As a skincare editor who regularly tests out new serums, I’m often asked how the buzzy brand Good Molecules stacks up against drugstore favorite La Roche-Posay. While both companies aim to upgrade your skin with key ingredients, their serums take different approaches. Here’s an insider’s perspective on how these two popular formulas measure up.

Main Ingredients

The star ingredient in Good Molecules’ Niacinamide Brightening Serum is the namesake powerhouse niacinamide, a form of vitamin B3 that fades dark spots and evens tone. Meanwhile, La Roche-Posay’s Pure Vitamin C Face Serum 10 contains a high concentration of antioxidant vitamin C to brighten while smoothing fine lines. Both serums also contain hydrating hyaluronic acid and soothing botanical ingredients like aloe.

Texture and Absorption

Out of the two, Good Molecules’ serum has a slightly thicker, more viscous gel texture compared to the watery fluid consistency of La Roche-Posay’s vitamin C. Yet both serums soak right into skin, without any sticky or tacky finish. The niacinamide does leave a subtle smooth finish while the vitamin C gives a more matte result. Neither irritated my sensitive skin.

Brightening Effects

With regular use, I found both the Good Molecules and La Roche-Posay serums truly lived up to their brightening claims. The niacinamide improved my skin’s overall clarity and evenness over time. But the antioxidant vitamin C gave more immediate results in terms of reduced red marks and hyperpigmentation.

Skin Type Suitability

I would recommend both the gel-like Good Molecules serum and fluid La Roche-Posay formula to all skin types, including sensitive. Both absorbed well without provoking irritation, dryness or oiliness. Because niacinamide suits just about everyone, Good Molecules makes an especially solid choice for beginners new to serums.

Reviews and Reputation

Fans rave that the Good Molecules niacinamide serum fades stubborn discoloration better than prestige products but at a fraction of the cost. Meanwhile, La Roche-Posay garners praise for making potent pure vitamin C accessible to sensitive skin-havers. Clinical studies and awards back up both brand’s products.

Affordability

Good Molecules offers impressive effectiveness for an impressively low $6 price tag, making it a steal compared to similar niacinamide serums. And while the La Roche-Posay serum costs more at around $30, fans say a little goes a long way. Ultimately, both provide results that rival expensive spa treatments for a drugstore budget!

At the end of the day, both the Good Molecules Niacinamide Serum and La Roche-Posay Pure Vitamin C Face Serum pack a brightening punch thanks to hero ingredients backed by research. I’d choose Good Molecules for an affordable intro to smoothing and evening overall skin tone gently over time. And I’d select La Roche-Posay for those seeking fast-acting vitamin C results erasing hyperpigmentation without irritation risks. Both deliver when it comes to achieving a healthy glow on a budget!
