Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your dry and sensitive skin, as glycolic acid and salicylic acid can lead to dryness and irritation, though propanediol provides some humectant action.
- The presence of alcohol denat and glycolic acid can be drying for your dry skin, making the formula moderately unsuitable.
How to apply
- Use your exfoliant PM once a week to help with dryness. Start ⏳3 times a week only if your sensitive skin tolerates it well.
- Apply the exfoliant after cleansing and toning, but always before your favorite moisturizer .
- Gently press 2-3 drops of the exfoliant into your skin and avoid any rubbing. Let it absorb ⏱ for a minute before layering.
- Since your skin is reactive and sensitive, apply the exfoliant on completely dry skin for better tolerance.
- Always do a patch test before your first use and avoid the delicate eye area .

Questions and answers
Why does Lovi advise caution with La Roche-Posay Effaclar Serum for dry sensitive skin?
Lovi advises caution because glycolic acid, salicylic acid, and alcohol denat can easily cause dryness and irritation on dry and sensitive skin. An exfoliant treatment for this skin type needs gentle hydrating ingredients and skin barrier support without harsh drying components.
Which ingredients make this exfoliant a poor fit for dry sensitive skin?
Glycolic acid, salicylic acid, and alcohol denat make this exfoliant a poor fit for your dry sensitive skin because they may cause dryness and irritation. To better suit dry sensitive skin, an exfoliant of this type needs gentle hydrating ingredients, ceramides, and barrier-supporting components that provide moisture without irritation.
International Journal of Cosmetic Science, 2024Journal of Cosmetic Science, 2017
What does Glycolic Acid do for dry sensitive skin?
Glycolic acid can be too harsh for dry sensitive skin and may cause irritation, so this skin type needs gentle calming ingredients and deeply nourishing moisturizers to keep the skin barrier safe and smooth.
Acta Dermato-venereologica, 1995The British Journal of Dermatology, 1997
What does Salicylic Acid do for dry sensitive skin?
Salicylic acid is generally a poor fit for dry, sensitive skin because it is designed to clear out pores by removing excess oil, which can easily leave dry skin irritated. A product of this type needs gentle exfoliating helpers paired with rich, soothing moisturizers and barrier-repairing ingredients to keep dry skin calm and comfortable.
Where does this exfoliant go in a skincare routine for dry sensitive skin?
This exfoliant treatment goes in your evening routine, but use it with caution because it is a poor match for dry sensitive skin. A product of this type needs gentle exfoliating ingredients paired with rich hydrating and soothing ingredients to protect your skin barrier.
Can I use this exfoliant with retinol, and in what order?
Using this exfoliant with retinol on dry and sensitive skin is likely to cause excessive dryness and irritation, so you should avoid using them together. To safely treat this skin type, products need soothing ingredients and gentle hydrators like glycerin and hyaluronic acid without drying alcohols or harsh acids.
How often should I use this exfoliant?
You should use this exfoliant just once a week on your dry sensitive skin, as strong acids like glycolic acid and salicylic acid may cause dryness and irritation. If your skin tolerates it well and stays calm, you can carefully use it more often. A product of this type for dry sensitive skin needs gentle hydrating ingredients and soothing agents to keep the skin comfortable and smooth.
Can this exfoliant clog pores, cause breakouts or purging for dry sensitive skin?
This exfoliant may cause initial breakouts and skin irritation, as reviewers frequently report drying and purging when using it on dry skin. A product of this type needs gentle hydrating ingredients and soothing agents to keep dry skin calm and comfortable.
Is this exfoliant fragrance-free and alcohol-free?
It contains fragrance (parfum) and drying alcohol (alcohol denat).
