I was invited to try on the Kiehl's Powerful Strength Line-Reducing Concentrate and it's been amazing!
How I've been using it: 1.5-2 pumps on the palm.
4 steps for the night (cleanse, tone, serum, moisturize)
and
5 steps for the day (cleanse, tone, serum, moisturize, sunblock)
...and that's a v-log of it.
