What the product description says

“At the heart of Effaclar K [+] is the partnership of LHA [+] and salicylic acid, which form a keratolytic action to lightly exfoliate the horny layer of skin, unblocking pores whilst preventing excess sebum from oxidising into comedones (blackheads and whiteheads).”

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: capryloyl salicylic acid, salicylic acid.

Salicylic acidKey activeEffect: HighUsed for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)~1.1–1.6%

“La Roche-Posay Toleriane Dermo-Cleanser Cleansing and Make-Up Removal Fluid gently cleanses to remove impurities and make-up, whilst hydrating the 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.

CarnosineKey active· HumectantEffect: HighA type of peptide. It attracts water to the upper layer of the skin. It can help neutralize free radicals in skin combatting the sun damage~0.35–0.75%

Zinc pcaKey active· HumectantEffect: HighA 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~1–1.5%

SarcosineKey active· HumectantEffect: HighHelps to enhance the penetration of other ingredients and attract water to the upper layer of the skin~0.8–1.2%

DimethiconeKey active· Emollient, OcclusiveEffect: HighA 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~2.7–4.1%

Cetyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~0.1–0.45%

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~0.05–0.25%

Glyceryl stearate· EmollientEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~1.7–2.6%

Octyldodecanol· EmollientEffect: LowAn emollient that helps to soften the skin and create a pleasant product texture and stabilize the formulation~3.6–5.4%

Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.15–0.55%

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.

Evens skin tone

Not advertised by the brand · 2 ingredients credited for this claim

Moderate support

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.

Capryloyl salicylic acidKey activeEffect: Medium~0.15–0.6%

Salicylic acidEffect: LowUsed for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)~1.1–1.6%
