Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and smoothing benefits for your dry and sensitive skin, as ascorbic acid and ferulic acid provide antioxidant and collagen-boosting effects, while glycerin and sodium hyaluronate offer essential hydration. Panthenol and bisabolol further support barrier repair and soothe irritation, making it generally compatible with your skin type and concerns.
- The formulation is safe for your dry and sensitive skin, with no harsh ingredients and the inclusion of soothing agents like bisabolol and panthenol to minimize potential irritation.
- While the product provides good hydration and antioxidant benefits, its primary brightening and smoothing functions are not the most critical needs for your dry or flaky skin.
How to apply
- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

Questions and answers
How well does Paula's Choice C15 Super Booster work for dry sensitive skin?
Paula's Choice C15 Super Booster works reasonably well for dry sensitive skin by offering moderate brightening along with soothing ingredients like panthenol and bisabolol to help calm irritation. While it provides useful antioxidants and hydration, it is not the most critical match for dry or flaky skin, which generally needs products specifically designed with rich, maximum moisturizing and barrier-supporting ingredients that deliver deep hydration and reliable moisture retention without any risk of irritation.
Clinical, Cosmetic and Investigational Dermatology, 2017The Journal of Dermatological Treatment, 2017
Which ingredients make this serum a good fit for dry sensitive skin?
Glycerin and sodium hyaluronate bring essential moisture, while panthenol and bisabolol help soothe irritation and support barrier repair for dry sensitive skin. A product of this type needs rich moisturizing ingredients and ceramides that provide deep hydration and protect the skin barrier.
Clinical, Cosmetic and Investigational Dermatology, 2017The Journal of Dermatological Treatment, 2017
What does Vitamin C do for dry sensitive skin?
Vitamin C helps brighten and smooth dry sensitive skin while reducing wrinkles and improving elasticity. It is generally well tolerated and unlikely to cause irritation when properly formulated, leaving the skin looking more radiant.
What does Ferulic Acid do for dry sensitive skin?
Ferulic acid helps calm dry sensitive skin by reducing irritation and offering strong antioxidant protection against daily environmental damage. This type of skin needs gentle soothing ingredients and barrier-supporting hydrators to stay soft and calm.
Journal of Cosmetic Dermatology, 2008Journal of Cosmetic Dermatology, 2025
Where does this serum go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine for dry sensitive skin, placed after your cleanser and soothing toner and before your moisturizer. Using antioxidant serums in the evening helps keep things simple and provides extra safety around sun exposure.
Can I use this serum with retinol, and in what order?
This treatment is applied in the evening after your cleanser and toner, and before your moisturizer. It is generally safe for your dry and sensitive skin because it contains soothing ingredients like bisabolol and panthenol that help minimize potential irritation, though using it in the same routine as retinol may increase the likelihood of dryness.
Journal of Cosmetic Dermatology, 2024The Journal of Dermatological Treatment, 2017
How often should I use this serum?
Apply this treatment in the evening as part of your routine. Because your dry and sensitive skin needs intense moisture and barrier repair above all, a product of this type needs rich hydrators like hyaluronic acid and glycerin alongside soothing agents like panthenol and bisabolol to keep your skin calm and comfortable.
Clinical, Cosmetic and Investigational Dermatology, 2017The Journal of Dermatological Treatment, 2017
Can this serum clog pores, cause breakouts or purging for dry sensitive skin?
This serum is unlikely to clog pores or cause breakouts for dry sensitive skin, as its ingredients are generally lightweight and well-tolerated. However, it is not specifically tailored to address the deeper flakiness and intense moisture needs of this skin type.
Clinical, Cosmetic and Investigational Dermatology, 2017The Journal of Dermatological Treatment, 2017
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
