Isntree Hyper Retinol EX 1.0 Serum 20ml

Isntree Hyper Retinol EX 1.0 is a 20ml serum combining retinol at 0.1%, retinyl palmitate at 0.3% and bakuchiol at 0.6%, three forms of vitamin A activity worked into one formula. A five-ceramide complex sits in the base to support the skin barrier alongside cholesterol and phytosphingosine, with niacinamide and panthenol rounding things out. The brand's own instructions pair this with sunscreen for daytime use, which is worth following given the retinol content.

How to Use

Take 2 to 3 drops on the palm of your hands and gently pat it into your skin for maximum absorption. For daytime use, follow up with sunscreen. Use a sunscreen alongside this product during the day, since the formula includes ingredients that call for daytime sun protection.

Suitable For

Suitable for those wanting to introduce retinol gradually, thanks to the 0.1% concentration. Patch test first and start with a few nights a week rather than nightly, since retinol can cause dryness or sensitivity while skin adjusts. Use sunscreen during the day and avoid combining with other strong actives, such as exfoliating acids, on the same night at first.
