Lovi Assistant explains
- Excellent suitability for your normal skin is provided by Parachlorella Beijerinckii Exopolysaccharides and Tocopheryl Acetate, which offer antioxidant activity and barrier repair to address pigmentation concerns.
- Arctostaphylos Uva-Ursi Leaf Extract and Glycyrrhiza Glabra Root Extract further support brightening benefits, enhancing the product's relevance for your main goal.
- The product is safe for your normal skin due to the absence of harsh ingredients and the inclusion of soothing Glycyrrhiza Glabra Root Extract.
How to apply
- Apply your AM sunscreen as the final step of your morning skincare routine. Reapply every two hours when exposed to direct sunlight.
- Apply after your moisturizer and before applying any makeup. Make sure it is the very last step of your daytime skin care routine.
- Gently spread a generous amount evenly across your face and neck. Avoid rubbing too harshly to keep the protective layer even.
- Apply on completely dry skin after your moisturizer has fully absorbed. This ensures the protective barrier sits evenly on your face.
- Avoid direct contact with your eyes. Do a patch test before your first full application to ensure no irritation occurs.

What the research says
Vitamin E in O/W and W/O emulsions significantly increased stratum corneum hydration and enhanced water-binding capacity, with an optimum concentration of 5%.
Arzneimittel-Forschung, 1998Co-encapsulation of alpha-tocopherol and alpha-tocopheryl acetate in nanostructured lipid carrier gel formulations significantly enhanced moisture retention up to 68% and improved skin elasticity in human volunteers compared to a solution gel.
Scientific Reports, 2025Encapsulation of alpha arbutin in an optimized ethosomal gel significantly improved skin melanin reduction, moisture content, and elasticity in human volunteers compared to conventional formulations.
Heliyon, 2023Replacing 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.
