Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and evening of skin tone due to the presence of Kojic Acid and Niacinamide, which help regulate melanogenesis but provide minimal emollient action for your dry skin.
- While Panthenol and Ascorbyl Glucoside offer some hydration and antioxidant benefits, they do not sufficiently address the dryness and flakiness characteristic of your skin.
- The formulation is safe for your dry and sensitive skin, as it lacks prohibited or harsh ingredients that could cause irritation.
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 is NINEL ESS B-BOOST a weak match for dry sensitive skin?
NINEL ESS B-BOOST is a weak match because it offers brightening ingredients like kojic acid and niacinamide that help regulate skin tone, but it provides minimal hydration to address your dry and flaky skin. A treatment of this type needs rich moisturizing and nourishing ingredients that provide excellent hydration, support the skin barrier, and protect against dryness without causing irritation.
Which ingredients make this treatment a poor fit for dry sensitive skin?
Kojic acid, niacinamide, and tranexamic acid make this treatment a weak match because they do not provide enough softness and moisture to help your dry skin. A treatment for dry sensitive skin needs rich moisturizing components and barrier-supporting ingredients to keep it comfortable and smooth.
What does Kojic Acid do for dry sensitive skin?
Kojic acid may not be the best fit for dry sensitive skin because it can sometimes cause stinging and contact irritation. A product for this skin type needs gentle brightening ingredients and soothing, moisturizing benefits to keep the skin calm and soft.
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 it go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine after your toner and before your moisturizer. It is a weak match for your dry skin because it lacks the rich, soothing hydrators needed to keep dry skin soft and comfortable.
Can I use this treatment with retinol, and in what order?
This treatment is safe to use with retinol, but because it is a weak match for dry sensitive skin, it needs extra soothing and rich moisturizing ingredients to prevent dryness and flakiness. Apply it after your soothing toner and before your moisturizer in your evening routine.
How often should I use it?
This treatment should be used once a week in the evening for your dry sensitive skin, and if you tolerate it well and see good results, you can carefully use it more often. A product of this type needs rich softening ingredients and extra hydration to properly care for dry skin and prevent flakiness.
Can this treatment clog pores, cause breakouts or purging for dry sensitive skin?
This treatment is unlikely to clog pores, cause breakouts or trigger purging on dry sensitive skin, as its formula lacks heavy or irritating ingredients. A product of this type needs rich, soothing moisturizers and nourishing oils to effectively comfort and soften dry, flaky skin.
What the research says
Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer.
The British Journal of Dermatology, 2002Topical dexpanthenol acts as a moisturizer, improves stratum corneum hydration, accelerates wound healing and epidermal regeneration, reduces erythema, and improves symptoms of skin irritation compared to vehicle or no pretreatment.
American Journal of Clinical Dermatology, 2002A new topical panthenol-containing emollient significantly improved transepidermal water loss reduction, stratum corneum hydration, and intercellular lipid lamellae length compared with control in healthy subjects without negatively impacting bacterial viability.
The Journal of Dermatological Treatment, 2017A topical formulation containing kojic acid, emblica extract, and glycolic acid demonstrated efficacy parity compared with hydroquinone 4% in multiethnic participants with mild to moderate facial dyschromia.
Cutis, 2010A nanoemulsion containing 1 mg/mL kojic dipalmitate and 5% rosehip oil demonstrated high incorporation efficiency, suitable physicochemical stability, antioxidant and depigmenting efficacy close to 1 mM ascorbic acid, and no cytotoxicity at concentrations from 0.06% to 1% in vitro.
Pharmaceutics, 2023Topical application of iron chelators kojic acid and deferiprone significantly accelerated wound healing in rats compared to control groups, with deferiprone showing superior efficacy due to higher antioxidant and iron chelation abilities.
International Wound Journal, 2013Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin.
Journal of Cosmetic Dermatology, 2021Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women.
The Journal of Investigative Dermatology, 2008Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging.

Why other serums fit dry sensitive skin better
A formulation containing glycerol (5%) and xylitol (5%) applied twice daily for 14 days increased skin hydration, filaggrin protein quantity, interdigitation index, and biomechanical properties, and decreased transepidermal water loss compared to untreated and vehicle-treated skin in twelve volunteers with dry skin.
Acta Dermato-venereologica, 2017Glycerol accelerates barrier repair and improves stratum corneum hydration compared to untreated and base-treated sites.
Acta Dermato-venereologica, 1999In 50 participants with sensitive skin, a Ceramide NP C15-containing emollient improved skin barrier function with a significant reduction in transepidermal water loss and induced modest changes in skin microbiota compared to the vehicle.
