Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and evening of skin tone for your normal skin due to the presence of tetrahexyldecyl ascorbate and glutathione, which provide antioxidant benefits and improve skin tone.
- While it offers general skincare benefits like hydration and antioxidant protection, it lacks specialized anti-inflammatory ingredients to address your redness and irritation concerns.
- The product is safe for your normal skin with sensitivity, as it contains no prohibited or harsh ingredients that could cause irritation.
How to apply
- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
- Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
- Always do a patch test before your first use and avoid getting the serum too close to your eyes .

Questions and answers
How well does Paula's Choice 25% Vitamin C + Glutathione Clinical Serum work for sensitive skin?
This product works for sensitive skin, though other treatments fit it better. While it is unlikely to cause irritation, it lacks specialized ingredients to calm redness and soothe irritation. Treatments that fit this skin best need effective calming ingredients and skin-repairing components that address redness without any risk of irritation.
Which ingredients make this serum a good fit for sensitive skin?
This serum works for sensitive skin because it contains gentle antioxidants like Ascorbic Acid, Glutathione, Ergothioneine, Ascorbyl Glucoside, and Tocopherol that help brighten and protect your skin safely. However, because it lacks specialized anti-inflammatory ingredients for redness and irritation, a product for this skin needs soothing and calming ingredients like niacinamide and snail secretion filtrate to fully address those concerns.
What does Vitamin C do for sensitive skin?
Vitamin C helps brighten skin, smooth out fine lines, and fade dark spots. Clinical studies show it is generally safe and well-tolerated when improving overall skin quality.
Journal of Cosmetic Dermatology, 2020Journal of Cosmetic Dermatology, 2023
What does Glutathione do for sensitive skin?
Glutathione helps calm sensitive skin by reducing oxidative stress and protecting against environmental irritation. It is unlikely to cause irritation and has a very safe profile when used on the skin.
Journal of the European Academy of Dermatology and Venereology, 2024Indian Journal of Dermatology, Venereology and Leprology, 2016
Where does this serum go in a skincare routine for sensitive skin?
This treatment goes in the evening routine after your soothing toner and before your moisturizer. A product of this type needs soothing and calming ingredients to help keep sensitive skin comfortable while brightening the tone.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying your retinol product at night and using this vitamin C treatment in the morning or on alternate nights to avoid overwhelming your sensitive skin. This product is safe for sensitive skin, but to address redness and irritation concerns, a product of this type needs specialized calming and anti-inflammatory ingredients.
How often should I use this serum?
This serum works well in your evening routine, and a product of this type needs soothing ingredients to help calm redness and irritation on sensitive skin.
Can this serum clog pores, cause breakouts or purging for sensitive skin?
This serum is unlikely to cause breakouts or clog pores for sensitive skin, as it has a very low complaint rate for causing breakouts. To care for sensitive skin properly, a product of this type needs soothing, anti-inflammatory ingredients to calm redness and irritation.
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.
