance kit.
