Take the skin testVisibly correct imperfections with the La Roche-Posay Effaclar Duo+ SPF30; a non-sticky formula that works to reduce the appearance of blemishes and reveal a refined complexion. Ideal for oily and blemish-prone skin types, the correcting formula penetrates and clears blocked pores in order to visibly reduce blackheads and other impurities.
Effaclar Duo+ SPF30 with Niacinamide is a lightweight skincare product from La Roche-Posay, a brand based in France. It is rated SPF 30. Its job is UV protection, with the rest of the formula working on hydration. The ingredient list runs to 27 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Silicones in the formula tend to give a smooth, blurred finish and help it grip under makeup. Hydration is handled by Glycerin, Water and Dimethicone, humectants that pull water into the upper layers of skin rather than sealing it there.
It is a chemical (organic-filter) sunscreen, using Octocrylene, Homosalate, Octisalate and Avobenzone. Between them those filters cover UVB, UVA II and UVA I, so the formula is broad-spectrum in the meaningful sense: it reaches past 340 nm, where the ageing wavelengths sit. The formula contains a photounstable filter alongside a stabiliser, which is the standard and effective way to keep it from degrading in sunlight.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Glycerin, Water, Dimethicone and Diisopropyl Sebacate.
Oil control: Moderate. Ingredients that moderate sebum or absorb shine, and here that comes from Niacinamide, Zinc PCA, Capryloyl Salicylic Acid and Salicylic Acid.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Ppg-2/peg-8 Cocoate, Sucrose Cocoate, Niacinamide and Capryloyl Salicylic Acid.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it. One ingredient on the label has not been matched to our database yet, so the analysis above reads a slightly incomplete list.
It does contain drying alcohol, worth knowing if your skin reacts to any of them.
It can be used morning and evening. In a routine it goes after serums. Seal in your serums with it; in the morning, sunscreen still goes on top. It carries UV filters, so it belongs in your morning routine.

Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Attracts and locks in moisture to keep skin plump and dewy
Targets breakouts by reducing bacteria and unclogging pores
Helps unclog pores and reduce blackheads for clearer skin
Calms redness, irritation, and inflammation for sensitive skin
Tightens and refines the look of enlarged pores
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.
Chemical (organic) filter system · broad-spectrum through UVA I
Mostly present to stabilise avobenzone rather than for its own modest UVB coverage. Degrades slowly into benzophenone over a product's shelf life.
Another solvent-filter: modest UVB coverage, mostly there to carry other filters.
A weak filter used mainly as a solvent — it dissolves the crystalline filters (avobenzone, oxybenzone) so they can be formulated at all.
The workhorse UVA filter, and the fragile one: it loses a large share of its protection within an hour of sun unless the formula pairs it with a stabiliser such as octocrylene or Tinosorb S.

Judged on how rich the formula reads from its ingredient list, it suits Balanced skin best. It is the least natural fit for Dry, Combination (dry) skin.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
3 ingredients could feed malassezia: Sorbitan Stearate, Ppg-2/peg-8 Cocoate, Sucrose Cocoate. That describes the yeast's food supply, not a prediction that they will cause a breakout.
It contains Salicylic Acid, which are usually reviewed with a doctor during pregnancy. Ask your doctor or midwife before using it.
Yes — it contains Alcohol Denat..
No — it contains Dimethicone, Peg-10 Dimethicone/vinyl Dimethicone Crosspolymer.
It layers well with Azelaic acid, Copper peptides, Bakuchiol, Niacinamide, Hyaluronic acid, Ceramides. Take more care combining it with Retinoids (retinol, retinal), Vitamin C (L-ascorbic acid), AHAs (glycolic, lactic), BHA (salicylic acid), PHAs (gluconolactone), Benzoyl peroxide — use them in separate routines or on alternate days.
Use it morning and evening, after serums.
It lists 27 ingredients, of which 6 are recorded as actives.
La Roche-Posay, a brand based in France.
It filters UV with Octocrylene (octocrylene), Homosalate (homosalate), Octisalate (ethylhexyl salicylate), Avobenzone (butyl methoxydibenzoylmethane).
Yes. Its filters cover UVB, UVA II and UVA I, so protection reaches past 340 nm into the deep-UVA range associated with ageing and pigmentation.
Unlikely. It filters with organic (chemical) filters only, which dissolve into the formula rather than sitting on the surface, so they do not leave a white cast.
It contains none of the filters named in the Hawaii and Key West reef legislation (oxybenzone and octinoxate). "Reef safe" is not a regulated term, so treat that as a fact about the filter list rather than a certification.
Yes. Let it set for a couple of minutes before foundation so it does not pill, and reapply over makeup with a stick or powder rather than rubbing more in.
Every two hours of sun exposure, and immediately after swimming, sweating heavily or towelling off.
