Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and smoothing for your dry and sensitive skin, as ascorbic acid and hyaluronic acid hydrate and improve skin tone, but alcohol denat may worsen dryness.
- The presence of glycerin and hyaluronic acid provides humectant benefits, though limited emollient ingredients may not offer sufficient barrier support for dry skin.
How to apply
- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

Questions and answers
Why does Lovi advise caution with La Roche-Posay Pure Vitamin C12 for dry sensitive skin?
Lovi advises caution because alcohol in the formula may worsen dryness, and it lacks enough softening ingredients to properly support your skin barrier. A treatment for dry sensitive skin needs soothing, nourishing ingredients that provide deep moisture and protect against irritation.
Clinical, Cosmetic and Investigational Dermatology, 2017Journal of Cosmetic Dermatology, 2020
Which ingredients make this serum a poor fit for dry sensitive skin?
Alcohol denat makes this serum a poor match for dry sensitive skin because it may worsen dryness. A treatment for this skin needs rich moisturizing and nourishing ingredients that provide hydration and skin barrier support without irritation.
What does Vitamin C do for dry sensitive skin?
Vitamin C helps brighten and smooth dry sensitive skin while reducing wrinkles and improving elasticity. It is generally well tolerated and unlikely to cause irritation when properly formulated, leaving the skin looking more radiant.
What does Glycerin do for dry sensitive skin?
Glycerin helps dry sensitive skin by drawing moisture into the skin and keeping it there, making the skin soft and smooth. It is very gentle and unlikely to cause irritation while improving how well the skin holds onto water. This type of skin needs ingredients that boost hydration and repair the barrier without causing stinging.
Clinical, Cosmetic and Investigational Dermatology, 2017The British Journal of Dermatology, 2008
Where does this serum go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine for dry sensitive skin, after cleansing and toning and before moisturizing, though alcohol denat may worsen dryness. A product of this type needs soothing and hydrating ingredients like glycerin and hyaluronic acid along with rich barrier support to keep dry skin comfortable.
Can I use this serum with retinol, and in what order?
It is best to avoid using this serum with retinol on dry sensitive skin, as the alcohol denat may worsen dryness and cause irritation. When using active treatments like this, a product for this skin type needs rich moisturizing ingredients and protective barriers to lock in moisture and prevent discomfort.
How often should I use this serum?
This serum is a poor fit for dry sensitive skin because alcohol denat may worsen dryness, so use caution. If you decide to use it, apply it in the evening once a week to start, and a product of this type needs rich moisturizing ingredients and barrier support for dry skin.
Can this serum clog pores, cause breakouts or purging for dry sensitive skin?
This serum is unlikely to clog pores or cause breakouts on dry sensitive skin, but it may worsen dryness due to its alcohol content. A product of this type needs rich moisturizing ingredients and oils to protect dry skin and prevent further irritation.
Is this serum fragrance-free and alcohol-free?
It has no fragrance and contains drying alcohol (alcohol denat).
What the research says
A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers.
Journal of Cosmetic Dermatology, 2020Topical hyaluronic acid filler serum combined with Botulinum toxin type A lengthened the duration of the toxin's effect in reducing wrinkles compared to Botulinum toxin type A alone.
Dermatologic Therapy, 2022Vitamin C mesotherapy produced a significant and earlier reduction in gingival pigmentation and higher patient satisfaction compared to topical gel in twenty healthy non-smokers with hyperpigmented gingiva, with both methods reducing the mean area fraction of melanin-forming cells at 6 months without causing pain.
Clinical Oral Investigations, 2021A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.
Clinical, Cosmetic and Investigational Dermatology, 2017Topical application of 5% vitamin C cream significantly improved global clinical scores, increased skin microrelief density, and induced elastic tissue repair in photoaged skin compared to excipient control in healthy female volunteers.
Experimental Dermatology, 2003Ascorbic acid 2-glucoside gel significantly reduced gingival melanin pigmentation after 4 weeks compared to placebo in 73 subjects with symmetric pigmentation.

Journal of Drugs in Dermatology, 2011Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.
Clinical Oral Investigations, 2022Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days.
