"This is their retinol, which is a daily microdose serum, and this is actually a light retinol. So it's good for a beginner."

"At $65, Kiehl's micro-dose retinol has ceramides. The retinol percentage isn't disclosed, so you can assume it's probably on the lighter side. But if you have an inflamed skin barrier, you're prone to dry skin, [...] and you're trying to find other things that help with the look of crepey skin or wrinkles, it's probably one you'd want to look for."

"If you want something a little bit stronger, Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum at $65 is a gentle formula, but it's tried and true for people who use retinol. Not necessarily for beginners, but something you may want to check out."

"Kiehl's Micro-Dose Retinol is, I believe, around 0.1%, though they don't disclose it. [...] It has retinol, peptides and ceramides in it and it's a very great beginner's retinol product, the lightest one I found at Sephora."

How to Get Clear Pores from a Dermatologist! | Dr. Shereene Idriss

"Retinoids like this one by Kiehl's, which is their skin renewing daily micro dose serum, are important because they're going to help accelerate your cellular turnover of your skin cells so they don't stick together as much and they don't create the appearance of enlarged pores."

"This is for those who are more advanced in the skincare game who are not quite ready for [...] a prescription retinoid but want more from the retinol. Kiehl's is the one I would go for because it's 0.1 percent over the counter, and it has a certain type of peptide called acetyl dipeptide-1 cetyl ester, which is composed of tyrosine and arginine."

"This is going to be very hydrating. The next ingredient is niacinamide, which is a lovely combination because it strengthens the skin barrier, which is exactly what you want to do when you're using an irritating ingredient. [...] Plus, they added adenosine, which is anti-inflammatory. [...] I actually don't like a lot of products from Kiehl's, but they got it right with this particular product. I would say it's great for beginners to intermediate, but it is quite expensive at £72."

"Kiehl's is great, they make a micro-dose retinol with peptides. I like peptides because it helps signal collagen production, so you see that in the Kiehl's micro-dose Retinol Serum."

"Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum is really good if you have very sensitive skin, rosacea, and you're not sure if you can tolerate a retinol or if you're a beginner. It has a very small percentage of retinol but also has a peptide to help with anti-aging purposes. It helps with self-signaling and increasing collagen production. One pump gives you that pea-size amount, all you need there."

"This is for advanced users and the Kiehl's formula is also fabulous. The good news with Kiehl's is that you get it pretty much everywhere in the world, and it's my recommendation number five, technically affordable. This is like $30, so it is the most affordable of this entire list."

"If I wanted to use a retinol, the Kiehl's Micro Dose is enough to have an effect but it's not enough to cause any issues, so that's also a perfect beginner retinoid. It has ceramides to replenish your skin as it works."

"One of our favorite starter retinols is the Kiehl's Micro Dose Retinol, which slowly releases over time micro dose amounts of retinol so you don't get that irritation. If you're looking for a starter retinol, that's a really good place to start."
