Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening and evening of skin tone for your combination skin, as Kojic Acid and Niacinamide work to regulate melanogenesis and reduce hyperpigmentation. Panthenol and Ascorbyl Glucoside provide hydration and antioxidant effects, offering general skincare benefits for your oily shine.
  • The formula is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
  • While beneficial for hydration and antioxidant effects, the product lacks sufficient ingredients to fully address all concerns for combination skin.

How to apply

  • Use your serum as part of your PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
  • Apply the serum after cleansing and toner, and right before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and wait a minute ⏳for it to soak in.
  • Apply the serum on clean and dry skin since your skin is not sensitive.
  • Always do a patch test before using the serum for the first time, and avoid the eye area .

Questions and answers

How well does NINEL ESS B-BOOST treatment work for combination skin?

This treatment works moderately well for combination skin by brightening uneven tone and providing hydration, though other options fit it better. To truly thrive, combination skin needs products rich in niacinamide and ingredients like propolis or zinc PCA that balance oiliness and enhance radiance without causing irritation.

The British Journal of Dermatology, 2002American Journal of Clinical Dermatology, 2002

Which ingredients make this treatment a good fit for combination skin?

Kojic Acid and Niacinamide make this treatment a good fit by helping to even out your skin tone and reduce dark spots, while Panthenol and Ascorbyl Glucoside add moisture and protect against damage. To work best for combination skin, a treatment of this type needs extra ingredients like propolis or zinc PCA to fully balance oiliness and hydration without leaving oily areas overwhelmed.

The British Journal of Dermatology, 2002American Journal of Clinical Dermatology, 2002

What does Kojic Acid do for combination skin?

Kojic Acid helps fade dark spots and uneven patches on combination skin by slowing down the pigment production in your skin cells. It is generally safe to use, though it may occasionally cause mild redness or irritation in sensitive areas.

Biomedicine & Pharmacotherapy = Biomedecine & Pharmacotherapie, 2019The Journal of Pharmacy and Pharmacology, 1994

What does Niacinamide do for combination skin?

Niacinamide helps balance oily areas by reducing excess shine and pore size while keeping dry patches hydrated and smooth. It also works to calm redness and even out skin tone, making it very suitable for combination skin.

Where does this treatment go in a skincare routine for combination skin?

This treatment goes in your evening routine, applied after cleansing and before your moisturizer. Putting treatments in the evening provides extra safety around sun exposure, and this product is unlikely to irritate your skin as it contains no harsh ingredients.

Can I use this treatment with retinol, and in what order?

You can use this treatment with retinol, but apply them on alternating nights to prevent irritation on your combination skin. When using them together in a routine, a product of this type needs extra soothing ingredients and lightweight hydrators to keep oily and dry areas balanced.

How often should I use this treatment?

You can use this treatment in your evening routine, applying it when your skin is clean. A product of this type needs more balancing ingredients and extra hydration to fully address all the needs of combination skin.

Can this treatment clog pores, cause breakouts or purging for combination skin?

This treatment is unlikely to clog pores or cause breakouts for combination skin because its formula is safe and free of harsh ingredients. Combination skin typically needs lightweight hydration and balancing ingredients like niacinamide and panthenol to keep pores clear and skin calm.
