Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate benefits for your oily skin, as niacinamide and rhododendron ferrugineum extract provide antioxidant protection and help regulate oil production, though they do not directly address oily shine.
- Sodium hyaluronate and bisabolol offer general hydration and soothing effects, which are supportive but not primary for your main concern.
- The product is safe for your oily skin, with no risks of irritation due to the absence of harsh ingredients.
How to apply
- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.

Questions and answers
How well does Molecular Hero Serum work for oily skin?
Mother Science Molecular Hero Serum works reasonably well for oily skin by offering moderate benefits like antioxidant protection and oil regulation, though it does not directly target oily shine. To better manage oily skin, a treatment of this type needs ingredients like niacinamide, zinc PCA, and ferulic acid that control excess oil and pores while maintaining a healthy glow.
Which ingredients make this serum a good fit for oily skin?
Niacinamide and rhododendron ferrugineum extract make this serum a fit for your oily skin by providing antioxidant protection and helping regulate oil production, while sodium hyaluronate and bisabolol offer general hydration and soothing effects. To fit oily skin even better, a treatment of this type needs ingredients that control sebum production and manage oily shine, such as ferulic acid and zinc PCA, along with barrier-supporting ceramides.
What does Malassezin do for oily skin?
Malassezin is unlikely to directly treat oily skin, but it helps brighten skin and fade dark patches with a safety profile comparable to standard treatments. For oily skin specifically, a product of this type needs lightweight hydrators and oil-balancing ingredients to manage shine while improving tone.
What does Niacinamide do for oily skin?
Niacinamide helps balance oily skin by significantly reducing excess oil production and shine. It is well tolerated and may improve skin texture without clogging pores.
Journal of Cosmetic and Laser Therapy, 2006Antioxidants, 2021
Where does this serum go in a skincare routine for oily skin?
This treatment serum goes in the evening routine after cleansing and before moisturizing, though some can also be used in the morning or twice a day. It is safe for oily skin and is unlikely to cause irritation.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the treatment in your evening routine after cleansing and toning, followed by your moisturizer. This product is safe for your skin with no risks of irritation due to the absence of harsh ingredients.
How often should I use this serum?
You can use this treatment in the evening as part of your routine. It is unlikely to irritate your oily skin, but a product for this skin needs ingredients that directly balance oil production and reduce shine.
Can this serum clog pores, cause breakouts or purging for oily skin?
This serum is safe for your oily skin and is unlikely to cause irritation or breakouts. However, oily skin needs targeted ingredients like salicylic acid or retinoids to properly clear pores and control excess shine.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
