Works for dry skin; other sunscreens fit it better.
This fit is calculated for the concerns frequently associated with dry skin: flakiness, tightness, dehydration, fine lines, and wrinkles. For scores and recommendations based on your full skin profile, including your 12D face scan results and any goals or preferences you have, please use the Lovi app.
Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate suitability for your dry skin due to the presence of glycerin for humectant action, though it lacks sufficient emollients to fully address dryness.
- The formulation provides excellent UV protection with titanium dioxide and zinc oxide, but its general skincare benefits are mostly supportive and irrelevant for your dry or flaky skin.
How to apply
- Apply this sunscreen during your AM routine every morning. Reapply every two hours when exposed to the sun.
- Apply the sunscreen as the final step in your morning routine after your moisturizer.
- Gently smooth a nickel-sized amount over your face and neck, avoiding harsh rubbing.
- Apply the sunscreen on clean, dry skin to ensure even protection and absorption.
- Avoid the immediate eye area and do a patch test before first use.
People Say

Questions and answers
How well does Algenist Sublime Defense Ultra Lightweight UV Defense Fluid work for dry skin?
This fluid works reasonably well for your dry skin because it includes glycerin to help hold in moisture, though it lacks enough rich softening ingredients to fully care for very dry or flaky areas. A sunscreen for dry skin needs extra rich softening ingredients and heavy moisturizers to deeply soften dry patches and keep the skin smooth all day.
Which ingredients make this fluid a good fit for dry skin?
This fluid has glycerin for holding moisture in your skin, though a product of this type needs richer softening ingredients to fully soothe dry skin.
What does Octinoxate do for dry skin?
Octinoxate is a sunscreen ingredient that protects dry skin from UV rays, though it does not provide moisture itself. Since dry skin needs extra care, a product with this ingredient works best when it also includes rich hydrators like shea butter to keep your skin soft and smooth.
International Journal of Nanomedicine, 2013Journal of Cosmetic Dermatology, 2020
What does Titanium Dioxide do for dry skin?
Titanium dioxide sits on top of dry skin to block UV rays without sinking in or clogging pores. A product of this type needs rich, moisturizing ingredients like shea butter to keep dry skin soft and comfortable.
International Journal of Cosmetic Science, 2000Skin Pharmacology and Applied Skin Physiology, 2001
Where does this fluid go in a skincare routine for dry skin?
This fluid goes at the end of your morning routine after applying a moisturizer. Sun protection products of this type need rich softening ingredients and heavy moisturizing agents to properly care for dry skin.
Can I use this fluid with retinol, and in what order?
You can use this fluid in the morning as the last step after applying your retinol and moisturizer. Because dry skin needs extra moisture and rich smoothing ingredients, this fluid works best when layered over a nourishing cream to prevent tightness.
How often should I use this fluid?
You can use this sunscreen fluid every morning as the final step of your daytime routine. To properly care for dry skin, this type of product needs rich softening ingredients that lock in moisture and deeply soothe flaky areas.
Can this fluid clog pores, cause breakouts or purging for dry skin?
This fluid is unlikely to clog pores or cause breakouts on dry skin, though some users may experience a mild drying sensation. To work better for dry skin, this type of product needs extra rich emollients to deeply lock in moisture and comfort flaky areas.
Is this fluid fragrance-free and alcohol-free?
It contains fragrance (parfum, hexyl cinnamal, and linalool) and drying alcohol (alcohol denat).
What the research says
A 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, 2017Replacing 20% of the chemical UV filter octyl methoxycinnamate with urucum oil in solid lipid nanoparticles maintained the skin protection factor without inducing toxic responses or significant skin penetration in human volunteers.
Skin Pharmacology and Physiology, 2018Liposomal encapsulation of octyl methoxycinnamate increases its safety, skin affinity, and in vivo solar photoprotection factor while slowing its release and enhancing retention in the stratum corneum compared to a conventional formulation.
International Journal of Nanomedicine, 2013Encapsulation of ethylhexyl methoxycinnamate and butyl methoxydibenzoylmethane in lipid microparticles significantly reduced their in vivo human skin penetration compared to nonencapsulated filters.
Skin Pharmacology and Physiology, 2011Microfine titanium dioxide does not penetrate human skin when formulated in an oil-in-water emulsion with the pigment dispersed in the aqueous phase, compared to oily dispersions and liposomal encapsulation which allow deeper skin penetration.
International Journal of Cosmetic Science, 2000Replacing microsized titanium dioxide and zinc oxide with nanoparticles in sunscreens eliminates opaqueness and alters UV protection balance while inducing (photo)cyto- and genotoxicity and penetrating viable skin layers during long-term exposures.
Nanotechnology, Science and Applications, 2011Microfine zinc oxide and titanium dioxide do not penetrate the stratum corneum of porcine skin in vitro, indicating that their use in sunscreens does not pose a health risk from internal exposure.
Toxicology in Vitro, 2006Topical 0.5% hyaluronic-ZnO nanogel applied twice daily reduced inflammatory-lesion counts by 58% at week four in human subjects compared to baseline without causing erythema.
Biomedicines, 2025Nels cream achieved a similar reduction in inflammatory and noninflammatory lesion counts compared to 5% benzoyl peroxide in acne vulgaris patients, but caused significantly fewer side-effects such as peeling and dryness.
Clinical and Experimental Dermatology, 2000Topically applied coated and uncoated zinc oxide nanoparticles under flexing and massage are retained in the stratum corneum with no significant penetration into the viable epidermis and no cellular toxicity in human skin.
Nanomedicine, 2016Application of Echinacea purpurea cream and gel increased skin hydration up to 10.6 AU and 11.4 AU and decreased wrinkles by 9.47% and 14.92% without causing skin irritation in 10 healthy volunteers over 1 month.
International Journal of Cosmetic Science, 2010A new skincare formulation from Echinacea purpurea completely blocked the 40-60% reduction in skin nerve endings caused by UVA and UVB exposure in ex vivo human skin samples.
Cell Proliferation, 2012Topical application of Echinacea pallida root extract and its constituent echinacoside showed good anti-inflammatory and wound healing properties compared to E. purpurea and control in rats.
Journal of Ethnopharmacology, 2002
Why other sunscreens fit dry skin better
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.
