Which is better for dark spots?

The Olay. It combines vitamin C, AHA and niacinamide, which target uneven tone. The Kiehl's has no brightening actives.

Which suits sensitive skin?

The Kiehl's. It is fragrance-free and has no exfoliating acids. The Olay's AHA and retinol can sting sensitive skin.

Yes. Use the Olay in the morning and the Kiehl's at night. Introduce the Olay slowly, a few times a week, to limit irritation.

Which lasts longer per jar?

The Kiehl's bottle is the simpler daily moisturizer, so it is easier to use up steadily. The Olay is a 50 ml jar used once daily, so it lasts about two months at normal use.

Is the Olay worth it over the Kiehl's?

Only if you want active brightening and anti-aging ingredients. If you just need hydration, the Kiehl's does that with less irritation risk.

Which is better for dry skin?

The Olay is marketed for dry skin and pairs hyaluronic acid with its actives. The Kiehl's suits all skin types, so very dry skin may want a richer cream on top.

Olay Regenerist Vitamin C + AHA Day Cream Gel vs Kiehl's Ultra Facial Moisturizer

Buy the Olay Regenerist Vitamin C + AHA 24 Day Cream Gel if you want an exfoliating, brightening day cream aimed at dullness, dark spots and fine lines. Buy the Kiehl's Ultra Facial Moisturizer if you want a plain, fragrance-free barrier moisturizer that suits most skin types and works for sensitive skin. The Olay is the more active formula; the Kiehl's is the safer, simpler one.
