Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and evening of skin tone for your oily skin due to Kojic Acid and Tranexamic Acid, which help regulate melanin production.
- While Panthenol and Niacinamide provide hydration and soothing benefits, they offer limited direct support for your primary acne and breakout concerns.
- The product is safe for your oily skin, with no risk of irritation from harsh ingredients and the inclusion of soothing components.
How to apply
- Could be used as part of your PM routine. Start 3 times a week and build up to daily use if your skin tolerates it well.
- Apply your serum after cleansing and toning, but before putting on your moisturizer.
- Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on clean, dry skin to help manage your blemishes safely.
- Do a patch test before your first use and avoid the delicate eye area.

Questions and answers
How well does NINEL ESS B-BOOST treatment work for oily acne-prone skin?
NINEL ESS B-BOOST works moderately well for oily acne-prone skin, offering some brightening and calming benefits while having limited direct impact on breakouts. A treatment of this type needs dedicated breakout-fighting ingredients like benzoyl peroxide or oil-controlling antioxidants to best suit oily and acne-prone skin.
Which ingredients make this treatment a good fit for oily acne-prone skin?
Niacinamide and Panthenol make this treatment a fit by providing hydration and soothing benefits for your oily skin. Treatments that fit this skin best need effective ingredients like benzoyl peroxide, niacinamide, or propolis to target breakouts, control excess oil, and improve texture without irritation.
What does Kojic Acid do for oily acne-prone skin?
Kojic acid helps fade dark spots and calm oily acne-prone skin because it has antioxidant and anti-inflammatory properties. It is generally safe to use, though this skin type also needs ingredients that clear pores and control oil.
What does Niacinamide do for oily acne-prone skin?
Niacinamide helps balance oil production, calms redness, and is unlikely to irritate oily, acne-prone skin while improving blemishes. Clinical tests show it reduces excess oil and helps clear up both inflammatory and non-inflammatory acne breakouts.
Journal of Cosmetic and Laser Therapy, 2006Journal of Cosmetic Dermatology, 2024
Where does this treatment go in a skincare routine for oily acne-prone skin?
This treatment goes in the evening routine, placed after cleansing and toning and before moisturizing. While it is safe and provides gentle hydration and brightening for oily skin, an acne-prone skin type needs targeted ingredients like salicylic acid or benzoyl peroxide to directly address breakouts.
Can I use this treatment with retinol, and in what order?
You can use this treatment alongside retinol by applying the treatment first in your evening routine and following it with your moisturizer. While this product is safe for your oily skin and unlikely to cause irritation, oily acne-prone skin often needs ingredients that directly target breakouts and blemishes.
How often should I use this treatment?
You can use this treatment in your evening routine, applying it once a week at first and carefully building up if your skin tolerates it well. It is safe for your oily skin and unlikely to cause irritation.
Can this treatment clog pores, cause breakouts or purging for oily acne-prone skin?
This treatment is unlikely to clog pores or cause breakouts for your oily skin, as it has a safe formula with a negligible risk of irritation. However, because it offers limited direct support for breakouts, oily acne-prone skin needs a product with ingredients that specifically target blemishes and clear pores.
What the research says
Topical 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 topical gel containing chitosan, chlorhexidine, allantoin, and dexpanthenol significantly reduced postoperative pain, trismus, swelling, and analgesic consumption, while improving wound healing after third molar surgery compared to a placebo.
Medicina Oral, Patologia Oral Y Cirugia Bucal, 2020A 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 oily acne-prone skin better
Adapalene 0.1%-benzoyl peroxide 2.5% fixed-dose combination gel provided significantly greater, synergistic efficacy and a faster onset of action compared with the vehicle, adapalene monotherapy, and benzoyl peroxide monotherapy in patients with acne vulgaris.
The British Journal of Dermatology, 2009Topical benzoyl peroxide 5% gel treatment improved acne severity, sebum, stratum corneum hydration, and transepidermal water loss, while significantly reducing microbial diversity and the prevalence of Cutibacterium in 33 patients with acne vulgaris.
Dermatologic Therapy, 2022A cream combining propolis, tea tree oil, and Aloe vera reduced erythema scars, acne severity index, and total lesion count better than erythromycin cream in sixty patients with mild to moderate acne vulgaris compared to placebo.
