Trust & Pharmacist Advice Vitamin C can be a useful addition to a morning skincare routine where dullness, uneven-looking skin tone, fine lines or early signs of ageing are the main concerns. From a pharmacy skincare perspective: This is a relatively concentrated vitamin C serum, containing 12% pure ascorbic acid. Introduce it gradually if you have particularly reactive or sensitive skin. Apply to clean, dry skin before moisturiser. Vitamin C is an antioxidant skincare ingredient and works particularly well within a morning routine followed by sunscreen. Salicylic acid is also present, so consider your complete skincare routine before combining multiple exfoliating products. If you already use a separate AHA/BHA exfoliant, strong retinoid or intensive blemish treatment, avoid introducing several active products simultaneously. Mild initial awareness of an active formula can occur, but persistent burning, redness, itching or peeling is a reason to stop using it. The serum contains alcohol denat. and fragrance, which may be relevant for particularly reactive skin. Vitamin C formulas can naturally change in colour over time. Keep the product properly closed and stored according to the manufacturer's instructions. Use broad-spectrum sunscreen every morning as part of your overall skincare routine. Persistent pigmentation, rapidly changing skin lesions or unexplained skin changes should be assessed appropriately rather than managed solely with cosmetic skincare. The current formula is a cosmetic skincare product intended to improve the visible appearance of the skin; it should not be presented as treating a medical skin condition. Not Suitable For Anyone with a known sensitivity to an ingredient Direct application into or very close to the eyes Significantly irritated or broken skin Those who cannot tolerate fragranced skincare without first checking suitability People using multiple acids, retinoids or prescription skincare should consider their complete routine to minimise unnecessary irritation. How to Use Cleanse and gently dry the skin. Apply 3–4 drops in the morning. Apply over the face, neck and décolleté. Avoid the immediate eye area. Follow with moisturiser if required. Always finish your morning routine with broad-spectrum SPF. The lightweight serum can be worn underneath make-up. La Roche-Posay recommends morning application after cleansing, followed by moisturiser and daily SPF.

What does La Roche-Posay Vitamin C12 Serum do? La Roche-Posay Vitamin C12 Serum is designed to improve visible signs of skin ageing and dullness. Its 12% pure vitamin C formula helps visibly smooth fine lines and wrinkles while improving radiance and the appearance of uneven skin tone. Salicylic acid complements the vitamin C by helping refine skin texture, while Neurosensine provides soothing skincare benefits. It is suitable for all skin types, including sensitive and combination skin. 2. How much vitamin C is in La Roche-Posay Vitamin C12 Serum? The current formulation contains 12% pure vitamin C in the form of ascorbic acid. This is an increase from the previous La Roche-Posay Pure Vitamin C10 formulation. The brand describes pure vitamin C as its key active for improving radiance and visibly smoothing fine lines and wrinkles. The serum's packaging also incorporates UV protection to help protect the active molecule from degradation caused by light. 3. Is La Roche-Posay Vitamin C12 Serum suitable for sensitive skin? Yes. La Roche-Posay states that Vitamin C12 Serum is suitable for all skin types, including sensitive and combination skin. However, 12% pure ascorbic acid is an active formula and the serum also contains salicylic acid, alcohol denat. and fragrance. Those with particularly reactive skin may prefer to introduce it gradually and monitor tolerance rather than immediately combining it with several other active skincare products. 4. When should I use La Roche-Posay Vitamin C12 Serum? La Roche-Posay recommends using the serum in the morning. After cleansing, apply approximately 3–4 drops to the face, neck and décolleté. It can then be followed by your usual moisturiser. Always complete the morning routine with an appropriate broad-spectrum sunscreen. Its lightweight, fast-absorbing texture is designed to sit comfortably underneath moisturiser, SPF and make-up. 5. Does Vitamin C12 Serum help with fine lines and wrinkles? Yes, in cosmetic terms. La Roche-Posay states that the serum is clinically proven to help correct the appearance of fine lines and wrinkles. The formula contains 12% pure vitamin C and is specifically positioned as an anti-ageing and radiance serum. It is designed to improve the visible appearance of ageing skin rather than provide a medicinal treatment. 6. Can La Roche-Posay Vitamin C12 Serum improve dull-looking skin? Radiance is one of the main concerns targeted by the formula. La Roche-Posay reports that 93% of women in a self-assessment involving 63 participants noticed improved radiance after two weeks. The serum is therefore particularly relevant for people whose complexion appears dull or uneven and who want to introduce a concentrated antioxidant product into their daily skincare routine. 7. Does La Roche-Posay Vitamin C12 Serum contain salicylic acid? Yes. The formula contains salicylic acid alongside 12% pure vitamin C. Salicylic acid is a beta-hydroxy acid used in cosmetic skincare for its exfoliating properties and to help refine skin texture. Because it is already present in this serum, people who use separate exfoliating acids should consider their overall routine and reduce overlapping active products if dryness or irritation develops. 8. Does Vitamin C12 Serum contain hyaluronic acid? Yes. The published ingredient list contains both sodium hyaluronate and hydrolysed hyaluronic acid. These are forms of hyaluronic acid commonly incorporated into skincare formulations for their hydrating and skin-conditioning properties. The formula also contains glycerin, another humectant ingredient. 9. Can I use Vitamin C12 Serum with retinol? Vitamin C and retinol can form part of the same overall skincare routine, but sensitive skin may find using several active ingredients together irritating. A simple approach is to use Vitamin C12 Serum in the morning, as recommended by La Roche-Posay, and a retinol product at night. Introduce active products gradually and reduce frequency if you experience persistent redness, burning, peeling or sensitivity. 10. Can I use La Roche-Posay Vitamin C12 Serum every day? Yes, it is designed for regular morning use when tolerated. Apply 3–4 drops after cleansing and follow with moisturiser and SPF. If you are new to pure vitamin C or have very sensitive skin, starting less frequently and gradually increasing use can make it easier to assess tolerance. Avoid introducing several new exfoliating or active skincare products at exactly the same time. 11. Does La Roche-Posay Vitamin C12 Serum contain fragrance or alcohol? Yes. Alcohol denat. and parfum/fragrance are both present in the current published ingredient list. Many users may tolerate the formulation well, and La Roche-Posay positions it as suitable for sensitive skin, but these ingredients can be relevant for individuals with known fragrance sensitivities or particularly reactive skin. Always check the ingredient list on the product received because cosmetic formulations can change. 12. What should I apply after La Roche-Posay Vitamin C12 Serum? After applying 3–4 drops of Vitamin C12 Serum, allow it to settle and follow with an appropriate moisturiser if needed. During the morning, always finish with broad-spectrum sunscreen. Depending on your skin needs, the serum can be paired with a hydrating product such as La Roche-Posay Hyalu B5 and an Anthelios facial sunscreen to create a simple antioxidant, hydration and sun-protection routine. La Roche-Posay specifically recommends daily SPF after Vitamin C12 Serum.
