La Roche-Posay Vitamin C Serum 12% Oil Control, 30ml

Condition: Like New. Tested and fully working with minor signs of use. One or two minor accessories missing.

The La Roche-Posay Vitamin C12 Oil Control Serum is a dermatologist-backed face serum built for oily and combination skin. It delivers 12% pure Vitamin C in a lightweight, fast-absorbing dropper formula. This 30ml serum targets dullness, visible pores, and fine lines in a single daily step. The inspection-graded bottle is full, the dropper dispenses correctly, and the serum color and texture are confirmed normal. The product insert leaflet and original bottle seal are missing — please see the product photos for full transparency.

The hero ingredient is 12% pure ascorbic acid (Vitamin C). Vitamin C is one of the most researched brightening agents in skincare. It works by inhibiting melanin production and neutralizing free radicals. La Roche-Posay uses their exclusive Vitamin C Guard Technology to stabilize this potent concentration. Stability is a known challenge with pure Vitamin C formulas. The amber glass bottle protects the formula from light degradation. This means you get consistent antioxidant potency from the first drop to the last. The serum is confirmed within its expiry date — lot number and expiry visible in the product photos.

Salicylic acid is the second key active in this serum. Salicylic acid is a beta hydroxy acid (BHA) well known for its oil-control properties. It penetrates into pores to dissolve excess sebum and dead skin cells. Regular use helps refine the appearance of enlarged pores over time. This makes the serum especially suited for oily and combination skin types. The formula dissolves on face contact for a lasting matte finish. After just two weeks, clinical testing showed improved skin tone and more radiance. After one month, skin appears less oily and pores look more refined.

Hyaluronic acid (sodium hyaluronate) is included to maintain skin hydration throughout the day. It draws moisture to the skin surface without adding oiliness or weight. This balances the exfoliating action of salicylic acid, preventing over-drying. The combined effect is a serum that brightens, controls oil, and keeps skin comfortable. Adenosine is also listed in the ingredient deck as a skin-smoothing agent. La Roche-Posay Thermal Spring Water infuses the base formula for extra soothing benefit. The texture is described as liquid, clear, and non-greasy on application. It absorbs quickly and works well under SPF in a morning routine.

This serum is dermatologist tested and suitable for sensitive, oily skin. It is non-comedogenic, allergy tested, and paraben free. The formula contains fragrance, which is disclosed on the allergy-tested label panel. La Roche-Posay recommends applying morning and evening to face and neck. The eye area should be avoided. SPF use alongside this serum is strongly recommended because Vitamin C can increase photosensitivity. Pure Vitamin C may naturally turn the formula slightly yellow on contact with air — this is a normal reaction and does not affect efficacy. The dropper bottle format allows precise, hygienic dosing with each use.

In clinical studies, 82% of users reported a visible reduction in fine lines and wrinkles. The antioxidant protection provided by 12% pure Vitamin C is long-lasting and highly effective. Skin tone appears more even and radiant within the first two weeks of consistent use. This serum is an excellent anti-aging solution for anyone dealing with oily skin concerns simultaneously. It bridges the gap between radiance-boosting and oil-control skincare. The 30ml size provides approximately one to two months of twice-daily use.

Frequently Asked Questions

Question 1: Is the serum bottle full and safe to use?

Answer 1: The fill level was inspected and confirmed full or near-full during our grading process. The dropper mechanism was tested and dispenses product correctly with each squeeze. The serum is confirmed within its printed expiry date, visible on the bottle label in the product photos.

Question 2: What accessories are missing from this listing?

Answer 2: The product insert leaflet and the original bottle shrink seal are not included with this unit. The serum bottle itself and the outer retail box are both present and in excellent shape. All functional components needed to use the serum are fully intact — nothing required for application is missing.

Question 3: Is this serum suitable for sensitive skin?

Answer 3: La Roche-Posay formulated this serum specifically to be suitable for sensitive, oily skin. It is non-comedogenic, allergy tested, and paraben free as stated on the packaging. The brand is a dermatologist partner brand focused on tolerability alongside active-ingredient efficacy.

Question 4: Why does the Vitamin C serum appear yellow or amber in color?

Answer 4: Pure Vitamin C (ascorbic acid) naturally oxidizes when exposed to air, which can cause the formula to turn a golden or amber hue over time. This color change is a normal characteristic of high-concentration pure Vitamin C formulas. La Roche-Posay confirms on the packaging that this color shift does not affect the serum's effectiveness or safety.

Question 5: How should this serum be applied for best results?

Answer 5: Apply the serum morning and evening to clean face and neck skin, avoiding the eye area. A few drops from the dropper are sufficient to cover the full face and neck. Always follow with a broad-spectrum SPF product in the morning, as Vitamin C can heighten sun sensitivity.

The La Roche-Posay Vitamin C12 Oil Control Serum sits at the intersection of brightening and oil-control skincare. Few serums combine 12% pure Vitamin C with a BHA like salicylic acid in a single lightweight formula. This makes it a standout option for oily skin types who want radiance without a greasy feel. The amber glass dropper bottle protects formula stability and makes daily dosing simple and hygienic. For anyone managing oily skin, dullness, and early signs of aging at the same time, this serum delivers meaningful multi-benefit performance.
