In Your Heart Aqua Marine Sunscreen

In Your Heart Aquamarine Sunscreen SPF50+ PA++++ 50ml is a high-performance, daily chemical sunscreen engineered to deliver broad-spectrum UV protection while infusing the skin with long-lasting marine moisture. Manufactured in South Korea by Whitecos Pharm Co., Ltd. for In Your Heart Corp., this triple-functional formula targets UV defense, tone brightening, and anti-aging care in a single lightweight application.

At the center of the formula is a specialized 10-Seaweed Marine Complex—combining Undaria Pinnatifida, Laminaria Japonica, Spirulina Platensis, Fucus Vesiculosus, Ecklonia Cava, and Giant Kelp extracts. These marine botanicals protect against environmental irritants while delivering vital trace minerals and amino acids. Fortified with a 5-ceramide barrier complex (NP, NS, AS, AP, EOP), Onsen-Sui (hot spring water), and skin-brightening Niacinamide, this sunscreen applies freshly like a lightweight moisturizer without leaving any sticky residue or white cast.

How It Works & Key Benefits

• Broad-Spectrum UV Protection: Combines advanced organic UV filters (Homosalate, Ethylhexyl Salicylate, Avobenzone, Ensulizole, Tinosorb S) to absorb UVA and UVB rays, preventing sunburn and photoaging.

• Marine Irritation Shield: 10 seaweed extracts deliver marine polysaccharides and minerals to soothe skin irritation and prevent moisture loss during sun exposure.

• 5-Tier Ceramide Barrier Support: Ceramides NP, NS, AS, AP, and EOP replenish intercellular lipids to prevent transepidermal water loss (TEWL).

• Brightening & Anti-Wrinkle Care: Niacinamide balances skin tone and clarifies dullness, while Adenosine supports skin elasticity and minimizes fine lines.

• Weightless Daily Wear: Formulated with porous silica and non-greasy emollients to provide a smooth, comfortable finish suitable for daily use under cosmetics.

Core Active Ingredients & What They Do

• Organic UV Filter Complex (Homosalate, Ethylhexyl Salicylate, Butyl Methoxydibenzoylmethane, Phenylbenzimidazole Sulfonic Acid, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine): A photostable chemical filter array that provides comprehensive, broad-spectrum defense against burning UVB and aging UVA rays.

• 10 Marine Seaweed Extracts (Undaria Pinnatifida, Laminaria Japonica, Spirulina Platensis, Fucus Vesiculosus, Dunaliella Salina, Ecklonia Cava, Algae Extract, Codium Fragile, Sargassum Fulvellum, Macrocystis Pyrifera / Kelp): Deliver concentrated ocean bio-actives to shield against external environmental stressors and replenish deep cellular moisture.

• 5-Ceramide Matrix (Ceramide NP, Ceramide NS, Ceramide AS, Ceramide AP, Ceramide EOP): Skin-identical lipids that rebuild the damaged barrier, improve moisture retention, and protect against dehydration.

• Niacinamide (Vitamin B3): Brightens uneven skin tone, regulates surface sebum excretion, and supports ceramide synthesis.

• Adenosine: Functional anti-aging active that stimulates collagen production and softens fine expression lines.

• Onsen-Sui (Hot Spring Water): Soothing thermal mineral water that calms erythema and relieves environmental heat irritation.

• Multi-Depth Hyaluronic Acid Array (Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate Crosspolymer): Binds moisture across superficial and deeper epidermal layers for lasting suppleness.

• Allantoin & Tocopheryl Acetate: Soothe micro-inflammation and provide essential antioxidant protection against free radical damage.
