low molecular hyaluronic acid, sodium hyaluronate, ceramide np, panthenol, and madecassoside

Hyaluronic acid is a glycosaminoglycan naturally present in the dermis. When applied topically, low-molecular-weight HA penetrates beyond the surface to bind water molecules between skin cells, creating a reservoir effect that keeps skin plump from within. In this sunscreen, Hyaluronic Acid targets uneven texture, delivering delivers deep, lasting hydration that keeps skin plump throughout the day with consistent use.

Hyaluronic Acid
draws and locks moisture deep within the skin, holding up to 1000x its weight in water
Ceramides
restore the lipid mortar between skin cells to lock in moisture and keep irritants out
Allantoin
neutralizes irritation signals while promoting gentle cell regeneration
Panthenol (Vitamin B5)
penetrates deep to hydrate from within and repair compromised barrier tissue
Madecassoside
the most potent anti-inflammatory fraction of centella asiatica for rapid calming

Ingredients

Low molecular hyaluronic acid, ceramide NP, panthenol, betaine, and cica-derived support focus on water retention and comfort.

This serum is built for dehydrated skin that also needs comfort. Low molecular hyaluronic acid and sodium hyaluronate help hold water close to the skin so it looks fuller, softer, and less tight. Support ingredients such as betaine, panthenol, allantoin, and ceramide NP matter just as much because hydration lasts better when the barrier feels calm and resilient. The cica-side components, including madecassoside and related centella compounds, help the formula feel gentler on skin that is easily irritated or overworked. In a light serum texture, the goal is quick, repeatable moisture that layers well under other products instead of sitting on top. The expected result is not a glossy heavy finish, but a better moisture reserve, a smoother texture, and skin that feels more comfortable through the day.

Questions & answers

Two finger-lengths for the face and neck. Most people under-apply sunscreen, which reduces the effective SPF.
Some users find this hydrating enough on its own. For dry skin, a light moisturizer underneath is recommended.
SPF protection degrades with sun exposure, sweat, and friction. Reapply every 2 hours during direct sun exposure for consistent protection.
Sunscreen significantly reduces UV-induced tanning and damage but does not block 100% of UV rays. Consistent application minimizes cumulative sun damage.
Yes, this formula is developed to be compatible with all skin types dealing with uneven texture. If you have very reactive skin, patch test on the inner arm before full application.
Mineral-based sunscreens are generally considered safe. Check the ingredient list for your specific concerns and consult a dermatologist if needed.
Hyaluronic Acid draws and locks moisture deep within the skin, holding up to 1000x its weight in water. Consistent daily use is key to seeing the full benefits.
Check the active ingredients list. Chemical filters absorb UV rays; mineral filters (zinc oxide, titanium dioxide) reflect them. Some formulas combine both.
Store in a cool, dry place away from direct sunlight. Use within 12 months of opening for optimal freshness and efficacy.
Korean sunscreen formulations prioritize both protection and cosmetic elegance, delivering high SPF with minimal white cast, lightweight texture, and skincare benefits.
