Product summary

"Obagi - Nu-Derm Clear Fx" could be helpful for: Evens skin tone and Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

This product contains acids (lactic acid 1.20% - 1.90%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). Lactic acid is particularly good in attracting water to the upper layer of the skin and improving the skin barrier.
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 product it is used for stabilizing other ingredients in the formulation. In this concentration (0.55% - 1.35%) it cannot have a noticeable benefit for the skin.
Humectants (glycerin 2.70% - 4.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: arbutin.

arbutin 5.9% - 8.9%

Irritation risk:

Concentration: Effectiveness: MEDIUM

Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin

lactic acid 1.2% - 1.9%

Irritation risk:

Concentration: Insufficient!

An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)

ascorbic acid 0.55% - 1.35%

Irritation risk:

Concentration: Insufficient!

The 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

Moisturizing

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

glycerin 2.7% - 4.1%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

cetyl alcohol 3.5% - 5.2%

Irritation risk:

Concentration: Effectiveness: MEDIUM

A non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together

lactic acid 1.2% - 1.9%

Irritation risk:

Concentration: Insufficient!

Anti-oxidation

This product contains antioxidants (arbutin) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

arbutin 5.9% - 8.9%

Irritation risk:

Concentration: Effectiveness: MEDIUM

Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin

ascorbic acid 0.55% - 1.35%

Irritation risk:

Concentration: Insufficient!

The 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

tocopheryl acetate 0.85% - 1.3%

Irritation risk:

Concentration: Insufficient!

A 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.
