Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and evening of skin tone for your oily skin, as ascorbic acid and ferulic acid provide antioxidant protection and support collagen synthesis. While these ingredients can offer some oil control benefits, the serum lacks specialized ingredients to directly address your primary concern of oily shine.
- The formulation includes panthenol and sodium hyaluronate, which provide hydration and soothing effects beneficial for overall skin health.
- The product is safe for your oily skin, with no risks of irritation due to the absence of prohibited or 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 Timeless 20% Vitamin C + E Ferulic Acid Serum work for oily skin?
This serum works moderately well for oily skin by providing antioxidant protection and brightening, but it lacks specialized ingredients to directly control oily shine. A treatment for this skin needs ingredients like niacinamide and zinc PCA to manage excess oil and enlarged pores while keeping the skin comfortable and balanced.
Journal of Cosmetic Dermatology, 2020American Journal of Clinical Dermatology, 2002
Which ingredients make this serum a good fit for oily skin?
Ascorbic acid and ferulic acid help brighten your oily skin and provide antioxidant protection. To be a better fit for oily skin, a product of this type needs ingredients like niacinamide and zinc PCA to control excess oil and manage shine.
What does Vitamin C do for oily skin?
Vitamin C helps brighten skin tone and smooth texture while providing antioxidant protection that prevents sebum oxidation. For oily skin, this type of product typically needs to be paired with oil-controlling or pore-clearing ingredients like salicylic acid or plant extracts.
International Journal of Cosmetic Science, 2005Journal of Cosmetic Dermatology, 2023
What does Vitamin E do for oily skin?
Vitamin E helps balance oily skin by reducing excess oil and calming redness. It is also unlikely to clog pores while helping to keep your skin smooth and properly hydrated.
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. Because this serum lacks specialized ingredients for oily shine, an oily skin type needs a product that includes targeted oil control ingredients to help manage excess oil.
Can I use this serum with retinol, and in what order?
Yes, you can use this serum with retinol by applying the vitamin C in the morning and retinol at night, or waiting a few minutes between them if used in the same routine. This helps reduce the likelihood of skin irritation while still giving you brightening and smoothing benefits.
How often should I use this serum?
You can use this treatment in your evening routine once a week to start, and if your oily skin tolerates it well and sees good results, you can carefully use it more often. It is unlikely to irritate your skin, but because it is an average fit for oily shine, this skin type needs targeted ingredients that actively control excess oil.
Can this serum clog pores, cause breakouts or purging for oily skin?
This serum is unlikely to cause clogged pores, breakouts, or purging for oily skin. Its safe formulation and soothing ingredients help keep your skin calm, though an oily skin type needs a product with specialized oil-control ingredients to properly manage shine.
American Journal of Clinical Dermatology, 2002The Journal of Dermatological Treatment, 2017
Is this serum fragrance-free and alcohol-free?
It has no drying alcohol and contains fragrance (benzyl alcohol).
