Lovi Assistant explains
- Offers excellent exfoliation for your normal skin due to glycolic acid and salicylic acid, which effectively decongest pores and smooth texture without causing irritation.
- While beneficial for general skin health, the formula's exfoliating properties are not specifically targeted to address your primary concerns of redness and irritation.
- The product is safe for your normal skin with sensitivity, as it lacks harsh ingredients and poses no risk of irritation.
How to apply
- Use your exfoliant PM once a week to help with redness and irritation. Start slowly and only increase frequency if your skin feels happy and comfortable.
- Apply the exfoliant after cleansing and toner , but always before your moisturizer . This ensures the product absorbs properly into the skin.
- Gently press 2-3 drops of the exfoliant into your skin without rubbing . Let it absorb for a minute before moving on.
- Since your skin is sensitive , apply the exfoliant on completely dry skin for the best tolerance. This helps prevent any extra stinging or discomfort.
- Always do a patch test before your first use and avoid the delicate eye area .

Journal of Cosmetic Dermatology, 2024Clinical, Cosmetic and Investigational Dermatology, 2019
Which ingredients make this serum a good fit for sensitive skin?
This serum is a great fit for your sensitive skin because it contains glycolic acid, salicylic acid, and capryloyl salicylic acid, which effectively smooth texture and decongest pores. It also includes niacinamide and biosaccharide gum-1 to help keep your skin calm and comfortable.
Journal of Cosmetic Dermatology, 2024Clinical, Cosmetic and Investigational Dermatology, 2019
What does Glycolic Acid do for sensitive skin?
Glycolic acid can be too harsh for sensitive skin, leaving it dry and irritated, so this type of skin needs a gentler exfoliating ingredient and calming plant extracts to keep the skin barrier safe and comfortable.
What does Salicylic Acid do for sensitive skin?
Salicylic acid may cause irritation on sensitive skin, so it requires careful use and good sun protection to keep skin comfortable. A product for this skin type needs gentle, soothing ingredients and a mild formula that respects the skin barrier.
The British Journal of Dermatology, 1999International Journal of Toxicology, 2003
Where does this serum go in a skincare routine for sensitive skin?
This serum goes in your evening routine, applied after your cleanser and soothing toner and before your moisturizer. Lovi routines start exfoliating steps once a week, and people who tolerate them well and see good results may carefully use them more often.
Can I use this serum with retinol, and in what order?
This serum can be used alongside retinol by applying it during your evening routine after cleansing and toning, and before moisturizing. Because both ingredients are strong, using them together may cause dryness, so it is best to introduce them slowly or alternate nights to keep your skin calm and comfortable.
How often should I use this serum?
Start using this serum once a week in your evening routine, and if your sensitive skin tolerates it well and shows good results, you can carefully use it more often. This approach helps you build tolerance safely while smoothing your skin texture and decongesting pores.
Can this serum clog pores, cause breakouts or purging for sensitive skin?
This serum may cause initial breakouts or purging when you first start using it due to the exfoliating ingredients that clear out deep congestion. However, it is unlikely to cause lasting irritation on sensitive skin since it is formulated without harsh irritants.
Journal of Cosmetic Dermatology, 2024Clinical, Cosmetic and Investigational Dermatology, 2019
Is this serum fragrance-free and alcohol-free?
It contains fragrance (parfum) and drying alcohol (alcohol denat).
What the research says
