Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your dry or flaky skin due to the presence of salicylic acid and capryloyl salicylic acid, which provide mild chemical exfoliation.
- Niacinamide and glycerin offer some hydration, but the keratolytic action of the exfoliants may exacerbate dryness for your dry skin.
How to apply
- Apply this serum PM, starting 3×/week and working up to daily use as your skin adjusts.
- Place the serum after cleansing and toner, but right before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on slightly damp skin to help lock in extra moisture.
- Avoid the eye area and do a patch test before your first use.

Questions and answers
Why does Lovi advise caution with La Roche-Posay Effaclar Duo (+) for dry skin?
Lovi advises caution because the exfoliants in this treatment may make dry skin even drier, although it does contain ingredients like niacinamide and glycerin that offer some hydration. Treatments that fit dry skin well need to focus on deep hydration, barrier support, and soothing ingredients like ceramides, peptides, or propolis to nourish the skin without causing irritation.
Which ingredients make this cream a poor fit for dry skin?
Salicylic acid and capryloyl salicylic acid make this cream a poor fit because their peeling action may worsen your dryness. Treatments for dry skin need rich hydrators, soothing ingredients like propolis, ceramides, or peptides, and skin barrier support to nourish and keep it soft.
What does Niacinamide do for dry skin?
Niacinamide helps dry skin by strengthening the skin barrier, increasing hydration, and reducing water loss. It supports ceramide production and helps keep the surface smooth and calm. This ingredient tends to be very well tolerated and is unlikely to irritate dry skin.

What does Zinc PCA do for dry skin?
Where does this cream go in a skincare routine for dry skin?
This treatment goes in the evening routine after cleansing and before your moisturizer, used just once a week to start. Because your skin is dry, the exfoliating ingredients may make dryness worse, so this type of product needs rich hydrators like glycerin and soothing ingredients like niacinamide to keep skin comfortable.
Can I use this cream with retinol, and in what order?
Using this exfoliating cream with retinol is not recommended for dry skin, because the combination of exfoliants and drying ingredients may severely worsen flaking and irritation. Dry skin needs a gentle routine focused on barrier repair, heavy moisturizers, and soothing hydrators rather than multiple strong active ingredients.
How often should I use this cream?
This treatment is a poor fit for dry skin, but if you choose to use it, start by applying it just once a week in the evening. A product of this type needs soothing and deeply moisturizing ingredients like ceramides, hyaluronic acid, and glycerin to keep dry skin comfortable.
Can this cream clog pores, cause breakouts or purging for dry skin?
This cream may cause dryness or peeling on dry skin, as its exfoliating ingredients can make flaking worse. A product for this skin needs rich hydrating ingredients and gentle barrier-protecting components to keep it soft and smooth without causing irritation.
Is this cream fragrance-free and alcohol-free?
It has no drying alcohol and contains fragrance (parfum).
What the research says
