Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers excellent brightening and evening of skin tone for your oily skin, as 3-O-Ethyl Ascorbic Acid and Salicylic Acid work to exfoliate and improve skin tone, effectively reducing oily shine.
- The moderate concentrations of these key ingredients promote cell turnover and reduce sebum production, making it highly suitable for your oily skin type.
- The safety profile is excellent, 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.
People Say

Questions and answers
What makes Kiehl's Clearly Corrective Dark Spot Solution a great fit for oily skin?
This treatment is a great fit because 3-O-Ethyl Ascorbic Acid and Salicylic Acid gently exfoliate your oily skin, improve skin tone, and help reduce oily shine. The moderate amounts of these key ingredients encourage cell turnover and lower oil production, and it has a very safe profile that is unlikely to cause irritation.
Which ingredients make this serum a good fit for oily skin?
3-O-Ethyl Ascorbic Acid and Salicylic Acid make this serum a great fit for your oily skin because they help exfoliate, improve your skin tone, and reduce oily shine. The moderate amounts of these key ingredients also help promote cell turnover and lower oil production.
What does Activated C do for oily skin?
Activated charcoal products lack clinical evidence to support claims that they can treat oily skin conditions like acne. Oily skin instead needs ingredients that help balance sebum production and gently clear pores.
What does Birch Extract do for oily skin?
Birch extract is unlikely to help oily skin directly since it lacks oil-controlling benefits. Oily skin needs lightweight ingredients like herbal extracts and balancing agents to reduce shine and keep pores clear.
Where does it go in a skincare routine for oily skin?
This treatment goes in your evening routine, as treatments with active ingredients are typically used at night for simplicity and extra safety around sun exposure. It is unlikely to irritate your skin and helps brighten tone while reducing oily shine.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol, but it is best to apply them on alternate nights or use one in the morning and the other at night to prevent irritation. This helps your oily skin benefit from both brightening and cell-renewing ingredients safely.
How often should I use it?
Apply this treatment in your evening routine once a week to start, and if your skin feels comfortable and looks good, you may carefully use it more often. It helps brighten your skin tone and reduce oily shine safely without causing irritation.
Can this serum clog pores, cause breakouts or purging for oily skin?
This serum is unlikely to clog pores or cause breakouts on oily skin, as its ingredients help clear dead skin and control oily shine without harshness. It has an excellent safety profile, meaning it works gently while you treat dark spots.
Is it fragrance-free and alcohol-free?
It contains fragrance (linalool) and drying alcohol (alcohol denat).
