Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your dry and sensitive skin as salicylic acid and capryloyl salicylic acid provide mild chemical exfoliation, though glycerin is included for humectant action.
- Niacinamide and zinc PCA aid in reducing blemishes and smoothing texture, offering moderate treatment for acne-prone 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
Why does Lovi advise caution with La Roche-Posay Effaclar Duo for dry sensitive skin?
Lovi advises caution because this treatment contains exfoliating acids that may dry out or irritate sensitive skin, even though it includes glycerin for moisture. A product for this skin needs rich hydrating and nourishing ingredients, gentle moisture retention, and skin barrier support without any risk of irritation.
Which ingredients make this treatment a poor fit for dry sensitive skin?
Salicylic acid and capryloyl salicylic acid make this treatment a poor fit because they exfoliate skin that is already dry and sensitive, which may lead to irritation. A product of this type needs rich moisturizing and nourishing ingredients that provide deep hydration and support the skin barrier without any risk of irritation.
What does Niacinamide do for dry sensitive skin?
Niacinamide helps dry sensitive skin by calming irritation and keeping moisture locked in so your face feels soft and smooth. It works to build up your skin barrier and calm redness while being very gentle and unlikely to cause irritation.
Journal of Cosmetic Dermatology, 2004International Journal of Pharmaceutics, 2013
What does Zinc PCA do for dry sensitive skin?
Zinc PCA is unlikely to provide the deep moisture and rich comfort that dry sensitive skin needs. A product for this skin type needs soothing ingredients and gentle hydrators to keep the face soft and calm without irritation.
Where does this treatment go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine once a week to start, as acids and other exfoliating steps need careful introduction on dry sensitive skin. A product of this type needs gentle chemical exfoliants paired with deeply hydrating ingredients and barrier-repairing lipids to keep dry and delicate skin feeling soft and calm.
Can I use this treatment with retinol, and in what order?
You should use caution when combining this treatment with retinol, as both can easily dry out and irritate your skin. If you do use them together, apply the retinol first, let it absorb, and then follow with this treatment, or better yet, alternate nights to keep your skin calm and comfortable.
How often should I use this treatment?
This product is a poor match for your dry and sensitive skin, so you should use it cautiously just once a week to test your skin's tolerance. If you want to care for this skin type, a product of this type needs soothing and hydrating ingredients like glycerin and ceramides to keep it calm and smooth.
Can this treatment clog pores, cause breakouts or purging for dry sensitive skin?
This treatment may cause dryness, peeling, or new breakouts on dry sensitive skin because of the strong exfoliating acids it contains. This skin type needs gentle, hydrating ingredients like ceramides and hyaluronic acid to keep it soft and calm without irritation.
