Which is better for acne-prone skin?

The Celimax. It is oil-free and built around calming and AC (acne care) ingredients like niacinamide and cica. The Olay is non-comedogenic but not aimed at acne.

Which is better for firming and fine lines?

The Olay. Its advanced amino-peptide complex and Hydra-firming Complex target firming and hydration. The Celimax focuses on calming and hydration instead.

Which one lasts longer?

The Olay, on volume alone: 50 ml versus 40 ml for the Celimax. How long either lasts depends on how much you use per application.

Is the Celimax worth the price?

At $19.07 to $19.90 as of early November 2026, it is a low-cost option for a calming, oil-free serum. Whether it is worth it depends on whether calming is your main concern.

Can I use either one with sensitive skin?

The Celimax is labeled suitable for sensitive skin and for all skin types. The Olay is dermatologist tested and non-comedogenic, but patch testing is still wise for reactive skin.

Can I use them together?

Yes, in principle: the Celimax in the morning for calming and the Olay at night for firming. Introduce one at a time so you can tell which product causes any reaction.
