Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening for your normal skin due to Ascorbic Acid and Ascorbyl Glucoside, which provide antioxidant benefits and support collagen production.
- While the formula offers general hydration and cleansing, these benefits are mostly supportive and not directly targeted at your redness and irritation.
- The product is safe for your sensitive skin as it lacks harsh or prohibited ingredients, minimizing irritation risks.
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 Obagi Professional-C Serum 20% work for sensitive skin?
Obagi Professional-C Serum 20% works moderately well for sensitive skin, as it is safe and provides brightening and hydration, though it does not directly target redness and irritation. A treatment for sensitive skin needs ingredients like niacinamide or soothing plant extracts that directly calm redness and irritation while keeping the skin soft and comfortable.
Which ingredients make this serum a good fit for sensitive skin?
Ascorbic Acid and Ascorbyl Glucoside make this serum a fit by offering antioxidant benefits that support brightening, while Sodium Hyaluronate provides hydration. Though it is safe and minimizes irritation risks, it lacks ingredients that directly target redness. Sensitive skin of this type needs products with ingredients like niacinamide and snail secretion filtrate to properly calm redness and irritation.
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.
What does Hyaluronic Acid do for sensitive skin?
Hyaluronic acid helps calm and hydrate sensitive skin while supporting the skin barrier to keep it soft and comfortable. Clinical studies show it improves surface moisture and reduces dryness, roughness, and redness without irritation.

Where does this serum go in a skincare routine for sensitive skin?
This serum goes in the evening routine after cleansing and a soothing toner, followed by a moisturizer. A product for sensitive skin of this type needs calming ingredients and extra hydration to directly target redness and irritation.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum in your morning routine and the retinol in your evening routine to help prevent irritation on sensitive skin. Using them at different times of day allows you to get the brightening benefits of vitamin C without overwhelming your skin with too many strong treatments at once.
How often should I use this serum?
This treatment is used in the evening for simplicity and extra safety around sun exposure, though some treatments can also be used in the morning or twice a day. This product works for your sensitive skin, but since it does not target redness and irritation, sensitive skin needs a product that brings soothing and calming ingredients to keep skin calm and comfortable.
Can this serum clog pores, cause breakouts or purging for sensitive skin?
This serum is unlikely to cause breakouts or clog pores on sensitive skin because it lacks heavy, pore-clogging ingredients. However, it may occasionally cause mild dryness or irritation since it does not directly target redness.
Is this serum fragrance-free and alcohol-free?
It has no fragrance and contains drying alcohol (alcohol).
