Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for dry or flaky skin due to the presence of glycolic acid and salicylic acid, which provide chemical exfoliation but can be drying and irritating for your dry skin.
- The formulation is unsuitable for your dry skin due to alcohol denat and glycolic acid, which can be drying and irritating, rather than providing the emollient and humectant actions needed.
How to apply
- Use this exfoliant as part of your PM routine once a week, increasing slowly to twice a week if your dry skin tolerates it well. Always remember to apply SPF every morning to protect your newly smoothed skin.
- Apply the exfoliant after cleansing and toning, but always before your rich moisturizer.
- Gently press 2-3 drops of the exfoliant into your skin and let it absorb for a minute. Avoid rubbing to prevent any irritation on flaky areas.
- Apply the product directly to dry clean skin to ensure the best possible tolerance for your dry type. This helps address flaky patches without causing extra stress.
- Avoid the sensitive eye area and do a quick patch test before your very first use. Do not mix this with other strong acids or retinoids on the same night.

Questions and answers
Why does Lovi advise caution with La Roche-Posay Effaclar Ultra Concentrated Serum for dry skin?
This serum is a poor match for dry skin because ingredients like glycolic acid and alcohol denat can be drying and irritating rather than providing the moisture and softening care dry skin needs. A product for this skin needs nourishing, soothing ingredients that add deep moisture and support the skin barrier with components like ceramides, vitamin C, peptides, or propolis.
Which ingredients make this serum a poor fit for dry skin?
Alcohol denat and glycolic acid make this serum a poor fit because they can be drying and irritating for your dry skin, rather than providing the moisture and softening actions needed. Dry skin needs formulations rich in soothing ingredients that provide significant hydration, ceramides, and skin barrier support without any risk of irritation.
What does Glycolic Acid do for dry skin?
Glycolic acid helps smooth and soften dry skin by speeding up the shedding of older surface cells. Because it can also cause the skin to lose more moisture, dry skin needs extra hydrating ingredients like glycerin or hyaluronic acid alongside it to keep the skin comfortable.
What does Salicylic Acid do for dry skin?
Salicylic acid is generally not a good fit for dry skin, as it is meant to clear out pores and remove dead skin rather than hydrate. Because dry skin needs soothing and moisture rather than exfoliation, a product for dry skin needs nourishing ingredients like urea to lock in moisture and keep the skin soft.
Where does this serum go in a skincare routine for dry skin?
This exfoliant treatment goes in the evening routine after cleansing and before moisturizing, though it may be too drying for dry skin. Dry skin needs products containing ingredients that add and lock in moisture to keep the skin soft and smooth.
Can I use it with retinol, and in what order?
Using this product with retinol is not recommended because both ingredients can be very drying and irritating for your dry skin. This skin type needs gentle, hydrating ingredients and moisturizing creams instead of strong chemical exfoliants.
How often should I use this serum?
This exfoliant treatment is a poor match for your dry skin, as its ingredients may be drying and irritating. To use a product of this type safely on dry skin, start just once a week and look for formulas that provide soothing and moisturizing benefits instead.
Can it clog pores, cause breakouts or purging for dry skin?
This exfoliant treatment may cause initial breakouts and drying for dry skin because its acids and alcohol denat can irritate rather than provide the rich moisture and hydration needed.
Is this serum fragrance-free and alcohol-free?
It contains fragrance (parfum) and drying alcohol (alcohol denat).
