Isostearyl Isostearate
Can worsen Oily Skin
These ingredients are known to potentially contribute to excess oil or shine, but they don't affect everyone the same way. Skin can be oily for many reasons, so it's always a good idea to consider your unique skin needs when choosing products.
May cause Acne
These ingredients have a higher likelihood of clogging pores or triggering breakouts, especially for acne-prone skin. However, skin reactions are individual - what causes breakouts for one person may work fine for another. Patch test if you're concerned.
May feed Fungal Acne
Fungal acne-safe products avoid ingredients that feed Malassezia yeast, the cause of fungal acne. Unlike regular acne, fungal acne appears as small, uniform bumps and won't respond to typical acne treatments. If you suspect fungal acne, consult a dermatologist for proper diagnosis.
