Just when it seems like every possible ingredient has already been bottled and shelved, something new makes me pause. This season, it is sea moss—a nutrient-dense red algae that’s quietly becoming skincare’s next fixation. Lauded for being used in traditional Chinese medicines for its cooling properties for centuries, the algae has now found a new home in supplements and skincare shelves. As slimy and uncanny the texture may be, if the likes of Bella Hadid and Kim Kardashian are falling for it, you know it’s got power. From boosting your immune system, curing in ammation, locking in moisture to offering an overall protein boost, this ingredient claims to do it all, and here’s how the experts break down what it can and can’t deliver.

STANCE IN SKINCARE

In this sea of marine skincare ingredients, sea moss is taking the lead, courtesy of all the claims of being an attractive superfood for skin. “Sea Moss (Irish Moss, Chondrus crispus) has gained hype in the cosmeceutical and medical-grade skincare space because it bridges clinical science with the rising demand for marine botanicals,” explains Dr Sukhsagar Ratol, dermatologist at Ceuticoz. “Sea Moss contains 92 of 102 essential minerals, vitamins (A, E, K, B-complex), amino acids, antioxidants, and omega-3s.” This rich nutrient count is what makes it a versatile marine bioactive with real potential and visible impact on skin when used in compatible formulations.

Similar to other underwater wonders, even sea moss holds a reputation for providing a glass-like glow. “Think of it as the more soothing, moisture-balancing cousin among marine superfoods,” says Dr Jamuna Pai, cosmetic physician, author, and founder of SkinLab. “While spirulina and chlorella are both excellent for detoxification and antioxidant support, sea moss stands out for its gel-like texture and high mucilage content, which provide superior hydration and barrier repair.”

A SUPERFOOD?

One of the many claims backing sea moss is that it works inside-out. “Sea Moss is impactful as a supplement for whole body wellness and long-term skin health,” shares Dr Ratol. Consumed in powder or gel-like form, the ingredient is said to have an edge in the wellness industry today. “Beyond skincare, its iodine content could support healthy thyroid function, and its prebiotic properties aid gut health—all of which contribute to better skin from within,” Dr Pai adds.

According to celebrity dietician Kavita Devgan, this nutrient-dense functional food has many pluses. “It can work as a natural appetite regulator as it increases the feeling of fullness. It also delivers multiple antioxidants like vitamin C, zinc, and prebiotics, hence is good for the gut. The ingredient is also anti-inflammatory, particularly good for liver and heart health, and it’s loaded with magnesium, so a great aid for insomniacs,” she asserts.

FINAL WORD

Sea moss may be more than just a passing trend in skincare, but can it be crowned as the next big miracle? Despite its benefits, the ingredient is still awaiting stronger clinical evidence to validate the long-term efficacy of its topical and nutritional benefits. “I see sea moss as a supportive ingredient—especially for dehydrated, sensitive and/or irritated skin. It’s not a miracle cure, but it complements a good skincare routine beautifully. As with any natural ingredient, formulation and concentration matter more than the ingredient alone,” Dr Pai reminds us.

Likewise, even while consuming it, a little caution goes a long way, believes Devgan. She advises against taking it arbitrarily. “Check with your dietician or doctor, as it might interfere with certain medications like blood thinners, blood pressure medications. It contains excessive iodine, so those with thyroid disorders must be really careful with it. Also, choose carefully and opt only for the organic ones that are lab tested by a third party,” she concludes.
