- The blend of botanical extracts like arnica montana and myrtus communis provides additional soothing benefits, which is beneficial for your goal of addressing redness and irritation.
- The formula is safe for your sensitive skin, containing no harsh ingredients that would cause irritation.
How to apply

- Apply this exfoliating toner after cleansing and before your moisturizer. It fits right into your usual step for toners.
- Gently press 2-3 drops of the exfoliating toner into your skin. Avoid rubbing to keep redness down.
- Apply the exfoliating toner on completely dry skin to help improve your skin's tolerance. This helps protect your sensitive face.

People Say
★4.7Overall rating based on 800+ reviewsThis acid toner is highly praised for dramatically resurfacing skin texture, clearing acne, and creating a radiant glow.

Questions and answers
How well does Biologique Recherche Lotion P50 work for sensitive skin?
Biologique Recherche Lotion P50 works moderately well for sensitive skin, though other products fit it better. Sensitive skin needs a product that offers no risk of irritation, provides calming and hydrating ingredients to soothe redness, and performs its exfoliating function effectively without disrupting the skin's balance.
Which ingredients make this toner a good fit for sensitive skin?
Niacinamide supports your skin barrier, while botanical extracts like arnica montana and myrtus communis provide soothing benefits that help address redness and irritation. To fit sensitive skin even better, a toner of this type needs extra calming and hydrating ingredients that smooth texture and clear blemishes without causing irritation or imbalance.
What does Lactic Acid do for sensitive skin?
Lactic acid may cause stinging and irritation on sensitive skin because sensitive skin often has a fragile barrier and enhanced facial blood flow. To care for sensitive skin, a product of this type needs soothing ingredients like ceramides to strengthen the skin barrier and calm discomfort.
Archives of Dermatological Research, 2018Clinical, Cosmetic and Investigational Dermatology, 2021
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 it go in a skincare routine for sensitive skin?
This exfoliating toner fits into your routine once a week to help smooth texture and reduce blemishes, while other products with calming botanical extracts and soothing hydrators fit sensitive skin better.
Can I use this toner with retinol, and in what order?
You can use this toner with retinol, but it may cause dryness or irritation if used at the same time, so apply it in your morning routine and your retinol at night. Sensitive skin needs gentle exfoliating toners that include soothing botanical extracts and barrier-supporting ingredients to smooth texture while keeping skin calm.
How often should I use it?
Start by using this exfoliating toner once a week, and if your sensitive skin tolerates it well and shows good results, you may carefully use it more often. To better fit sensitive skin, an exfoliating product of this type needs gentle acids combined with soothing botanical extracts and barrier-supporting ingredients like niacinamide to keep skin calm and smooth.
Can this toner clog pores, cause breakouts or purging for sensitive skin?
This toner is unlikely to clog pores or cause breakouts for your sensitive skin because its acids help keep pores clear and smooth texture. However, since it exfoliates, you may experience mild tingling or temporary purging as dead skin cells shed. Sensitive skin of this type needs formulas with gentle soothing ingredients like niacinamide and botanical extracts to keep redness and irritation at bay.
