Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Highly suitable for your normal skin due to the presence of glycerin and sodium hyaluronate for humectant action and panthenol for barrier repair.
- Offers moderate moisturizing due to the presence of glycerin and panthenol in concentrations that hydrate and enhance barrier resilience, though these benefits are mostly supportive for your main goal of addressing pigmentation.
- The safety profile is excellent, with no risks of irritation for your normal skin due to the absence of prohibited or harsh ingredients.
How to apply
- Could be used as part of your AM and PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
- Apply this moisturizer after your cleanser and toner, right before your morning SPF.
- Gently press a small amount of the moisturizer into your skin. Avoid rubbing it too hard so it absorbs nicely.
- For the best moisture, you can apply it when your skin is slightly damp. This helps your skin stay soft and happy.
- Remember to avoid the eye area when applying. Always do a patch test before your first use.

Questions and answers
What makes La Roche-Posay Hyalu B5 Serum a great fit for skin with dark spots?
La Roche-Posay Hyalu B5 Serum is a great fit for skin with dark spots because it is very safe and unlikely to cause irritation. It helps keep your skin hydrated and supports the skin barrier with glycerin, sodium hyaluronate, and panthenol, which are helpful additions alongside your main dark spot routine.
Clinical, Cosmetic and Investigational Dermatology, 2017The Journal of Dermatological Treatment, 2017
Which ingredients make this serum a good fit for skin with dark spots?
Glycerin and sodium hyaluronate make this serum a good fit by keeping your skin hydrated, while panthenol helps repair the skin barrier. These supportive ingredients work well together to maintain healthy skin while you address dark spots.
Clinical, Cosmetic and Investigational Dermatology, 2017The Journal of Dermatological Treatment, 2017
What does Hyaluronic Acid do for skin with dark spots?
Hyaluronic acid is unlikely to directly fade dark spots, but it helps keep dry and uneven skin plump and deeply hydrated. To effectively target dark spots, this type of skin needs brightening ingredients like vitamin C or niacinamide alongside your hydrator.
What does Panthenol do for skin with dark spots?
Panthenol helps soothe and moisturize the skin, improving overall hydration and keeping the barrier strong while you treat dark spots. It is unlikely to directly fade dark spots on its own, so skin with dark spots typically needs targeted brightening ingredients like niacinamide.
The Journal of Dermatological Treatment, 2017American Journal of Clinical Dermatology, 2002
Where does this serum go in a skincare routine for skin with dark spots?
This serum goes in the evening routine after cleansing and before moisturizing, which keeps things simple and protects your skin while you sleep. It is very gentle and unlikely to cause irritation on normal skin, helping support hydration while you work on dark spots.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first to keep your skin hydrated and supported while it adjusts to the retinoid. This combination is unlikely to cause irritation because the product has a very safe formula with soothing ingredients that help maintain your skin barrier.
