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 the presence of ascorbic acid, tocopherol vitamin e, and ferulic acid, which provide antioxidant protection and support collagen synthesis.
- While beneficial for general skincare, the formula does not specifically target oily shine concerns.
- The product is safe for your oily skin, with no risks of irritation from harsh ingredients and the inclusion of soothing tocopherol vitamin e.
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.
People Say
★4.6Overall rating based on 1000+ reviewsBased on a very large amount of data, users widely regard this serum as an effective, affordable alternative to high-end Vitamin C serums, praising its ability to fade hyperpigmentation and brighten the complexion. While the water-light texture is a hit for oily skin, the product's instability requires fridge storage to prevent rapid oxidation, and the potent formula can be irritating for sensitive skin types.

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

Free Radical Biology & Medicine, 2003International Journal of Dermatology, 2017
Where does this serum go in a skincare routine for oily skin?
This treatment goes in the evening routine after cleansing and before moisturizing, though some serums of this type can also be used in the morning or twice a day. It is safe for oily skin and helps brighten the skin tone, but to properly care for oily skin, a product of this type also needs ingredients that target oily shine.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol, but apply them at different times of the day to keep your skin calm and avoid irritation. Use this vitamin c treatment in your morning routine and save your retinol for the evening routine. This serum needs ingredients that specifically target oily shine and help balance excess oil production for this skin type.
How often should I use this serum?
You can use this treatment in the evening as part of your routine, or occasionally in the morning, while starting slowly to see how your skin feels. Antioxidant serums like this help protect against daily damage and brighten your skin tone over time. To better fit oily skin, this product also needs ingredients that specifically target oily shine.
Can this serum clog pores, cause breakouts or purging for oily skin?
This serum is unlikely to clog pores or cause breakouts for your oily skin, as it has a safe formula with no harsh ingredients that typically trigger irritation. However, because it does not target oily shine concerns, an oily skin type needs a product that also helps balance oil and keep pores clear.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
