Finally...Something that does what it says!!
I received the Line reducing concentrate as a gift and I must say, its one of my most treasured beauty products. After the first few days the tone and texture of my skin had a noticeable improvement. I have some discoloration on my forehead, right at the hairline, from sun worship that has faded dra...

BEWARE OF THE NEW 3.4 OZ SIZE BOTTLE

The vitamin C serum goes on smooth and not sticky at all. I use it first in AM & PM before other products. I can tell a difference in my skin after just a week.

This stuff is crazy powerful. I saw results within a week. Does this mean I have to use it forever? What happens if I miss a couple days by accident?
My go-to Vitamin C Serum

I LOVE this product and have been a loyal buyer for years. It is a great deal for the price, and last a long time. I've seen results - skin brightening, redness reduction after consistent, daily use. I sometimes find Vitamin C Serums to be sticky, and I am also prone to spilling them. This product is not sticky, and does not leave my skin feeling heavy or oily. Also, it's spill proof. LOVE.LOVE.LOVE.

I have dry, sensitive skin and have always been wary of vitamin C serums. But Kiehl's Powerful Strength Vitamin C Serum changed everything. It's gentle, hydrating, and actually delivers results. The blend of vitamin C and hyaluronic acid leaves my skin bright, plump, and radiant. Plus, its stable formula ensures potency without irritation. And as a bonus, it works as a fantastic primer before makeup. If you struggle with sensitive skin like me, this serum is a must-try.
