Shopping for a new day cream? Steer clear of those in glass jars for optimal results.
Why avoid glass jars?
Glass packaging lets light and air seep in, undermining the cream's potency and hygiene. Opt for pump bottles or tubes instead—they shield the formula from light and prevent bacterial transfer from your fingers.
Low active ingredient levels
Dr. Jetske Ultee, a renowned research doctor in cosmetic dermatology, explains that glass jar creams typically feature low concentrations of actives. Higher levels would oxidize and discolor brown over time.
