A Stronger Green Enzyme Blend
E-terna is built on the same live enzyme foundation as everything we make — but stronger. Green papaya, green mango, gotu kola, aloe vera, and holy basil form a more potent, more active enzyme complex, formulated specifically for the resilience needed on neck and hands.
A Food-Grade Neurotransmitter-Inspired Blend
NMN, GABA, glycine, and MSM — a food-grade blend inspired by the body’s own neurotransmitters, formulated to work at the skin’s surface to help minimise the visible look of fine lines over time.
Niacinamide & Fermented Rice Peptides
Niacinamide helps even tone, while fermented rice peptides support hydration and the skin’s own barrier — the same renewal story found throughout the Sparrow range, concentrated further here.
CoQ10 & Allantoin
CoQ10 brings its own antioxidant support, while allantoin calms and soothes — two quiet workhorses doing their part in a formula built for skin that works hard every day.
Nourished & Protected
Shea butter, avocado oil, and sweet almond oil nourish deeply, while zinc oxide acts as a skin protectant and beeswax helps seal it all in — rich, but never greasy.
Waterless, By Design
A true concentrate — no water in the formula, so nothing is diluted before it reaches you. A small, pea-sized amount is all it takes.
Neck, Hands — Not Face
Formulated specifically for the thicker, more resilient skin of the neck and hands. Not intended for facial use.
Handcrafted, By Hand
Like every Sparrow formula, E-terna is handcrafted personally by our founder in small batches, with ingredients sourced from small organic farms visited in person, trusted suppliers, or grown on our own balcony at home.
