Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and evening of skin tone for your oily skin, as tetrahexyldecyl ascorbate and glutathione provide antioxidant and brightening effects that are generally beneficial but not directly targeted at your acne, blemishes, and breakouts.
- The presence of ascorbyl glucoside and Pyrus Malus Fruit Extract offers some antioxidant and potential seboregulating benefits, which are supportive for oily skin.
- The product 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 Paula's Choice 25% Vitamin C + Glutathione Clinical Serum work for oily acne-prone skin?
This serum offers moderate brightening for your oily skin, though it is not directly targeted at your acne and breakouts. An acne-prone skin type needs ingredients like niacinamide and propolis to balance oil and target breakouts without irritation.
Which ingredients make this serum a good fit for oily acne-prone skin?
Tetrahexyldecyl ascorbate, glutathione, and ascorbyl glucoside make this serum a fit by providing antioxidant and brightening effects, while apple fruit extract offers supportive oil-balancing benefits. For this skin type, a treatment needs ingredients like niacinamide and propolis to directly target acne and blemishes while controlling excess oil.
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.
Journal of Cosmetic Dermatology, 2020Journal of Cosmetic Dermatology, 2023
What does Glutathione do for oily acne-prone skin?
Glutathione helps protect oily, acne-prone skin from daily stress and irritation by acting as an antioxidant that supports a healthy skin barrier. It is unlikely to clog pores, but this skin type also needs ingredients that clear out oil and soothe redness to stay calm and smooth.
Journal of the European Academy of Dermatology and Venereology, 2024Current Problems in Dermatology, 2001
Where does this serum go in a skincare routine for oily acne-prone skin?
Apply this serum in your evening routine, using it after cleansing and toning and before applying your moisturizer. To best care for oily acne-prone skin, a product of this type needs additional ingredients that directly target breakouts and blemishes alongside brightening benefits.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the retinol first and following with this treatment, or by using one in the morning and the other at night. Because this product does not contain harsh ingredients, it is unlikely to irritate your skin, though an oily acne-prone skin often needs treatments that directly target breakouts and blemishes with ingredients like salicylic acid or benzoyl peroxide.
How often should I use this serum?
This treatment is used in the evening, applying it once a day for simplicity and extra safety around sun exposure. It is safe for your skin with no risks of irritation due to the absence of harsh ingredients. Oily acne-prone skin needs this type of product to include antioxidants and brightening ingredients that help even skin tone, along with oil-balancing ingredients.
Facial Plastic Surgery, 2014Clinical, Cosmetic and Investigational Dermatology, 2014
Can this serum clog pores, cause breakouts or purging for oily acne-prone skin?
This serum is unlikely to cause breakouts or clog pores on oily acne-prone skin because it lacks harsh ingredients, though a few reviewers have reported occasional blemishes. An average fit for your skin like this one needs targeted blemish-fighting ingredients and oil-balancing agents to properly clear breakouts while brightening.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol. Cetyl alcohol is a fatty alcohol, which soften the skin.
