“Effaclar K Moisturiser For Oily Blemish-Prone Skin”
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:
carnosine, sarcosine.
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, cetyl alcohol.
Evens skin toneCapryloyl salicylic acid, Salicylic acidModerate evidence
“Hydrating, lightweight and worthy of a dermatologist's seal of approval, this blemish-blasting staple supports even-toned skin as it goes through the motions.”
This product might be able to help reduce hyperpigmentation and even out the skin tone because it contains salicylic acid. The effect, if any, is likely to be small. 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.
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: capryloyl salicylic acid.
Anti-oxidationNot advertised by the brand · Carnosine, Zinc pca + 1 moreStrong evidence
This product contains antioxidants (carnosine) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
Anti-agingNot advertised by the brand · Carnosine, Zinc pca + 1 moreModerate evidence
This product contains carnosine. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.
