Take the skin testUnleash the power of youthful skin with the Isntree Hyper Retinol EX 1.0 Serum, a high-performance well-aging solution designed to combat the visible signs of aging. Boasting an impressive 1% retinol, along with 0.3% retinyl palmitate and 0.6% bakuchiol, this serum is a potent ally in reducing fine lines and wrinkles. Infused with five types of peptides and ceramides, it ensures optimal hydration, while TECA tackles inflammation for a comprehensive skincare approach.
Hyper Retinol EX 1.0 Serum is a cushioning serum from Isntree. The formula is built mainly around hydration. The ingredient list runs to 42 ingredients, each broken down in full below.
By its ingredient list the formula reads as moderately cushioned — emollient enough to feel like a cream, without the heaviest occlusives near the top. Hydration is handled by Butylene Glycol, Glycerin and Betaine, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: Very high. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Glycerin, Betaine and Panthenol.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Allantoin, Panthenol, Asiaticoside and Niacinamide.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide, Hydrogenated Lecithin, Panthenol and Ceramide NP.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Bakuchiol and Tocopherol.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
It can be used morning and evening. In a routine it goes before moisturiser. Tap along the orbital bone with your ring finger; product migrates upward on its own.

Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
