The REVEA CALM Barrier Support Serum is a lightweight, fragrance-free hydrating serum formulated to support skin hydration, moisture balance and everyday skin comfort.
Designed with sensitive skin in mind, the formula combines multi-weight hyaluronic acid, Pro-Vitamin B5 (Panthenol), saccharide isomerate and botanical extracts in a lightweight serum that layers easily beneath moisturiser.
These ingredients work together to help attract and retain moisture, support comfortable-feeling skin and maintain a balanced, hydrated appearance.
Below, we explore the key ingredients in the REVEA CALM Barrier Support Serum, their role in the formulation and how they support hydrated, comfortable-looking skin.
Multi-Weight Hyaluronic Acid
Hyaluronic acid is a humectant widely used in skincare to help attract and retain moisture on the skin.
The REVEA CALM Barrier Support Serum contains multiple forms of hyaluronic acid:
• Sodium Hyaluronate
• Hydrolyzed Sodium Hyaluronate
• Sodium Hyaluronate Crosspolymer
This multi-weight hyaluronic acid system forms part of the serum’s hydration-focused formulation, helping maintain moisture and support smooth, comfortable-feeling skin.
Combined with Panthenol and other humectants in the formula, it helps support everyday hydration without adding heaviness to the routine.
Pro-Vitamin B5 (Panthenol)
Panthenol, also known as Pro-Vitamin B5, is included in the REVEA CALM Barrier Support Serum to help support hydration and everyday skin comfort.
As part of the serum’s hydration-focused formula, Panthenol helps maintain moisture and contributes to softer, smoother-feeling skin.
It works alongside multi-weight hyaluronic acid and other humectants in the formula to support balanced, comfortable-feeling skin.
Saccharide Isomerate and Humectant Complex
The REVEA CALM Barrier Support Serum combines saccharide isomerate with glycerin and hyaluronic acid as part of its hydration-focused humectant system.
Saccharide isomerate is a plant-derived carbohydrate used in skincare to help attract and retain moisture, supporting hydrated and smoother-feeling skin.
Together, these humectants help maintain moisture balance and complement the serum’s multi-weight hyaluronic acid and Panthenol.
Botanical Extracts
The CALM Serum also includes several plant-derived extracts, such as:
-
Aloe Vera
-
Pomegranate Extract
-
Calendula Extract
-
Cucumber Extract
These botanical extracts complement the REVEA CALM Barrier Support Serum’s hydration-focused formula, helping support skin comfort and a refreshed, balanced appearance.
Combined with hyaluronic acid, Panthenol and the serum’s humectant complex, they form part of a lightweight formula designed for everyday hydration and comfortable-feeling skin.
