Does Ksisters Iwlt Protecting Base Sun Cream leave a white cast?
No, white cast is rated low. It dries to a matte finish and absorbs without a noticeable residue, so it generally works well under makeup and on most skin tones.
Is the Ksisters Iwlt Protecting Base Sun Cream good for oily or acne-prone skin?
Yes, it is a reasonable match. It has a matte finish, stays lightweight and is rated low for breakout-triggering ingredients, which commonly suits oily and blemish-prone skin.
Is it mineral or chemical?
It is a chemical-led formula that also contains some mineral filters. It pairs older chemical filters with zinc oxide and titanium dioxide.
