Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate hydration for your dry or flaky skin due to the presence of glycerin and hyaluronic acid, which provide general skincare benefits.
- The inclusion of alcohol denat may be drying for your dry skin, and the formula lacks sufficient emollient ingredients for adequate hydration.
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 Pure Vitamin C12 for dry skin?
La Roche-Posay Pure Vitamin C12 Serum may be drying for your dry skin because it contains alcohol denat and lacks sufficient softening ingredients for adequate hydration. A treatment for dry skin needs rich, soothing ingredients and protective barriers that lock in moisture and nourish the skin without any risk of irritation.
Which ingredients make this serum a poor fit for dry skin?
This serum contains alcohol denat, which may dry out dry skin, and lacks enough rich, softening ingredients to keep it comfortable. A treatment for dry skin needs plenty of heavy, softening ingredients and soothing hydrators like ceramides, niacinamide, or peptides to deeply nourish and protect the skin barrier.
What does Vitamin C do for dry skin?
Vitamin C helps dry skin by boosting moisture and keeping the surface smooth and soft. It may also improve skin hydration and support the outer protective barrier over time.
Skin Research and Technology, 2008Experimental Dermatology, 2008
What does Glycerin do for dry skin?
Glycerin helps dry skin by drawing in moisture and keeping it locked in, which makes the skin feel much softer and smoother. It also supports your natural skin barrier to stop water from escaping easily. A product for dry skin needs extra ingredients like hyaluronic acid and soothing plant extracts to truly calm and hydrate dry patches.
Clinical, Cosmetic and Investigational Dermatology, 2017The British Journal of Dermatology, 2008
Where does this serum go in a skincare routine for dry skin?
This treatment goes in the evening routine after your cleanser and before your moisturizer to keep things simple and safe around sun exposure. A product of this type for dry skin needs rich, softening ingredients and plenty of hydrating ingredients to properly smooth and comfort the skin.
Can I use this serum with retinol, and in what order?
You should use caution when combining this serum with retinol on dry skin, as the alcohol denat in the formula may be drying. Apply this serum in the morning or on alternating nights from your retinol, always following with a rich moisturizer containing heavy oils and butters to prevent further dryness.
How often should I use this serum?
This serum may be drying for your dry skin, so use it carefully once a week to see how your skin tolerates it. A product of this type needs rich, moisturizing ingredients and softening oils to deeply hydrate dry skin.
Can this serum clog pores, cause breakouts or purging for dry skin?
This serum is unlikely to clog pores or cause breakouts on dry skin, though the alcohol in it may leave your skin feeling dry. A treatment for dry skin needs rich, softening ingredients and heavy moisturizers to lock in hydration and smooth flaky patches.
Is this serum fragrance-free and alcohol-free?
It has no fragrance and contains drying alcohol (alcohol denat).
