This fit is calculated for the concerns frequently associated with dry sensitive skin: flakiness, tightness, redness, 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 humectant action of glycerin, but it lacks sufficient emollient ingredients to fully address dryness.
- The product provides excellent UV protection with titanium dioxide and zinc oxide, which is beneficial for all skin types.
How to apply
- Use your sunscreen as part of your AM routine every morning. Reapply every two hours when exposed to the sun.
- Apply the sunscreen after your moisturizer as the final step of your morning skincare routine.
- Gently press a coin-sized amount of sunscreen evenly into your skin, and avoid rubbing it harshly. Let it set for a minute before going outdoors.
- Since your skin is sensitive , apply the sunscreen over your dry moisturizer to ensure better comfort and protection.
- Always do a patch test before your first use and avoid direct contact with the eyes.
People Say
★4.7Overall rating based on 200+ reviewsUsers with oily and combination skin highly praise this sunscreen for its ultra-lightweight, fluid texture that dries down to a soft matte finish without feeling greasy. It layers beautifully under makeup and provides strong protection.

Questions and answers
How well does Algenist Sublime Defense work for dry sensitive skin?
This product works for dry skin with glycerin helping hold moisture, though dry skin needs more rich smoothing ingredients. It provides good sun protection with titanium dioxide and zinc oxide that is unlikely to irritate sensitive skin.
Clinical, Cosmetic and Investigational Dermatology, 2017Skin Pharmacology and Applied Skin Physiology, 2001
Which ingredients make this fluid a good fit for dry sensitive skin?
Glycerin helps make this fluid an average fit for your dry sensitive skin through its hydrating action, while titanium dioxide and zinc oxide provide sun protection. However, a product of this type needs richer softening ingredients to fully address dryness and keep sensitive skin comfortable.
Clinical, Cosmetic and Investigational Dermatology, 2017Skin Pharmacology and Applied Skin Physiology, 2001
What does Octinoxate do for dry sensitive skin?
Octinoxate helps protect dry sensitive skin from sun damage by absorbing UV rays, though because it can sometimes cause irritation, encapsulation may make it safer and more comfortable to wear. A product of this type needs soothing, deeply hydrating ingredients and a gentle, fragrance-free formula to keep dry sensitive skin soft and calm.
International Journal of Nanomedicine, 2013Journal of Cosmetic Science, 2008
What does Titanium Dioxide do for dry sensitive skin?
Titanium dioxide acts as a physical shield on the skin surface to block UV rays without irritating dry sensitive skin. Because it sits on the outer layer rather than absorbing deeply, it is unlikely to cause allergic reactions or clog pores.
Skin Pharmacology and Applied Skin Physiology, 2001Current Problems in Dermatology, 2021
Where does this fluid go in a skincare routine for dry sensitive skin?
This fluid goes in the morning routine as a moisturizing sunscreen, right after your soothing toner. Dry skin needs rich softening ingredients and heavy moisturizing oils to stay smooth and fully comfortable.
Can I use this fluid with retinol, and in what order?
You can use this fluid in the morning after applying your retinol treatment once it has fully absorbed, or simply wear the fluid on its own during the day to protect your skin. This sunscreen includes glycerin to help hold in moisture, but dry skin of this type generally needs richer, softening ingredients to stay truly smooth and comfortable.
How often should I use this fluid?
You can use this sunscreen fluid every morning as part of your daily routine to protect against UV rays. To fully care for dry sensitive skin, this type of product also needs rich softening ingredients that lock in moisture and smooth rough patches.
Skin Pharmacology and Applied Skin Physiology, 2001International Journal of Cosmetic Science, 2000
Can this fluid clog pores, cause breakouts or purging for dry sensitive skin?
This fluid is unlikely to clog pores or cause breakouts on dry sensitive skin, as its physical sunblock minerals stay safely on the skin surface without soaking in. However, because it lacks rich smoothing ingredients, dry skin of this type needs added moisturizing oils or butters to stay fully soft and comfortable.
Skin Pharmacology and Applied Skin Physiology, 2001International Journal of Cosmetic Science, 2000
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, 2017Topical application of micronised titanium dioxide results in no dermal absorption, with the particles being deposited solely on the outermost surface of the stratum corneum.
Skin Pharmacology and Applied Skin Physiology, 2001Microfine 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 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, 2011Replacing 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, 2006Hyaluronic acid-grafted titanium dioxide nanoparticles increased SPF from 13.3 to 19.1 while demonstrating low photocatalytic activity, exceptional thermal stability with >95% SPF retention, enhanced moisturization with >80% hydration retention, and minimal cytotoxicity with 88.5% cell viability in HaCaT keratinocytes compared to unmodified nanoparticles.
International Journal of Biological Macromolecules, 2025Topical 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.
