What the product description says

“Control Essence”

From product name

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

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.3–2.8%

BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~1.4–1.7%

Glucosyl hesperidinKey active· HumectantEffect: MediumMight be able to neutralize free radicals in skin. Also works as a humectant~0.95–1.15%

CyanocobalaminKey activeEffect: HighCan support skin barrier function and reduce inflammation in skin~0.3–0.6%

Hydrolyzed hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin~0.3–0.5%

Glycine soja seed extractKey active· EmollientEffect: MediumAn emollient that helps soften the skin. Might be somewhat helpful in evening the skin tone.~0.25–0.45%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.2–0.4%

ChitosanKey active· HumectantEffect: MediumInhibits acne-causing bacteria on the surface of the skin. Can help to reduce inflammation caused by bacteria. Helps neutralize free radicals in skin. Helps to attract water to the upper layer of the skin~0.2–0.4%

Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~5.8–7.1%

Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~4.2–5.2%

AlginEffect: LowUsed to thicken product formulation. Can help attract water to the upper layer of the skin~0.1–0.2%

Lactic acidUnder-dosedAn 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)~0.2–0.35%

Anti-oxidation

Not advertised by the brand · Chitosan, Glucosyl hesperidin + 6 more

May help

This product contains antioxidants (chitosan) 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.

Glycine soja seed extractEffect: LowAn emollient that helps soften the skin. Might be somewhat helpful in evening the skin tone.~0.25–0.45%

Magnesium ascorbyl phosphateEffect: Low, below effective doseA derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high~3–3.6%

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.~0.45–0.65%

Rosmarinus officinalis leaf extractEffect: Low, below effective doseCan be helpful in reducing inflammation in skin, including inflamed acne. It can be irritating~0.15–0.3%

Evens skin tone

Not advertised by the brand · Retinyl palmitate, Glycine soja seed extract + 2 more

May help

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: glycine soja seed extract, retinyl palmitate.

Retinyl palmitateKey activeEffect: MediumThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~1.2–1.4%

Product summary

"Dr. K - Control Essence" could be helpful for: Moisturizing, Evens skin tone, Anti-blemish and Anti-aging, but its actives are not the most effective or are not well-studied.

Ingredient callouts

this product includes a form of Retinoids (vitamin A) - retinyl palmitate 1.20% - 1.40%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
Humectants (sodium hyaluronate 0.20% - 0.40%, hydrolyzed hyaluronic acid 0.30% - 0.50%, betaine 1.40% - 1.70% and glycerin 2.30% - 2.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
