Low-molecular-weight hyaluronic acid supports skin hydration by helping bind water within the skin matrix, improving smoothness, suppleness, and visible radiance.

What is hyaluronic acid?
Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan found throughout the skin, joints, and connective tissue. In skin, it acts as a powerful water-binding molecule within the extracellular matrix, helping maintain hydration, suppleness, and comfort.
In supplements, hyaluronic acid is typically provided as sodium hyaluronate, a stable and well-studied form that allows for consistent dosing and absorption.
How it works
After oral intake, hyaluronic acid is broken down into smaller fragments that can influence hydration signaling and water balance in the living layers of skin. Improved internal hydration helps support the skin barrier and reduce transepidermal water loss (TEWL), meaning less moisture escapes through the surface.
In practical terms, better hydration from within supports smoother-looking skin and a more resilient barrier, especially when hyaluronic acid is paired with ceramides (to reinforce barrier lipids) and vitamin C (to support normal collagen formation).

Why itâs in BOOST
BOOST is designed to cover daily skin fundamentals from the inside out. Hyaluronic acid supports the skinâs internal water reservoir, ceramides help maintain barrier lipids, vitamin C supports normal collagen formation, and astaxanthin and SkinAx²Ž contribute to everyday antioxidant defense.
Together, these components are designed to support hydration and barrier function more durably than surface-only approaches.

Supplement vs. topical
Topical hyaluronic acid and moisturisers act at the surface and are effective for immediate comfort. Oral hyaluronic acid works from within the living skin layers, supporting hydration dynamics and barrier behavior over time.
Using both is complementary. Take BOOST in the morning, then apply your topical hyaluronic acid or ceramide moisturiser and SPF for surface-level support.
Dosage context
What BOOST provides
120 mg hyaluronic acid per day (as sodium hyaluronate, ~80 kDa; per 2-capsule serving).What research uses
Human studies investigating skin hydration and elasticity commonly use approximately 120â240 mg per day, with some effects reported at lower intakes. Changes typically emerge over 4â8 weeks and consolidate by around 8â12 weeks.How this fits
120 mg per day sits within the skin-focused clinical range and is paired in BOOST with ceramides and vitamin C to support both water binding and barrier integrity from within.
Research snapshot
Skin hydration and elasticity (human trials)
Randomised controlled trials of oral hyaluronic acid (~120 mg/day for 8â12 weeks) report improvements in skin hydration, elasticity metrics, and smoother-looking skin in adults with dry skin.

FAQs
What does TEWL mean?
TEWL stands for transepidermal water loss, which is a measure of how much water escapes through the skin. Lower TEWL is generally associated with a stronger, better-functioning skin barrier.
Can I combine HA with ceramides and vitamin C?
Yes. They support different parts of skin biology. Hyaluronic acid helps support internal hydration, ceramides support barrier lipids, and vitamin C contributes to normal collagen formation and helps protect cells from oxidative stress. This is the logic behind BOOSTâs coordinated, inside-out routine.
When should I notice a difference?
In studies, skin hydration changes are typically assessed over 4â8 weeks, with results often consolidating by 8â12 weeks. Consistent daily use matters.
