Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate exfoliation for your acne, blemishes, and breakouts due to the presence of Lipo-Hydroxy Acid (LHA) and Capryloyl Salicylic Acid, which provide mild chemical exfoliation suitable for your combination skin. Prunus Amygdalus Dulcis Milk offers emollient action to complement the exfoliating benefits.
  • The formula is safe for your combination skin, as it lacks prohibited or harsh ingredients that could cause irritation.
  • It provides excellent exfoliating for smoothing skin texture due to high concentrations of Lipo-Hydroxy Acid (LHA) and Lactic Acid.

How to apply

  • You can use this exfoliating toner in your PM routine. Start by using it 1 time per week and increase slowly if your skin is happy.
  • Apply your exfoliating toner right after cleansing and before your moisturizing steps. This helps your skin stay clean and clear.
  • Gently press 2-3 drops of the exfoliating toner into your skin with your hands. Avoid rubbing to keep your face calm.
  • Apply the exfoliating toner on clean and dry skin for the best comfort. Let it dry for a minute ⏱ before moving on.
  • Always do a patch test before your first use and avoid putting the product too close to your eyes.

Kiehl's Daily Refining Milk-Peel Toner is a great fit because it offers moderate exfoliation for breakouts using Lipo-Hydroxy Acid and Lactic Acid. These ingredients help smooth out your skin texture while almond milk keeps it soft and comfortable. The formula is also safe and unlikely to cause irritation on your skin.

Which ingredients make this toner a good fit for acne-prone skin?

This toner is a great fit for acne-prone skin because it contains Lipo-Hydroxy Acid, Lactic Acid, and Salicylic Acid, which offer mild chemical exfoliation to help smooth texture and manage breakouts. These acids work to clear pores and control oil while almond milk and squalane help keep skin soft and comfortable.

Journal of Cosmetic Dermatology, 2021Journal of Cosmetic Dermatology, 2023

What does Capryloyl Salicylic Acid do for acne-prone skin?

Capryloyl salicylic acid helps clear acne and smooth acne-prone skin by gently removing dead skin cells and excess oil. Studies show it works well to reduce both inflamed bumps and closed bumps while keeping the skin calm.

Journal of Cosmetic Dermatology, 2023Journal of Drugs in Dermatology, 2013

What does Lactic Acid do for acne-prone skin?

Where does this toner go in a skincare routine for acne-prone skin?

This exfoliating toner fits into your routine as a cleansing toner used in the evening, starting once a week to see how your skin tolerates it.

Can I use this toner with retinol, and in what order?

You can use this toner with retinol, but it is best to use them on different nights or times of day to keep your skin calm and avoid irritation. Using both exfoliating acids and retinol at the same time may dry out your skin or make it overly sensitive.

How often should I use this toner?

Start by using this exfoliating toner once a week, and if your skin feels good and you see nice results, you can carefully use it more often. The gentle acids help smooth skin texture and manage breakouts without causing harsh irritation.
