Sun protectionSPF 30 · 4 UV filtersBroad spectrum
This product offers a good level of protection against both UVB and UVA rays.
This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.
This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.
Anti-blemish3 ingredients credited for this claimStrong support
“Effaclar Duo [+] SPF 30 with Niacinamide 40ml A dual action daily mattifying moisturiser for skin prone to blemishes.”
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
Moisturizing5 ingredients credited for this claimStrong support
“A spot treatment that corrects and hydrates skin for clearer skin in 4 weeks. Now with broad spectru ... Read more”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": carnosine, 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).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
Evens skin toneNot advertised by the brand · 3 ingredients credited for this claimStrong support
This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).
Anti-agingNot advertised by the brand · 2 ingredients credited for this claimStrong support
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: carnosine.
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.
This product can also help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.
Anti-oxidationNot advertised by the brand · 1 ingredient credited for this claimStrong support
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).
ExfoliationNot advertised by the brand · 2 ingredients credited for this claimStrong support
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.

Product summary
Based on the ingredients included, we believe that "La Roche-Posay - Effaclar Duo [+] SPF 30 with Niacinamide" can offer reliable sun protection. It can protect from both UVA and UVB rays. This is great news because not all sunscreens with SPF ratings give UVA protection. (UVA rays do not cause sunburn, but still damage our skin and lead to early aging).
This product should also be hydrating enough to use without an additional moisturizer during the day. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).
