La Roche-Posay starter guide: which product to buy first

Four of the brand's best sellers, each with 15,000 to 42,000 Amazon ratings, mapped to the skin problem they actually solve.

La Roche-Posay is the French pharmacy brand dermatologists keep recommending, and on Amazon it has quietly become one of the best-reviewed skincare lines in the Premium Beauty category. The catch is that there are dozens of products with similar names. These are the four that earn their reputation, and who each one is for.

If you only buy one: Anthelios Melt-In Milk SPF 60

Most people skip sunscreen because it feels like sunscreen. Anthelios Melt-In Milk is the one that changed that. It's a broad-spectrum SPF 60 that rubs in like a light lotion, works on face and body, and is water resistant for 80 minutes. It has over 15,000 ratings at 4.6 stars, and a large share of the reviews are people who "finally found one they'll wear daily." That's the whole game with sunscreen.

If you want moisturizer and SPF in one step: Toleriane Double Repair UV

Toleriane Double Repair UV is a ceramide and niacinamide moisturizer with SPF 30 built in. It's fragrance-free and oil-free, so it works for sensitive and acne-prone skin, and it's the simplest possible morning routine: wash, apply, done. Nearly 30,000 ratings.

If your skin is dry, itchy, or eczema-prone: Lipikar AP+M Body Cream

Lipikar AP+M is the body cream in the range. Shea butter, niacinamide, and the brand's prebiotic thermal water, aimed at very dry skin and eczema flare-ups. It's accepted by the National Eczema Association and has over 42,000 ratings. People who buy it tend to buy it again, which is the review pattern you want to see from a moisturizer.

The cleanser to pair with any of them: Toleriane Hydrating Gentle Cleanser

A cream cleanser with niacinamide and ceramides that cleans without the tight, squeaky feeling. It's the default recommendation for anyone whose current face wash is making their skin worse. Nearly 40,000 ratings at 4.6 stars.

A simple routine using only these four

1. Morning: Toleriane cleanser, then Double Repair UV.
2. Before time outdoors: Anthelios Melt-In Milk on face and any exposed skin.
3. Night: Toleriane cleanser, then Lipikar AP+M on body (and on face if you're very dry).

Start with the sunscreen if you're choosing one. It's the product with the most measurable benefit, and it's the one people are most likely to stop using if it feels wrong.
