Questions and answers
How well does NINEL ESS B-BOOST work for mature skin?
NINEL ESS B-BOOST works moderately well for mature skin by helping to brighten your skin tone and offering supportive hydration that leaves your skin feeling calm and smooth. While it is very safe and well-tolerated, this skin type needs a treatment that exceptionally targets wrinkles and fine lines with high concentrations of potent antioxidants, nourishing oils, and peptides.
Which ingredients make this treatment a good fit for mature skin?
Kojic Acid and Niacinamide help brighten and even out your skin tone, while Panthenol and Ascorbyl Glucoside provide supportive hydration for fine lines. Because this treatment is only an average fit for mature skin, a product of this type needs high concentrations of potent antioxidants, hydrating components, and skin-repairing ingredients that effectively target wrinkles and fine lines.
What does Kojic Acid do for mature skin?
Kojic acid helps fade dark spots and uneven patches on mature skin by blocking the enzyme responsible for dark pigment. It also provides antioxidant protection, though this skin type also needs nourishing hydrators and gentle exfoliants to keep the surface smooth and soft.
Biomedicine & Pharmacotherapy = Biomedecine & Pharmacotherapie, 2019
What does Niacinamide do for mature skin?
Niacinamide helps mature skin by smoothing out fine lines and wrinkles, reducing dark spots, and improving overall skin elasticity. It is also very well tolerated and supports a strong skin barrier to keep skin looking healthy.
Where does it go in a skincare routine for mature skin?
This treatment goes in the evening routine before your moisturizer. Mature skin needs products with antioxidants, gentle brighteners, and hydrating ingredients to improve tone and smooth fine lines.
Can I use this treatment with retinol, and in what order?
This treatment is unlikely to irritate your skin, but because it is an average fit for mature skin, a product of this type needs extra wrinkle-smoothing and firming ingredients like peptides and retinoids to truly care for your skin. When combining them, apply your retinol first, let it absorb, and then follow with this treatment.
How often should I use it?
You can use this treatment in the evening as part of your routine for mature skin. A product of this type needs antioxidant ingredients like kojic acid and niacinamide to help brighten skin tone, along with hydrating ingredients like panthenol to keep dry skin smooth.
Can this treatment clog pores, cause breakouts or purging for mature skin?
This treatment is unlikely to clog pores or cause breakouts for mature skin. It has a very safe formula without harsh ingredients, though this skin type also needs rich hydrators and firming peptides to stay smooth and soft.
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, 2002Topical treatment of nicotinamide, alone or in combination with other active ingredients, reduces the progression of skin aging and hyperpigmentation in clinical trials while being well tolerated.
Antioxidants, 2021A 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.
