Ectoin
One of the standout ingredients within Soothe Serum.
Ectoin is a multifunctional stress-protection and hydration-supporting molecule used to help protect cellular structures against environmental stress while supporting moisture retention.
For the skin, this translates into support for:
Hydration + resilience + barrier comfort + reduced sensitivity to environmental stress.
It is particularly useful when skin feels dehydrated, fragile or reactive.
Panthenol
Also known as Pro-Vitamin B5.
Panthenol is a humectant and skin-conditioning ingredient that helps:
Attract moisture + soothe discomfort + support barrier recovery + improve softness.
It is particularly useful when the skin feels dry, tight or irritated.
Centella Asiatica Extract
A well-established soothing botanical.
Centella helps support skin comfort and visible recovery when the complexion feels stressed or reactive.
Within this formula, it complements Panthenol, Allantoin and Ectoin particularly well.
Trehalose
A naturally occurring moisture-binding sugar.
Trehalose helps support hydration while improving the skin's ability to maintain moisture during periods of environmental or dehydration-related stress.
Sodium Hyaluronate
The sodium salt of Hyaluronic Acid.
It acts as a humectant, helping attract and retain water within the skin.
This supports:
Hydration + softness + visible plumping + smoother-looking dehydration lines.
Allantoin
A soothing, skin-conditioning ingredient that helps improve comfort while supporting softer, smoother skin.
It is especially useful within formulas intended for dry, sensitive or irritated skin.
Lactobacillus Ferment Lysate
A ferment-derived skin-conditioning ingredient.
Within Soothe Serum, it provides complementary support for skin condition and barrier resilience.
For Chris & Alley, I would keep this wording conservative rather than claiming that the serum fundamentally alters or “repairs” the skin microbiome.
Bacillus Ferment
A second ferment-derived ingredient providing complementary conditioning support.
It adds to the formula's broader barrier-supportive profile.
Acetyl Heptapeptide-4
A cosmetic peptide included within the formula's barrier-focused complex.
It is used within skincare aimed at improving skin resilience and barrier quality.
For customer-facing copy, I would position it as:
Complementary peptide support for a stronger, more resilient-looking skin barrier.
rather than making aggressive microbiome-modulation claims.
Green Tea Extract
Provides antioxidant polyphenols and complementary soothing support.
It helps defend stressed skin against environmental oxidative stress.
Licorice Root Extract
Provides soothing and complexion-supportive benefits.
It can help improve the appearance of visible redness while complementing the formula's broader calming profile.
Scutellaria Baicalensis Root Extract
Provides antioxidant and skin-conditioning support.
Polygonum Cuspidatum Root Extract
A botanical source of antioxidant polyphenols that helps complement the serum's environmental defence system.
Chamomile Extract
Provides additional soothing and skin-conditioning support.
Rosemary Leaf Extract
Contributes antioxidant support within the botanical complex.
Niacinamide
Although positioned lower in the current INCI, Niacinamide contributes complementary:
Barrier + hydration + skin-resilience support.
It should remain a secondary supporting ingredient rather than one of the headline actives.

Apply to thoroughly cleansed skin once or twice daily.
Dispense a small amount and gently pat over the:
Face + Neck + Chest
until completely absorbed.
Follow with an appropriate moisturiser to help seal in hydration.
Morning
Finish with a broad-spectrum SPF 30–50+, with SPF 50+ preferred for comprehensive daily protection.
Evening
Follow with your chosen moisturiser or barrier-support cream.
During periods of increased dryness, sensitivity or irritation, Soothe Serum may be reapplied to affected areas as needed, provided the skin remains comfortable.
