Is SPF 19 enough for daily sun protection?

It is fine for brief exposure like a commute or walking between buildings. For longer time outdoors, apply a dedicated SPF 30 or higher sunscreen on top.

Can I use it at night?

No. It is formulated as a daytime product with SPF; use a separate night moisturizer without sunscreen after dark.

How does it compare with the original Facial Fuel without SPF?

The original is a lighter gel-cream with no sun protection. This version adds SPF 19 and is slightly thicker, so choose it if you want one morning step.

Is it good for oily or acne-prone skin?

It is non-comedogenic and non-greasy, so it suits oily and combination skin. If you are acne-prone, patch test first because of the fragrance.

How much product is in the tube and how long does it last?

The tube holds 125 ml. With one pump or a pea-sized amount each morning, it typically lasts three to four months.

When is the best time to buy it?

Kiehl's and department stores discount it most during seasonal sales and holiday sets. Watch the price history to see whether the current price is near its low.
