“Formulated with 5.5% micronized benzoyl peroxide and micro-exfoliating lipo-hydroxy acid, this acne spot treatment provides fast and visible results in less than 3 days.”
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.
“Works to unclog blocked pores and controls sebum to mattify skin and control shine. Hydrates skin for 24 hours.”
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:
glycerin, zinc pca.
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, isocetyl stearate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
“Fast absorbing and non-sticky, this anti-blemish hydrating gel-cream moisturiser is designed especially for acne-prone and sensitive skin.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
“La Roche-Posay Effaclar Duo(+) reduces the number and severity of acne blemishes, pimples, blackheads and whiteheads.”
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: capryloyl salicylic acid, zinc pca
“Active ingredients not only fight the causes of acne but also tend to the aftermath, reducing the appearance of red and brown hyper-pigmentation marks.”
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: capryloyl salicylic acid.
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.
