La Roche-Posay Vitamin C Serum 12% with Hyaluronic Acid, 1.01 fl oz — Brightening, Lightweight for Oily/Combination Skin

La Roche-Posay Pure 12% Vitamin C Serum is a fast-absorbing, dermatologist-tested face serum formulated to boost radiance, help refine pores, and rebalance oily skin while delivering antioxidant protection.

This lightweight serum combines 12% pure vitamin C stabilized by Vitamin C Guard technology with salicylic acid and hyaluronic acid to address dullness, uneven tone, and texture without a heavy finish. The liquid texture was developed for oily and combination skin — it absorbs quickly, won’t clog pores, and is non-comedogenic and allergy-tested. Clinical and consumer studies reported visible brightening and reduced appearance of fine lines when used twice daily for several weeks.

How does this serum improve skin radiance and tone?

The concentrated 12% pure vitamin C works as an antioxidant to brighten skin and even out discoloration. Stabilization technology helps preserve potency so the active ingredient remains effective over time. Regular application supports a more luminous, balanced complexion.

• 12% pure vitamin C for noticeable brightening
• Vitamin C Guard technology to maintain stability and efficacy
• Lightweight, fast-absorbing base that layers under moisturizers and SPF

Will it help oily or pore-prone skin without causing breakouts?

Yes — the formula includes salicylic acid to gently exfoliate inside pores and help control excess oil. Its non-comedogenic formulation and fast-absorbing liquid texture reduce the risk of residue that can cause congestion. Dermatologist testing and allergy testing further support tolerance for sensitive, oily skin types.

• Salicylic acid refines pore appearance and clears buildup
• Non-comedogenic, lightweight texture for oily/combination skin
• Suitable for sensitive skin thanks to dermatological and allergy assessments

How does the serum target fine lines and aging signs?

Concentrated vitamin C helps support the skin’s appearance by brightening and smoothing texture, while hyaluronic acid hydrates to plump fine lines temporarily. Consumer studies reported a visible reduction in the appearance of wrinkles after consistent use. Results are gradual and improve with ongoing application.

• Vitamin C addresses dullness and texture associated with aging
• Hyaluronic acid provides lightweight hydration and immediate plumping
• Observed reduction in wrinkle appearance in consumer testing with regular use

How should I incorporate this serum into my routine safely?

Apply a few drops to cleansed skin once or twice daily, then follow with moisturizer and broad-spectrum SPF in the morning. Because pure vitamin C can oxidize and turn yellow over time, store the bottle upright away from direct heat or light to preserve freshness. If you have very sensitive skin, introduce the serum gradually and patch-test first.

• Use on cleansed skin, morning and/or evening as tolerated
• Follow with moisturizer; always apply sunscreen during daytime use
• Store cool and upright to slow oxidation of vitamin C

Who is this for: This serum is aimed at people with oily, combination, or sensitive skin who want visible brightening, pore refinement, and a lighter anti-aging step in their routine. It suits users seeking a stable, high-concentration vitamin C formula that layers well under moisturizers and sunscreen. If you prefer richer, oil-based serums or have active rosacea, consult a dermatologist before starting a new vitamin C product.
