Sei. Botanical Blends - Consciously made

In a world of overstimulation, Sei returns to essentials: cold-pressed oils, minimal essential oils, and certified botanicals - chosen for quiet, effective support.

Sei comes from the Japanese word 静 (sei), meaning calm or stillness. It reflects our philosophy: thoughtful, intentional, and respectful of your skin's natural balance.

Stillness isn't inactivity - it's focus. Our formulas respect your skin's rhythm, using only what's needed, nothing more.

Crafted by Hand
🌿 Each serum is made in small batches
🌿 Cold-pressed, certified botanicals only
🌿 Ingredients chosen for function, not trend
🌿 Essential oils used sparingly - only when they bring real benefit

Freshness Matters
Oils are kept refrigerated from arrival to blending, preserving their potency until they reach your skin.

The result is skincare that's quietly powerful - supporting, never disrupting - so your skin can thrive in stillness.

.rooted in stillness

I founded Sei from a desire to do less, but do it better. In a space where overstimulation is the norm - for both skin and mind - I wanted to return to what's essential. Each blend is an act of restraint and precision: a careful interplay of cold-pressed oils, minimal essential oils, and certified raw botanicals chosen for their quiet efficacy.

Stillness, to me, isn't inactivity - it's focus. A way of working that respects the skin's own rhythm, honors ingredient integrity, and lets thoughtful formulation speak for itself.

The name Sei comes from the Japanese kanji 静 (sei), meaning stillness or calm. It's a reflection of both my philosophy and the formulation style I've developed: thoughtful, deliberate, and deeply respectful of the skin's natural balance.

Every serum is crafted by hand in small batches, using only cold-pressed, certified botanicals sourced from trusted European suppliers. I select each ingredient not for trend, but for function - with minimal essential oils added only where they bring clear benefit. Stored refrigerated from arrival to blending, these oils retain their potency and integrity until the moment they touch your skin.

The result is skincare that's quietly powerful - supporting, never disrupting - so your skin can thrive in stillness.

Every formula begins with one principle: purity first. At Sei, that means cold-pressed oils, sourced exclusively from European suppliers who meet the highest international standards. Every botanical is traceable, certified at source, and stored refrigerated from day one to preserve its integrity.

All base oils carry COSMOS Organic certification and come from producers audited under ECOCERT and ISO 22716 protocols. While my final formulas are not yet certified organic, every step in their making meets those same benchmarks. I work only with partners who share my commitment to quality, transparency, and responsible sourcing.
Each serum is blended in small batches, using less than 2% essential oils to ensure both efficacy and skin compatibility. No fillers, no shortcuts - just focused, functional ingredients chosen for what they can do, not how they sound.

This is skincare built on intention. From the first drop to the last, my commitment is the same: potent, respectful formulations designed for skin that values stillness over stimulation.
