Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!
Learn more about WaterLa Roche-Posay Retinol B3 Serum contains this as ingredient number 1.
Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 1.
Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 2.
Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.
This property also makes Pentylene Glycol a great texture enhancer. It can help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.
Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.
Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.
Learn more about Pentylene GlycolLa Roche-Posay Retinol B3 Serum contains this as ingredient number 5.
Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 4.
Niacinamide has emerged as an all-star ingredient due to its many benefits.
It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 5.
Glycine Soja Oil comes from the soybean. Glycine Soja is native to eastern Asia.
Soybean oil is an emollient. It is rich in antioxidants and fatty acids including palmitic, stearic, oleic, and linoleic acids.
As an emollient, the fatty acids in soybean oil helps keep your skin soft and hydrated. It does so by creating a film on top that traps moisture in.
Soybean oil is also rich in vitamin E, a potent antioxidant. Vitamin E is also anti-inflammatory and provides a soothing effect.
Studies show soy may help fade hyperpigmentation from UVB. It does so by disrupting the melanin process from UVB induced skin inflammation.
This ingredient may not be malassezia folliculitis, or fungal-acne, safe.
Soybeans are rich in proteins and are part of the legume family. Foods made with soybeans include tofu, soymilk, edamame, miso, and soy sauce.

Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 32.
Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:

Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 20.
Retinol is a form of Vitamin A and proven to help with anti-aging.
It promotes collagen production, increases new cell turnoever, and protects your skin as an antioxidant.
Retinol boosts collagen production and increases cell turnover. This makes retinol effective in removing wrinkles, fading dark spots, and reducing the appearance of pores.
Retinol is less effective when exposed to sun. Be sure to look for appropriate packaging to keep your retinol potent.
Using retinol and retinoids will increase sun-sensitivity in the first few weeks of use. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.
We recommend speaking with a medical professional about using this ingredient during pregnancy.
Retinol may cause irritation in some people, so be sure to patch test. Experts recommend 'ramping up' retinol use: start using this ingredient once a week and work up to using it daily.

Adenosine is in every living organism. It is one of four components in nucleic acids that helps store our DNA.
Adenosine has many benefits when used. These benefits include hydrating the skin, smoothing skin, and reducing wrinkles. Once applied, adenosine increases collagen production. It also helps with improving firmness and tissue repair.
Studies have found adenosine may also help with wound healing.
In skincare products, Adenosine is usually derived from yeast.

Ammonium Polyacryloyldimethyl Taurate is a polymer made from ammonium salts. It helps add stability and texture to a product.
Ammonium Polyacryloyldimethyl Taurate is stable over a wide pH range. Due to its ability to absorb water, it can help thicken the texture of a product.
As an emulsion stabilizer, this ingredient is able to stabilize and mix the other ingredients. This creates a consistent texture.

Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 26.
Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.

Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 28.
Trisodium Ethylenediamine Disuccinate is used to help stabilize a product.
It is a chelating agent, meaning it helps prevent metal ions from binding to other ingredients. This prevents unwanted reactions in products. Metal ions can come into a product via the water ingredient. They are found in trace amounts and are not known to be harmful.
La Roche-Posay Retinol B3 Serum contains this as ingredient number 16.
Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 22.
Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

Kiehl's Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide contains this as ingredient number 24.
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
La Roche-Posay Retinol B3 Serum contains this as ingredient number 21.

Very good and gentle retinol serum
My retinol journey began with this gentle serum with a concentration of 0.3% retinol: 0.1% pure retinol combined with 0.2% retinol palmitate that ensures gradual release of the active ingredients. It din't irritate my skin or cause any major break-outs, just some slight purging in the beginning, but that is concidered a normal reaktion that fades as soon as the skin gets used to it. I recommend it for retinol beginners and people with sensitive skin. [Edited]

Great retinol for beginners
This is a product with a low dose of retinol, which makes the product suited to apply in the eye area as well. A lot of my earlier products containing retinol were serums, while this is more of a cream. It makes it more hydrating, but without an additional moisturiser it is still drying me out.
Although the percentage of retinol is low, your skin has to adjust to the retinol, using it every other day. Combining it with a moisturiser and a good hydration serum in the morning makes this a great product for your skin.
I highly recommend combining this with Missha Time Revolution Night Repair. It did wonders for my skin!
