Assalamu alikum,
What is the ruling on using skin care products with (Collagen or Hyaluronic acid) like creams and serums .
الجواب وباللہ التوفیق
Use of skin care products is allowed unless they include impermissible “haram” ingredients.
Try to find out the ingredients of your mentioned product and if those are from “halal” sources, its use will be allowed, otherwise not.
فقط واللہ اعلم بالصواب
