As a skincare editor who tests countless serums, I’m often asked how buzzy budget-friendly brand The Inkey List stacks up against French pharmacy favorite La Roche-Posay. While both companies offer effective formulas powered by proven ingredients, they take different approaches. Here’s my take on how these popular serums compare after trying them firsthand.

Star Ingredients

The star ingredient in The Inkey List’s Hyaluronic Acid Serum is hydrating hero hyaluronic acid to tackle dehydration, the root of most skin issues. Meanwhile, La Roche-Posay’s Pure Vitamin C Face Serum 10 spotlights a concentrated 10% vitamin C derivative to even skin tone and target aging concerns like fine lines. Both serums also rely on soothing botanical extracts.

Texture and Absorption

Out of the two formulas, The Inkey List serum features a thicker gel-like consistency compared to the thin, fluid viscosity of the La Roche-Posay vitamin C. Yet both serums absorb rapidly without any sticky residue leftover. The hyaluronic acid does leave skin with a subtle bounce-back hydration, while the vitamin C serum dries to a smoother matte finish.

Effectiveness

With regular use, I found both the Inkey List HA and La Roche-Posay vitamin C serums live up to their claims. The hyaluronic acid boosted moisture for bouncier, plumper-looking skin over time. But the antioxidant vitamin C worked faster at improving skin tone, fading slight pigmentation and early fine lines in just a few weeks.

Skin Type Suitability

The rich Inkey List HA serum works well for normal to very dry skin types needing an extra hydration punch. Oilier or acne-prone complexions would likely prefer the lightweight La Roche-Posay vitamin C serum instead as it won’t feel heavy or clog pores while still perfecting skin’s texture.

Reviews and Reputation

The Inkey List garners glowing reviews for offering effective “no-frills” formulas solving skin concerns without fancy fillers at very wallet-friendly prices. Meanwhile, La Roche-Posay products like their vitamin C enjoy immense trust and loyalty for elegantly-formulated dermatologist-approved treatments compatible with sensitive types.

Affordability

With most products ring up under $15, The Inkey List takes the cake when it comes to budget-friendly skin solutions that actually work and skip marketing fluff. Still, La Roche-Posay manages to offer accessible pricing under $30 for their medically-proven formulas. Both give prestige brands at higher price points a true run for their money!

At the end of the day, those hoping to target wrinkles and pigmentation can count on the La Roche-Posay Pure Vitamin C Serum for fast-acting brightening. For plumping hydration on a budget, grab The Inkey List’s straight-to-the-point Hyaluronic Acid to quench thirsty skin. Both deserve a permanent spot on your shelf!
