While many with sensitive skin find the formula gentle and effective for brightening, some users express frustration with the product oxidizing too quickly and the dropper design leading to wastage. - Liked: Improves texture (often mentioned) - Liked: Lightweight feel (often mentioned) - Liked: Gentle formula (sometimes noted) - Liked: Pleasant scent (sometimes noted) - Disliked: High price (sometimes noted) - Disliked: Oxidizes quickly (sometimes noted) - Disliked: Poor dropper (sometimes noted) - Disliked: Strong scent (rarely noted) ## How to apply - Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well. - Apply the serum after cleansing and toning, but right before your moisturizer for the best results. - Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product. - Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night. - Avoid the delicate eye area and do a patch test before using the serum for the very first time. - Video: https://storage.pora.ai/c879dda8655a61c19d3d8c9ebad6b06d.mp4 ## Questions and answers ### How well does La Roche-Posay Pure Vitamin C12 Sérum work for oily skin? La Roche-Posay Pure Vitamin C12 Sérum works moderately well for oily skin by offering brightening and smoothing, but it lacks sufficient ingredients to control excess shine. A product for this skin type needs seboregulating ingredients like niacinamide, zinc PCA, and ferulic acid to manage oil and pores, along with barrier-supporting agents like ceramides and panthenol. Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/) ### Which ingredients make this serum a good fit for oily skin? Ascorbic acid and hyaluronic acid make this serum a fit by brightening and smoothing your oily skin while keeping it hydrated. However, to truly manage oily shine and excess oil, a treatment of this type needs ingredients like niacinamide, zinc PCA, and soothing extracts. Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/) ### What does Vitamin C do for oily skin? Vitamin C helps brighten skin tone and smooth texture while providing antioxidant protection that prevents sebum oxidation. For oily skin, this type of product typically needs to be paired with oil-controlling or pore-clearing ingredients like salicylic acid or plant extracts. Sources: [International Journal of Cosmetic Science, 2005](https://pubmed.ncbi.nlm.nih.gov/18492184/) ### What does Glycerin do for oily skin? Glycerin helps keep oily skin hydrated without feeling heavy and supports the skin barrier. Because this product is a weak fit for your skin, an ideal product of this type needs lightweight hydrators and ingredients that balance oil while protecting the skin. Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [International Journal of Toxicology, 2019](https://pubmed.ncbi.nlm.nih.gov/31840548/) ### Where does this serum go in a skincare routine for oily skin? This treatment goes in the evening routine after cleansing and before moisturizing, though some serums can also be used in the morning or twice a day. An oily skin type needs a product of this type to include ingredients that help control oil and shine. ### Can I use this serum with retinol, and in what order? You can use this serum with retinol by applying the vitamin C serum in the morning and your retinol at night. Because this product lacks sufficient oil-controlling ingredients, oily skin types also need dedicated oil-regulating ingredients like salicylic acid or niacinamide to properly manage excess shine. ### How often should I use this serum? You can use this treatment in the evening, as Lovi routines place treatments in the evening for simplicity and extra safety around sun exposure. This serum is safe for your oily skin, with no risks of irritation from harsh ingredients. To better manage oily shine, an oily skin product needs ingredients that help balance oil production. Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/) ### Can this serum clog pores, cause breakouts or purging for oily skin? This serum is unlikely to cause breakouts or clog pores on oily skin because it has a safe formula with no harsh ingredients that typically trigger irritation. However, a product for oily skin really needs extra ingredients to help control shine and balance oil throughout the day. ### Is this serum fragrance-free and alcohol-free? It has no fragrance and contains drying alcohol (alcohol denat). ## Alternatives for oily skin - [Clinique Fresh Pressed Daily Booster with Pure Vitamin C 10%](https://lovi.care/skincare/ae/p/clinique/fresh-pressed-daily-booster-with-pure-vitamin-c-10/for/oily-skin) — Superior fit — AED 365.22 at Amazon - [SkinCeuticals C E Ferulic](https://lovi.care/skincare/ae/p/skinceuticals/c-e-ferulic/for/oily-skin) — High fit — AED 715.99 at Amazon - [NEOGEN DERMALOGY REAL VITA C SERUM](https://lovi.care/skincare/ae/p/neogen-dermalogy/real-vita-c-serum/for/oily-skin) — High fit — AED 89.30 at Amazon ## Pairs well with - Cleanser: [CeraVe Foaming Facial Cleanser](https://lovi.care/skincare/ae/p/cerave/foaming-facial-cleanser/for/oily-skin) — Superior fit — AED 49.95 at Amazon - Hydrating Toner: [SOME BY MI Snail Truecica Miracle Repair Toner](https://lovi.care/skincare/ae/p/some-by-mi/snail-truecica-miracle-repair-toner/for/oily-skin) — Superior fit — AED 49.99 at Amazon - Moisturizer: [COSRX Oil-Free Ultra-Moisturizing Lotion with Birch Sap](https://lovi.care/skincare/ae/p/cosrx/oil-free-ultra-moisturizing-lotion-with-birch-sap/for/oily-skin) — Superior fit — AED 33.40 at Amazon ## Where to buy - Amazon.ae: AED 143.65 (https://www.amazon.ae/dp/B07PM79MSC?tag=lovi00-21&linkCode=osi&th=1&psc=1) Prices checked 6 Nov 2026. ## Ingredients Water, Ascorbic Acid, Glycerin, Alcohol Denat, Propylene Glycol, Pentylene Glycol, Polysorbate 20, Sodium Hydroxide, Hyaluronic Acid, Adenosine, Caprylyl Glycol, Hydrolyzed Hyaluronic Acid, Xanthan Gum, Tocopherol, Phenoxyethanol ## About the Lovi Fit Lovi: Unbiased, science-based skincare AI trained on real user outcomes.
