Can anyone tell me some dupes for this products? For oily skin
You could try our skincare routine builder to get you started: https://whatsinmyjar.com/skincare-routine-builder
We also have a dupes section - it may be helpful: https://whatsinmyjar.com/dupes. A good alternative to the Medik8 serum is this product with Niacinamide & other actives : https://whatsinmyjar.com/product/skin-actives-collagen-serum
I know you didn't ask about it, but I think you are missing one of the most important skincare products - a daily sunscreen ☀️.
