What the product description says

“Vitamin C Radiance Moisturizer”

From product name

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: glycerin, hyaluronic acid.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide ap, ceramide eop, ceramide ng, ceramide np, phytosphingosine, tetrapeptide-21

What the product description says

“Velvety-smooth moisturizer delivers powerful hydration and improves skin tone for a radiant, even complexion. Maintains skin’s barrier function. Instantly absorbs for a healthy glow.”

Source: N/A

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinol.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: resveratrol.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

RetinolHeroEffect: HighTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating~0.4–0.6%

ResveratrolEffect: LowHelps neutralize free radicals in skin and might help reduce fine lines and wrinkles, as well as even out the skin tone~0.3–0.55%

Tetrahexyldecyl ascorbateUnder-dosedEffect: HighBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.~0.65–1%

Ascorbic acidUnder-dosedEffect: HighThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.55–0.8%

This product contains antioxidants (resveratrol, retinol) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

ResveratrolKey activeEffect: HighHelps neutralize free radicals in skin and might help reduce fine lines and wrinkles, as well as even out the skin tone~0.3–0.55%

RetinolKey activeEffect: HighTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating~0.4–0.6%

CaffeineEffect: LowMight be helpful in neutralizing free radicals. Can have a dehydration effect that might somewhat decrease the look of puffy eyes~0.2–0.35%

TocopherolUnder-dosedEffect: HighPure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.2–0.4%

Sodium ascorbyl phosphateUnder-dosedEffect: MediumA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~0.95–1.15%

BisabololEffect: Low, below effective doseAn active component of chamomile plant that historically has been used to calm down irritated skin. A recent study shows that bisabolol indeed can have some anti-inflammatory effect on skin, even though conclusive data is lacking. Bisabolol has a sweet floral scent and can be added to products for its aromatic properties~0.15–0.3%

Tocopheryl acetateEffect: Low, below effective doseA more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.~0.2–0.4%

Anti-aging

Not advertised by the brand · 10 ingredients credited for this claim

Strong support

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinol.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl tripeptide-28, resveratrol, tetrapeptide-21.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Tetrapeptide-21Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.2–0.35%

Product summary

Based on the ingredients included, "OAM - Vitamin C Radiance Moisturizer" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. OAM - Vitamin C Radiance Moisturizer ticks this box. Glycerin, hyaluronic acid, sodium hyaluronate, sodium pca and butylene glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (ceramide eop, ceramide ng, ceramide np, phytosphingosine and cholesterol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this moisturizer it is used for stabilizing other ingredients in the formulation. In this concentration (0.55% - 0.80%) it cannot have a noticeable benefit for the skin.
This moisturizer contains an effective form of Retinoids (vitamin A): retinol 0.40% - 0.60%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily. Because of the irritation risk of Retinoids, we recommend to have another, retinoid-free moisturizer in your routine to use on the alternate days or when your skin feels dry.
Another benefit is that this moisturizer contain ceramides (phytosphingosine 0.25% - 0.45%, ceramide eop 0.20% - 0.40%, ceramide ap 0.20% - 0.40%, ceramide np 0.25% - 0.50% and ceramide ng 0.30% - 0.50%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
We like that this moisturizer contains peptides (tetrapeptide-21 0.20% - 0.35%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: lecithin, vitamin e, niacinamide, vitamin c, tetrahexyldecyl ascorbate and sodium ascorbyl phosphate
