The Science Behind the Spritz: Why Most Hydration Mists Fail
Most hydration mists are around 90% water, a dash of fragrance, and a splash of marketing. Water on its own evaporates within minutes, and on reactive skin that evaporation can leave you tighter than you started. That's not a hydration problem. It's an architecture problem.
TrueOfBlue is built around three layers that work as a system. Glycerin and polyglutamic acid pull water in. A glyceryl acrylate film former lays it down in an invisible layer that doesn't disappear when the air gets dry. Niacinamide and panthenol comfort underneath. Every ingredient is on the bottle. The pH is 5.0, on purpose.
- Polyglutamic acid: a humectant that holds many times its weight in water
- Glycerin and panthenol: the two most-studied humectants in modern dermatology
- Glyceryl acrylate film former: keeps hydration on skin instead of in the air
- Niacinamide at sensitive-skin levels with the pH locked at 5.0
"I read INCIs before I buy anything. Most hydration mists fall apart under that scrutiny because the active list is short and the fragrance list is long. This one's the opposite. That's why I tried it. The way it feels is why I kept it."

Why These Ingredients and No Others
Discover the ingredients built to work on real skin with real problems.
Polyglutamic Acid (PGA)
A biopolymer that holds many times its weight in water, far more than hyaluronic acid. PGA forms an invisible film on the skin's surface that pulls hydration in and helps it stay there instead of evaporating into dry air.
""γ-PGA enhanced hyaluronic acid synthesis and promoted aquaporin 3 expression, which is involved in skin hydration. Topical application of 1% γ-PGA elevated filaggrin, involucrin, CD44, and aquaporin 3 expression." Ko et al., International Journal of Molecular Sciences, 2025"

Niacinamide
The most-studied skincare active in modern dermatology. Nicotinamide is a form of vitamin B3 that supports the look and feel of more even, comfortable, hydrated skin. Tolerated at sensitive-skin levels, even on reactive complexions.
""Nicotinamide improved the permeability barrier by stimulating de novo synthesis of ceramides, with upregulation of serine palmitoyltransferase and other intercellular lipids." Tanno et al., British Journal of Dermatology, 2000"

Panthenol (Pro-Vitamin B5)
A long-trusted humectant that converts to vitamin B5 once it's on your skin. Panthenol helps skin feel softer, smoother, and less tight, and pairs naturally with the rest of the humectant stack to support layered hydration.
""Topical application of dexpanthenol-containing emulsions statistically significantly improved stratum corneum hydration and skin barrier function compared with control." Proksch et al., Journal of Dermatological Treatment, 2017"

Glycerin
The most-studied humectant in dermatology. Glycerin pulls water into the upper layer of your skin and holds it there, which is why it's a foundational ingredient in nearly every sensitive-skin formula made today.
""Glycerol, a well-known cosmetic ingredient, exists in the stratum corneum as a natural endogenous humectant." Verdier-Sévrain & Bonté, Journal of Cosmetic Dermatology, 2007"
