Lovi Assistant explains
- Offers moderate brightening and smoothing for your combination skin due to Ascorbic Acid and Hyaluronic Acid, which provide antioxidant activity and hydration respectively.
- While beneficial for general skin health, the formula's ingredients are not specifically targeted to address your concerns with acne, blemishes, and breakouts.
- The product is safe for your combination skin, as it contains soothing Tocopherol and lacks harsh or prohibited ingredients.
How to apply
- Use your serum as part of your PM routine and start 3x/week before working up to daily use.
- Apply this treatment after cleansing and toner, and before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- Apply the product on clean, dry skin to help manage your breakouts safely.
- Avoid the eye area and do a patch test before your first use.

Questions and answers
How well does La Roche-Posay Pure Vitamin C12 work for acne-prone skin?
La Roche-Posay Pure Vitamin C12 Sérum is an average fit for acne-prone skin because while it provides general brightening and hydration, it does not specifically target breakouts and blemishes. Treatments that work better for this skin type need ingredients like niacinamide, zinc, and propolis to manage oil and soothe blemishes without causing irritation.
Which ingredients make this serum a good fit for acne-prone skin?
Ascorbic acid and hyaluronic acid help brighten and smooth your acne-prone skin, though this treatment is not specifically targeted to address breakouts. To truly fit acne-prone skin well, a product of this type needs ingredients like niacinamide, zinc PCA, or propolis to target blemishes while balancing oil.
What does Vitamin C do for acne-prone skin?
Vitamin C helps brighten skin, smooth out uneven tones, and fade dark spots left behind by breakouts. It is also packed with antioxidants that may help protect acne-prone skin from everyday environmental stress.
What does Glycerin do for acne-prone skin?
Glycerin helps keep acne-prone skin hydrated and calm without clogging pores or feeling heavy. It supports the skin barrier so it stays soft and smooth while handling everyday treatments.

Where does this serum go in a skincare routine for acne-prone skin?
This serum goes in the evening routine after cleansing and before moisturizing. While it is safe for your skin, acne-prone skin needs products that specifically target blemishes and breakouts with ingredients like salicylic acid or niacinamide.
Can I use this serum with retinol, and in what order?
You can use this treatment alongside a retinol, applying the retinol in your evening routine and using this vitamin C serum at a different time of day to avoid irritation. This product works for your skin, though acne-prone skin needs formulas specifically targeted to clear breakouts and blemishes.
How often should I use this serum?
You can use this treatment in the evening as part of your routine. Products of this type for acne-prone skin need targeted ingredients that clear breakouts and soothe irritation.
Can this serum clog pores, cause breakouts or purging for acne-prone skin?
This serum is unlikely to cause purging since it does not contain exfoliating acids, but it may not address your breakouts because it lacks ingredients that target acne. Acne-prone skin needs a product that helps clear pores and calm blemishes, such as salicylic acid or niacinamide.
Is this serum fragrance-free and alcohol-free?
It has no fragrance and contains drying alcohol (alcohol denat).
What the research says
A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers.
Journal of Cosmetic Dermatology, 2020Topical application of 5% vitamin C cream significantly improved global clinical scores, increased skin microrelief density, and induced elastic tissue repair in photoaged skin compared to excipient control in healthy female volunteers.
Experimental Dermatology, 2003Ascorbic acid 2-glucoside gel significantly reduced gingival melanin pigmentation after 4 weeks compared to placebo in 73 subjects with symmetric pigmentation.
Journal of Periodontology, 2009Topical application of VC-IP cream twice daily for 8 weeks reduces periorbital wrinkles in female subjects compared to a placebo cream.
Journal of Cosmetic Dermatology, 2022A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.
Clinical, Cosmetic and Investigational Dermatology, 2017The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol.
Journal of Cosmetic Dermatology, 2020Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant.
International Journal of Cosmetic Science, 2001Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control.
Journal of Drugs in Dermatology, 2011Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.

Why other serums fit acne-prone skin better
Topical nicotinamide plus an antibacterial adhesive agent and zinc-pyrrolidone carboxylic acid combined with adapalene significantly reduced noninflammatory acne lesions by the second week of therapy compared to placebo with adapalene in patients with moderate acne vulgaris.
The Journal of Clinical and Aesthetic Dermatology, 2020A cream combining propolis, tea tree oil, and Aloe vera reduced erythema scars, acne severity index, and total lesion count better than erythromycin cream in sixty patients with mild to moderate acne vulgaris compared to placebo.
Clinical Pharmacology, 2018Niacinamide and ferulic acid incorporated in a stable multiple emulsion successfully reduced melanin, sebum, and skin erythema while improving skin elasticity and hydration in human skin compared to a placebo.
