Esther Serum
A Graceful Aging Facial Oil
Our Esther Serum is a nutrient-rich facial oil designed to support graceful aging and restore your skin’s natural radiance. Every ingredient was deliberately chosen for its proven potency. Nothing included by chance. Nothing without purpose.
This luxurious blend is powered by clinically studied plant actives, regenerative botanicals, and bioavailable lipids that soften fine lines, smooth texture, and promote a luminous, even complexion. With powerhouse ingredients like bakuchiol, cacay oil, CoQ10, and seabuckthorn CO₂ , paired with emu oil for enhanced absorption, Esther Serum nourishes deeply while visibly rejuvenating tired, dull, or inflamed skin. It’s gentle enough for daily use and sensitive skin, yet delivers high-performance results you can see and feel.
How to Use:
After cleansing, apply 1–2 pumps to damp skin on the face and neck. Gently press or massage into the skin. Use morning and night. Allow a few minutes for the serum to fully absorb before following up with a small amount of Tallow Balm to seal in moisture.
Main Ingredient Quality Breakdown:
Emu Oil
AEA Certified, pasture raised, no antibiotics, no hormones, raised and rendered in the USA
Rich in essential fatty acids and known for its transdermal absorption abilities, emu oil helps deliver other actives deeper into the skin while reducing inflammation and redness.
Bakuchiol
Wild crafted, 99% purity, cold pressed, Non-GMO
A plant-derived alternative to retinol, clinically shown to match retinol’s wrinkle-reducing and pigmentation-fading effects, but without the dryness or sensitivity.
📚 Backed by a 2018 study in the British Journal of Dermatology.
Rosehip Oil
USDA Organic, virgin, cold pressed, unrefined, Non-GMO
A natural source of trans-retinoic acid (a vitamin A derivative), rosehip oil supports collagen production, fades scars, and improves skin texture and tone.
Jojoba Oil
USDA Organic, cold pressed, unrefined, hexane-free, chemical-free, Non-GMO
Technically a wax ester, jojoba closely resembles human sebum. It balances oil production, softens skin, and enhances the penetration of active ingredients.
Pomegranate Seed Oil
USDA Organic, virgin, unrefined, kosher, Non-GMO
High in punicic acid (omega-5), this oil is a powerhouse for cell regeneration. It firms, improves elasticity, and reduces signs of sun damage.
Cacay Seed Oil
Unrefined, cold pressed, virgin, Non-GMO
A potent, skin-renewing oil naturally rich in pro-vitamin A. Cacay smooths fine lines, improves firmness, and boosts cell turnover without irritation.
Coenzyme Q10 (Ubiquinone)
Pure, bioavailable antioxidant, Non-GMO
A powerful antioxidant that energizes skin cells and helps maintain collagen and elastin. It visibly reduces fine lines and protects against oxidative stress.
Squalane
Sustainably derived from olives, Non-GMO
A stable, lightweight emollient that mimics the skin’s natural sebum. It deeply hydrates and enhances elasticity without clogging pores - perfect for sensitive and aging skin.
Sea Buckthorn
USDA Organic, virgin, kosher, Non-GMO
Extremely rich in omega-7 and carotenoids, sea buckthorn brightens the complexion, repairs barrier damage, and promotes even tone and skin regeneration.
Frankincense Oil
Resin extracted, pure, Non-GMO
Known for its anti-inflammatory and skin-toning properties, frankincense oil minimizes the appearance of pores and fine lines while promoting overall skin clarity.
Helichrysum Italicum
USDA Organic, pure, Non-GMO
Also called “Immortelle,” this oil is revered for its ability to heal and regenerate skin. It’s especially effective for reducing redness, scars, and signs of aging.
Blue Tansy
Pure, Non-GMO
Rich in azulene, which gives it its deep blue color, blue tansy calms irritation and inflammation. Ideal for soothing reactive or acne-prone mature skin.
Vitamin E (Tocopherol)
Plant-derived, antioxidant-rich, Non-GMO
A lipid-soluble antioxidant that stabilizes oils and protects the skin from free radical damage. It also enhances the shelf life and potency of other antioxidants like CoQ10.

Truly a standout product from a brand that clearly cares about quality. Kai tallow encompasses so many of the values I love: transparency, clean, family. Gabi really cares about people over profit. AND The Esther Serum in particular is so unique. Feels great on my skin and a little goes along way. And such a fun gift to give other likeminded friends, especially in the fall season coming up where hydration is a must.
I can’t say enough good things about this serum! Makes my skin so smooth and hydrated, and I have noticed a huge change just over the last 6 weeks in the appearance of my fine lines and overall tone. It’s simply the best!
I love using the Esther Serum as part of my bedtime routine. It goes on easy but doesn't leave your face feeling greasy/oily. I appreciate the quality of your products. Highly recommend.
What a beautiful serum made by such an lovely company.
Gabi really is so talented and works hard to provide real value to her customers. No fillers or harmful ingredients.
The serum is really potent and concentrated and you only need 2-3 pumps for the whole face + neck. I will be buying more for friends and family.
I used the Esther Serum almost every night for 5 weeks, and my skin has never felt so hydrated and silky smooth without feeling oily. It helped my facial redness, reduced sunspots, and kept my occasional acne at bay, and made my fine lines less fine. I would recommend this to everyone.
