Lovi Assistant explains

  • Highly suitable for your oily skin, this serum contains niacinamide for seboregulation and rhododendron ferrugineum extract for antioxidant activity, while malassezin and niacinamide work to reduce blemishes and even skin tone.
  • Glycerin and sodium hyaluronate provide hydration, supporting overall skin health without directly targeting your primary concerns of acne, blemishes, and breakouts.
  • The formula is safe for your oily skin, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing bisabolol.

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 the Molecular Hero Serum work for oily acne-prone skin?

This serum works reasonably well for oily acne-prone skin, as it contains niacinamide and malassezin to help reduce blemishes and even out skin tone. While it provides gentle hydration without causing irritation, treatments that rate higher for this skin type tend to feature a targeted combination of oil-controlling ingredients, antioxidants like vitamin C, and soothing plant extracts.

The British Journal of Dermatology, 2002Clinical, Cosmetic and Investigational Dermatology, 2017

Which ingredients make this serum a good fit for oily acne-prone skin?

Niacinamide and malassezin make this serum a good fit for oily acne-prone skin by helping control oil, reduce blemishes, and even out skin tone. To work best for this skin type, a treatment of this kind also needs targeted ingredients for oil control and blemishes, such as vitamin C or propolis, along with soothing extracts.

The British Journal of Dermatology, 2002

What does Malassezin do for oily acne-prone skin?

Malassezin is not a strong fit for oily, acne-prone skin because this skin type requires ingredients that balance oil production and soothe inflammation without feeding yeast overgrowth.

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 serum go in a skincare routine for oily acne-prone skin?

This serum goes in the evening routine after cleansing and before moisturizing. Oily acne-prone skin needs a treatment with ingredients like niacinamide and salicylic acid to help control oil and target breakouts.

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

Yes, you can use this treatment with retinol by applying the treatment first and then following with your retinol. Because this serum has a safe profile with soothing ingredients like bisabolol, it is unlikely to irritate your skin when paired with retinoids.

Journal of Cosmetic Dermatology, 2024

How often should I use this serum?

Apply this serum in your evening routine for simplicity and extra safety around sun exposure. People who tolerate it well and see good results can carefully use it more often.

Can this serum clog pores, cause breakouts or purging for oily acne-prone skin?

This serum is unlikely to cause clogged pores, breakouts, or irritation on oily acne-prone skin because it avoids harsh ingredients and includes soothing bisabolol. However, because it focuses on hydration rather than directly targeting acne, oily acne-prone skin generally needs a product with ingredients specifically focused on clearing blemishes and keeping pores clear.

Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
