Can Seawater Help You Get Rid of Acne?

The quest for clear, vibrant skin has led many to the natural world, with remedies ranging from herbal concoctions to the mineral-rich waters of our seas.

Sea water, in particular, has long been hailed for its purported skin-healing properties, especially when it comes to acne.

And if you are reading this article, chances are you have heard someone say that taking a dip in the ocean will clear up your skin.

However, is there really any truth behind this claim?

As an esthetician, an avid swimmer who lives by the sea, and a former acne sufferer, I have done my research on this topic and have some insights to share.

So, let’s dive deeper into the world of seawater and discuss its potential as an acne remedy, scrutinizing both the scientific evidence and the possible risks associated with it.

Can Sea Water Get Rid of Acne?

The belief that seawater can soothe and potentially cure acne stems from several key properties:

Natural Antimicrobial Properties: The salt content in seawater is thought to have antimicrobial effects, potentially reducing the overgrowth of the acne-causing bacteria.

Mineral Benefits: Seawater is rich in minerals like magnesium, calcium, and potassium, which are believed to support skin health and reduce inflammation associated with skin conditions such as acne.

Historical and Anecdotal Evidence: There are numerous historical references and personal testimonies claiming sea water’s healing effects on the skin.

However, despite these promising attributes, the reality is;

Seawater is not a cure for acne.

The reasons for this are multifaceted and rooted in both scientific research and practical considerations.

The Scientific Perspective

Limited Research: There’s a scarcity of scientific studies directly linking seawater with acne improvement. This lack of evidence makes it difficult to substantiate the claims of its efficacy.

Mechanism of Action: While the antibacterial properties and mineral content of seawater could theoretically benefit acne-prone skin, the actual impact of these factors is not well-documented in scientific literature.

Can Seawater Cause Acne?

Contrary to the belief that seawater can alleviate acne, some circumstances suggest it can actually contribute to the problem.

Here’s how seawater can cause or exacerbate acne:


Seas are not immune to pollution, and chemicals in the air, as well as those being released in the water, can compromise its quality, introducing harmful bacteria and impurities that exacerbate skin conditions such as acne.

Salt Content:

While sea salt has been lauded for its exfoliating and healing properties, excessive exposure can disrupt your skin’s barrier and change its pH balance, causing dryness and irritation and exacerbating inflammatory conditions such as acne.

Sun Exposure:

While a little bit of sunshine can have beneficial effects on the skin, prolonged exposure to the sun’s UV rays without proper protection can increase inflammation and worsen acne.

Pair this up with skin that’s damaged from exposure to excessive salinity in seawater, and you’ve got a recipe for disaster.


Spending long hours swimming and frolicking in seawater can also cause dehydration, leading to dryness and irritation of the skin, which can contribute to acne flare-ups.

These factors highlight the importance of caution and being mindful of potential risks when relying on “remedies” such as seawater for acne treatment.

Can Sea Water Get Rid of Hyperpigmentation?

Can Sea Water Get Rid of Hyperpigmentation

The simple answer is no.

Hyperpigmentation is a complex skin condition that occurs due to inflammation in the area and often requires targeted treatments that address the underlying causes, which is usually damage to the skin’s melanocytes.

While seawater may have some anti-inflammatory properties, it is not a targeted solution for addressing hyperpigmentation.

Furthermore, excessive sun exposure and salt content in seawater can actually worsen hyperpigmentation by further damaging the skin and prolonging healing time.

The Best Alternative Treatments for Acne

The Best Alternative Treatments for Acne

While exploring the potential of seawater in acne treatment, it’s essential to also focus on more reliable and scientifically backed alternatives.

These include adjustments in diet, lifestyle habits, and targeted skincare treatments that have shown effectiveness in managing acne.


The link between diet and acne is complex, but certain foods can influence internal inflammation and, by extension, acne severity.

Here’s a look at what to include and what to avoid:

Foods to Eat:

• Omega-3 fatty acids (found in fish like salmon, chia seeds, and walnuts) can reduce inflammation.

• Antioxidant-rich fruits and vegetables (berries, leafy greens) help neutralize free radicals and reduce inflammation.

• Probiotic-rich foods (yogurt, kefir, sauerkraut) support gut health, which can impact skin health.

• Whole grains and foods with a low glycemic index can stabilize blood sugar levels, potentially reducing acne flare-ups.

Foods to Avoid:

High glycemic index foods (white bread, sugary snacks) can spike blood sugar levels and may exacerbate acne.

• Dairy products have been linked to acne in some people, possibly due to intolerance to hormones present in milk.

• Foods high in saturated and trans fats (fast food, processed snacks) can increase inflammation, potentially worsening acne.

Lifestyle Habits

Certain lifestyle habits can exacerbate acne while making simple swaps for healthier alternatives can improve skin health:

Reduce Stress: High-stress levels can increase the production of hormones such as cortisol that worsen acne.

Get Enough Sleep: Lack of sleep can affect hormonal balance and skin health. Aim for 7-9 hours of quality sleep per night.

Avoid Smoking: Smoking can worsen acne by increasing inflammation and reducing blood flow to the skin.

Hydration: Staying well-hydrated helps maintain clear skin by supporting detoxification and nutrient delivery to skin cells.


Effective acne management often involves topical treatments that target the different factors contributing to acne.

Here are some of the best treatments:

Salicylic Acid

Salicylic acid is a beta-hydroxy acid (BHA) that’s particularly effective for removing blackheads and whiteheads by dissolving cellular debris inside the pores and preventing it from causing inflammation that leads to acne.

Mandelic Acid

Mandelic acid is an alpha-hydroxy acid (AHA) known for its gentle exfoliating properties.

It’s suitable for sensitive skin types and works by accelerating cell turnover, improving skin texture, and reducing acne scars.

Its antibacterial qualities also make it beneficial for treating active acne.

Benzoyl Peroxide

Benzoyl peroxide infuses the pores with oxygen and destroys the airless environment the acne-causing bacteria prefer to live in.

It’s available in various concentrations, making it suitable for mild to severe acne.


Retinoids, particularly adapalene and tretinoin, reduce acne lesions by accelerating cellular turnover and preventing the clogging of pores.

Additionally, these derivatives can also improve the appearance of acne scars, including hyperpigmentation and skin texture over time.

However, due to their potency, retinoids should be introduced gradually into a skincare routine to minimize irritation.
