Product summary

"L'ANZA - Keratin Healing Oil Lustrous Conditioner" is a well-rounded moisturizing product. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Urea, alanine, glycerin, glycine and magnesium pca 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). Astrocaryum murumuru seed butter, dimethicone, cetearyl alcohol, cetyl alcohol and cyclopentasiloxane in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Strong evidence

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: alanine, glycerin.

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: dimethicone, astrocaryum murumuru seed butter.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: urea

UREARole: HeroNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~0.3–0.5%

ASTROCARYUM MURUMURU SEED BUTTERRole: Key activeHelps soften the upper layer of the skin. Could be comedogenic due to the myrisic acid content~0.5–0.7%

CYCLOPENTASILOXANERole: Key activeA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~2–2.5%

DIMETHICONERole: Key activeA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~0.3–0.6%

GLYCERINRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.4–3%

GLYCINERole: Key activeHelps to attract water to the upper layer of the skin and can help restore the skin barrier function~0.25–0.45%

MAGNESIUM ASPARTATERole: Key activeMight be helpful in restoring skin barrier function and calm down inflammation in skin~0.25–0.5%

MAGNESIUM PCARole: Key activeHelps attract water to the upper layer of the skin~0.3–0.6%

MANGANESE PCARole: Key activeHelps attract water to the upper layer of the skin. Often used as a part of an ingredient complex Physiogenyl together with Sodium PCA, Magnesium PCA and Zinc PCA. The manufacturer claims that it does more than attracting water, but there is no evidence or studies supporting this claim~0.3–0.5%

SACCHARIDE HYDROLYSATERole: Key active~0.25–0.5%

SODIUM PCARole: Key activeNaturally present in skin and helps to attract water to its upper layer~0.35–0.65%

ALANINERole: Key activeAn amino-acid that helps to attract water to the upper layer of the skin and might help to lighten the skin, but solid evidence is lacking~0.25–0.45%

ZINC PCARole: Key activeA compound that combines zinc with a hydrating ingredient PCA. Might to be helpful against acne and clogged pores. Can help calm down inflammation in skin. Could be helpful in reducing the formation of free radicals in skin. Might help to reduce fine lines in wrinkles, but solid evidence is missing~0.35–0.6%
