Kiehl's Midnight Botanical Concentrate, 30ml

How to use: At night, after applying lotion and serum, take one dropper onto the palm of your hand and rub it all over. The instructions say to use lotion or cream after that (it says serum oil). It felt light and blended well with my skin. I didn't feel any stickiness. There was a faint lavender scent, but it wasn't my favorite scent.

It's popular so I bought it and used up the whole bottle, but it was neither good nor bad. I didn't see any particular effect so I won't be buying it again.

It's very light. It contains calming lavender, so it can be used even when you are sensitive. It's more of an oil to prevent dryness and rough skin, rather than whitening or anti-aging. I'd like an oil that has more moisturizing power and plumpness that is more specialized for anti-aging, considering my age. It's light, so it seems like it would be very easy to use in the summer.

Nighttime beauty serum oil! It's so moisturizing and I can feel my skin getting softer. It's an oil, but it's not sticky and feels smooth, and a small amount goes a long way, so it's very cost-effective. I thought it was perfect for this dry season.

I thought it would be sticky because it's an oil-based serum, but it absorbs quickly. The next day after applying it, my skin feels moisturized. I personally don't like the scent of lavender, so I don't think I'll be buying it again.
