Our ingredients · 3 min read
Ectoin appears near the end of the ingredient list for our Hydrating Day Cream, but it still deserves a clear explanation. Where does it come from, what has actually been studied, and what can those findings tell us about a finished cream?
01A protective molecule from a salty environment
In 1985, researchers first described ectoin in bacteria from the genus Ectothiorhodospira. Under certain growth conditions, these microorganisms accumulate the small molecule inside their cells, where it helps them adapt to high salt stress.
This discovery explains the biological origin of the name. It does not automatically tell us how the cosmetic raw material in a particular formula is produced today. We currently do not have approved supplier documentation for that manufacturing detail in the uprise formula.
02What research shows—and where its limits are
A randomised, double-blind study published in 2007 compared an emulsion containing 2% ectoin with the same base without ectoin and an untreated control area in 104 healthy women. The researchers measured skin hydration, surface structure and elasticity, among other parameters.
The study provides a concrete indication that ectoin can influence measurable skin properties when used in a suitable formulation. It does not prove that every product containing ectoin will have the same effect. Concentration, base formula, use and the skin being studied all differ, so we do not simply transfer the result to the uprise day cream.
03How ectoin fits into the uprise formula
In the current INCI list for the Hydrating Day Cream, ectoin appears alongside other components of the formula, including aloe vera leaf juice, glycerin, sodium hyaluronate and upcycled passion fruit extract. The cream is fragrance-free and intended for the morning.
Apply it after cleansing, either directly or after a serum. Follow with a separate sunscreen that states its SPF. If your current moisturiser already works well for you, ectoin alone is not a reason to make your routine unnecessarily bigger.
04A simple way to choose
Looking for a moisturiser for the morning? The Hydrating Day Cream is the direct uprise starting point. If you then want to add a serum, choose between the Balancing Multi Vitamin Drops and the Calming Serum. Introduce new products one at a time so you can judge how your skin feels more easily.
