OSEA is a clean skincare brand that uses natural and non-irritating ingredients. They prioritize naturally-derived ingredients, chosen for their safety and efficacy, and their formulas deliver results by using active ingredients at clinically validated levels. OSEA is committed to using vegan and cruelty-free ingredients, and all their products are vegan-certified by PETA and cruelty-free certified by Leaping Bunny International. They also prioritize sustainable packaging materials and have been packaging in glass since the 90s.

OSEAs main ingredient is seaweed, which is sourced from all around the world based on scientific data and has a myriad of benefits including anti-aging and mineralizing and moisturizing for healthier-looking skin. Some of the key ingredients in their products include Undaria algae, Japanese miru seaweed, red seaweed, brown seaweed, hyaluronic acid, and snow mushroom.

Positive aspects of OSEA include their commitment to clean, natural ingredients, sustainable packaging, and advocacy for better beauty laws. Their products are of high quality, with super creamy, rich, and potent formulations. OSEAs products are suitable for a variety of skin types, and they even have a quiz to help customers find the right products for their skin.

The only downside of OSEA is that their products are a bit on the higher end in terms of price, although they do offer trial sizes of many products.
