Powerful-Strength Vitamin C Serum for Glow & Fine Lines

Kiehl's Powerful-Strength Vitamin C Serum for Glow & Fine Lines is a high-concentration vitamin C treatment — 12.5 percent vitamin C paired with hyaluronic acid. It is aimed at the three things that tend to show first: fine lines, uneven texture, and skin that has lost its firmness.

Skin types	Normal, dry, combination and oily
Concerns	Fine lines and wrinkles · uneven texture · loss of firmness and elasticity
Strength	12.5 percent vitamin C
Highlighted ingredients	Pure vitamin C (10%) · ascorbyl glucoside · hyaluronic acid

What it actually does

• Brings radiance up. Kiehl's says the serum visibly boosts glow — the headline reason most people reach for vitamin C.
• Softens the look of lines. Both pure vitamin C at 10% and ascorbyl glucoside are credited by the brand with reducing how visible fine lines are.
• Works on texture. Per Kiehl's, pure vitamin C also improves how skin texture appears.
• Firms the look of skin. The brand lists firmer-looking skin and smaller-looking pores among the outcomes.
• Smooths with hyaluronic acid. Hyaluronic acid is included to smooth the look of the skin alongside the vitamin C.
• Suits oily and dry skin alike. Kiehl's lists normal, dry, combination and oily as all appropriate.

How to use

1. Cleanse, then apply two pumps. Spread across the whole face and keep it away from the eye area.
2. Expect a little warmth. Kiehl's notes a warming sensation as the formula activates and blends into skin — that is normal.
3. Rinse immediately if it reaches your eyes. The brand is explicit about avoiding eye contact.
4. Build the frequency. Begin with one application a day and work up to twice — morning and night.
5. Layer SPF in the daytime. Kiehl's suggests Super Fluid UV Defense SPF 50+ (sold separately) over the top during the day.

Questions

Why does it feel warm on my face?

Kiehl's flags this in the instructions: as the serum blends in and the formula activates, you may feel warmth. It is part of how the product is described to behave, not a sign something is wrong.

Should I use it morning or night?

Kiehl's direction is both, once you have worked up to it. Start with a single daily application and gradually move to twice a day — morning and night.

Can I use it near my eyes?

No. The instructions say to avoid the eye area when applying, and to rinse immediately if any gets into the eyes.
