Lovi Assistant explains
- Offers mild exfoliation and pore-refining effects with azelaic acid and niacinamide, which may be too drying for your dry and sensitive skin due to a lack of sufficient humectant and emollient ingredients.
- While the ingredients offer general skincare benefits, they are not optimally supportive for your dry or flaky skin concerns.
- The product is generally safe for your skin, with a low risk of irritation from azelaic acid.
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.
People Say
★4.8Overall rating based on 500+ reviewsUsers with acne-prone and sensitive skin highly praise this serum for its ability to calm redness and soothe inflammation without causing irritation.

Questions and answers
Why is NINELESS Azelaic Acid Serum a weak match for dry sensitive skin?
This serum is a weak match for dry sensitive skin because its mild exfoliation and pore-refining ingredients may turn out too drying without enough deep moisturizing and softening components to support dry or flaky areas. A treatment of this type needs rich moisturizing and nourishing ingredients that provide deep hydration and skin barrier support without any risk of irritation.
Which ingredients make this serum a poor fit for dry sensitive skin?
Azelaic acid and niacinamide make this serum a poor fit because they provide mild exfoliation and pore-refining effects that may be too drying for your dry and sensitive skin. This serum lacks sufficient hydrating and nourishing ingredients, which a treatment of this type needs to lock in moisture and protect dry or flaky skin.
What does Azelaic Acid do for dry sensitive skin?
Azelaic acid is generally not an ideal fit for dry sensitive skin because it may cause stinging, irritation, or dryness, though it can help calm redness and soothe inflammation when formulated gently. To work well for dry sensitive skin, a product of this type needs calming plant extracts, rich moisturizers, and barrier-repairing ingredients to keep the skin soft and comfortable.
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
Where does this serum go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine once a week to help prevent dryness and irritation. To better fit dry sensitive skin, this type of product needs deeply hydrating ingredients and rich moisturizing softeners.
Can I use this serum with retinol, and in what order?
This serum is a weak match for your dry and sensitive skin because its ingredients may be too drying without enough hydrating and softening ingredients to support flaky skin. A product for this skin needs plenty of gentle hydrating and softening ingredients to keep it comfortable.
How often should I use this serum?
You should use this treatment once a week in the evening, as it may be too drying for your dry and sensitive skin. If your skin tolerates it well and you see good results, you can carefully use it more often. A product of this type needs rich moisturizing and soothing ingredients like plant oils, ceramides, and glycerin to keep dry skin soft and comfortable.
Can this serum clog pores, cause breakouts or purging for dry sensitive skin?
This serum has a low likelihood of causing initial purging on dry sensitive skin. While the formula is generally safe, a product of this type needs rich moisturizing and soothing ingredients to properly comfort dry skin.
