Ocean Cleanser
Mineral marine cleanser
5 fl oz / 150 ml
Description
Wake up your skin and your senses. This seaweed-infused gel cleanser effectively removes surface impurities and excess oils. Our pH-balanced formula uses lactic acid to gently exfoliate and help visibly refine pores without stripping skin. Delivers mineral-rich hydration for a radiant complexion you can see and feel.
Our Ocean Cleanser is primarily made with naturally derived ingredients and we don’t use any artificial colorants in the formula. Because of this, the color can vary from batch to batch and may even shift over time - this is completely normal and doesn’t affect the quality or effectiveness of the product. Similarly, since no synthetic fragrance is used, the scent may also vary due to the natural composition!View full product detailsScent profile

FAQs
Ocean Cleanser
Ocean Cleanser is a gel cream designed for normal or combination skin, removing surface impurities and excess oils while gently exfoliating to unclog pores. It delivers mineral-rich hydration for a clear, radiant complexion and boasts a pH-balanced formula with an invigorating citrusy scent.
Ocean Wave Cleanser is a gentle bi-phase makeup remover + cleansing oil that effectively dissolves makeup (including waterproof), impurities and excess sebum—without stripping skin. It’s the perfect first step in a double cleanse routine.
Ocean Cleansing Milk is a milky emulsion ideal for dry, sensitive, and mature skin types. It melts away dirt, debris, and makeup while moisturizing, smoothing, and soothing the skin, restoring its radiance. This formula is also pH balanced, fragrance-free, and dermatologist approved, ensuring it's safe for sensitive skin.
Ocean Cleansing Mudd is a clarifying cleanser that clears away excess oils without stripping the skin, purging pores of impurities. It leaves the skin feeling clean and refreshed with an invigorating scent of wild mint.
Avoid contact with the eyes. To remove eye makeup (even waterproof!), use our Ocean Wave Cleanser and Reusable Cotton Rounds.
For a lightweight hydrating routine: Massage Ocean Wave Cleanser into dry skin to dissolve makeup and impurities. Then, use Ocean Cleanser to round out your double cleanse. After rinsing, apply Hyaluronic Sea Serum to slightly damp skin. Follow with your favorite OSEA face moisturizer.
For your nighttime routine: After cleansing with Ocean Cleanser, apply Dream Night Serum and then follow with Dream Night Cream. Top it off with our nourishing Essential Hydrating Oil.
Hyaluronic Sea Serum
After cleansing with your favorite cleanser, like our bestselling Ocean Cleanser, follow with Sea Minerals Mist to prep skin and then apply a few drops of Hyaluronic Sea Serum to slightly damp face and neck. Allow to absorb. Seal in with your moisturizer of choice, like Seabiotic® Water Cream during the day and Dream Night Cream at night.
Our skincare products are made with naturally derived ingredients to provide the best benefits for your skin. Hyaluronic Sea Serum is fragrance free meaning there is no fragrance or essential oils added. However, you may detect a scent from some of the naturally derived ingredients in this formula.
Olfactory receptors (or sense of smell) differ from person to person so it is hard to describe what you might smell in a fragrance-free formula, but it could best be described as a bit “earthy” or “medicinal”. Please note the scent does not affect the product’s quality or efficacy.
Hyaluronic Sea Serum is our high-performance hydrating serum.
This fast-absorbing, hydrating serum is clinically shown to improve skin elasticity and visibly reduce fine lines & wrinkles. Two molecular weights of hyaluronic acid, seaweed and snow mushroom work together to help maintain optimal moisture levels. A burst of hydration for all skin types.
Dream Night Serum is our wrinkle smoothing serum.
This powerful formula works while you sleep to visibly reduce crow’s feet, fine lines, and even deeper wrinkles as you age. Algae-derived bio-retinol and two firming peptides combine to mimic the effects of retinol without irritation. Wake up to visibly smoother, firmer skin.
Seaglow Overnight Serum AHA Treatment is our exfoliating serum.
High-performance 9% AHA + 2% Phytic Acid treatment exfoliates to promote skin turnover, which evens tone and texture overnight. Nutrient-rich seaweed and Shiunko oil reinforce skin’s moisture barrier to reveal radiance. Wake up to clearer pores and a smoother, brighter complexion.

This cleanser is so refreshing, lightweight, even works well removing mascara (may still need to swipe some eye make-up cleaner after, depending if you use a havier eye aplication), one pump is all you need per use.

OSEA skincare changed my life. In 2018 I was on a work trip in Puerto Rico making social media content with Victoria Moronta and we both fell in love with these products the second they hit our skin. We spent a lot of time on the beach and these products soothed our skin like nothing ever has. I’ve never looked back, and my skin has never looked better. The ocean cleanser has been my go-to for removing light making and washing the grime of the day off my face. I look forward to the light refreshing scent and always follow it up with the seabiotic water cream to moisturize. I’m a loyal customer of 8 years and I truly believe this brand is run by good people with great values.
