“Dehydrated skin isn’t simply a lack of moisturiser.It reflects disruption to the skin barrier and the mechanisms that retain water within the skin.”
— Dr Garry, Rejuvaus Founder & Formulation Director —
DEHYDRATION DOESN’T ONLY AFFECT DRY SKIN
Dehydration can affect any skin type including oily and combination skin. When the skin loses its ability to retain water, it can appear:
Dull or tired
Tight or uncomfortable
Rough or uneven in texture
More prone to irritation
Fine lines appear more noticeable
Environmental exposure, heating, air conditioning, harsh skincare and lifestyle factors can all disrupt the skin’s natural hydration balance.
Hydration is not only about applying moisture to the surface. The skin must also maintain the structures that hold water inside.
A MULTI-PATHWAY SYSTEM FOR SKIN HYDRATION
Rejuvaus formulas support several biological pathways involved in hydration and barrier health. Rather than relying on a single moisturising ingredient, the system works by restoring the skin’s ability to retain moisture over time.
Key support pathways include:
Water retention and hydration balance
Skin barrier repair and lipid replenishment
Cellular renewal for smoother texture
Inflammation reduction and skin comfort
Structural support for healthier skin resilience

STEP 1: CLEANSER
STEP 2: SERUMS
STEP 3: SPF + MOISTURISER
WHY SKIN BECOMES DEHYDRATED
Several biological systems influence the skin’s hydration levels.
WATER RETENTION & HYALURONIC ACID
Hyaluronic acid naturally helps the skin retain water within the dermis. Low molecular weight forms help attract water deeper into the skin, improving hydration and elasticity. Rejuvaus combines advanced hyaluronic acid with lipid-supporting ingredients to improve hydration balance.
What you’ll notice over time
Plumper looking skin
Improved elasticity
Less tightness or discomfort
BARRIER REPAIR & LIPID SUPPORT
The skin barrier is made of lipids, ceramides and structural proteins that prevent moisture loss. When this barrier weakens, water escapes more easily. Ingredients such as ceramides, peptides and the L22 lipid complex help restore barrier integrity.
What you’ll notice over time
Reduced moisture loss
Improved skin softness
Stronger barrier resilience
CELLULAR RENEWAL
Dehydrated skin often accumulates surface buildup that prevents moisture from penetrating effectively. Controlled exfoliation and renewal help improve ingredient absorption. Encapsulated actives allow gentle renewal without disrupting the barrier.
What you’ll notice over time
Smoother skin texture
Improved hydration penetration
More luminous skin
ENVIRONMENTAL DEFENCE
UV exposure and pollution increase oxidative stress and weaken the skin barrier. Daily mineral sun protection helps maintain hydration levels while preventing environmental damage.
What you’ll notice over time
Improved skin stability
Reduced dehydration triggers
Healthier skin resilience
What Our Customers Are Saying
Progressive improvements in skin comfort, hydration and resilience.
“In practice, dehydrated skin improves most consistently when hydration is supported alongside barrier repair and renewal.Simply applying moisturiser alone rarely restores long-term skin balance.”

COMMON QUESTIONS ABOUT DEHYDRATED SKIN
What causes dehydrated skin?
Dehydrated skin occurs when the skin loses water faster than it can retain it. Common causes include environmental exposure, harsh skincare products, low humidity, sun exposure and barrier disruption.
What is the difference between dry skin and dehydrated skin?
Dry skin lacks oil, while dehydrated skin lacks water. Dehydration can occur in any skin type, including oily skin. Supporting hydration and barrier repair helps restore balance.
Which ingredients help reduce redness?
Several ingredients help improve skin hydration: • Hyaluronic acid • Ceramides • Peptides • Niacinamide • Lipid complexes
Rejuvaus formulas combine these ingredients to support both hydration and barrier health.
Is hyaluronic acid good for dehydrated skin?
Yes. Hyaluronic acid helps attract and retain water in the skin. Low molecular weight hyaluronic acid penetrates deeper layers to improve hydration and elasticity.
Why does dehydrated skin show fine lines?
When skin loses water, it becomes less plump. This can make fine lines and texture appear more noticeable. Improving hydration helps restore smoother looking skin.
How long does it take to improve dehydrated skin?
Many people notice improvements in hydration and comfort within several weeks. Long-term improvements occur when hydration, barrier repair and renewal are supported consistently.
