Lovi Assistant explains
- Offers moderate brightening for your oily skin due to ascorbic acid, which aids in evening skin tone and provides antioxidant activity, complemented by glycerin for humectant action.
- Hyaluronic acid and tocopherol offer general hydration and supportive benefits for your oily skin and acne concerns, though specialized ingredients for directly targeting acne are absent.
- The formulation is safe for your oily skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Could be used as part of your PM routine. Start 3 times a week and build up to daily use if your skin tolerates it well.
- Apply your serum after cleansing and toning, but before putting on your moisturizer.
- Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on clean, dry skin to help manage your blemishes safely.
- Do a patch test before your first use and avoid the delicate eye area.

Questions and answers
How well does La Roche-Posay Pure Vitamin C12 work for oily acne-prone skin?
This serum offers moderate brightening and hydration for your oily skin with vitamin C and glycerin, though it lacks specialized ingredients for directly targeting acne. A treatment of this type needs effective ingredients like niacinamide and propolis that provide excellent skincare benefits for acne, excess oil, and uneven texture without any risk of irritation.
Which ingredients make this serum a good fit for oily acne-prone skin?
Ascorbic acid helps brighten your oily skin and even out its tone, while glycerin and hyaluronic acid provide light hydration without heaviness. To be a better fit for this skin type, a treatment of this type needs specialized acne-fighting ingredients like niacinamide or propolis alongside soothing extracts for daily comfort and oil control.
What does Vitamin C do for oily acne-prone skin?
Vitamin C helps brighten skin, smooth out texture, and improve uneven spots for oily acne-prone skin. It may also help fade marks left behind by blemishes.
What does Glycerin do for oily acne-prone skin?
Glycerin helps keep oily acne-prone skin hydrated without feeling heavy. It draws moisture into the skin while supporting the skin barrier so it stays soft and balanced.
The British Journal of Dermatology, 2008Clinical, Cosmetic and Investigational Dermatology, 2017
Where does this serum go in a skincare routine for oily acne-prone skin?
This treatment serum goes in the evening routine after cleansing and before moisturizing, which keeps the application simple and safe around sun exposure. To properly care for oily acne-prone skin, this type of product also needs specialized ingredients that directly target breakouts and blemishes.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol, but it is best to apply them at different times of day or alternate nights to avoid irritation. Since this contains vitamin C, use it in your morning routine and save your retinol for the evening routine. This helps your skin stay bright and smooth while lowering the chances of redness or discomfort.
How often should I use this serum?
You can use this treatment serum in your evening routine, as suggested for simplicity and extra safety around sun exposure. This product works for your oily skin, though an oily acne-prone skin needs a product with specialized ingredients to directly target acne.
Can this serum clog pores, cause breakouts or purging for oily acne-prone skin?
This serum is unlikely to clog pores or cause breakouts for your oily skin because it has a safe formula without harsh ingredients, but a product of this type needs specialized acne-fighting ingredients to directly target breakouts.
Is this serum fragrance-free and alcohol-free?
It has no fragrance and contains drying alcohol (alcohol denat).
