How To Use

Step 1 - Cleanse & Prep – Start with a freshly cleansed face. Follow with your regular toner or serum if desired.

Step 2 - Take 2 Pumps of sunscreen and spread evenly over face, neck, and exposed areas. Wait for a minute before you apply sunscreen post moisturiser to avoid piling.

Reapply for Protection – Reapply every 3hours, or immediately after sweating, swimming, or towel-drying. Provides protection at even UV Index 8-11

How It Works
  • Hydration & Barrier Function: Sodium Hyaluronate attracts and binds moisture to the skin, while Ceramides, Shea Butter, and Glycerine lock it in, reinforcing the skin’s protective barrier. This synergy ensures long-lasting hydration, prevents water loss, and keeps the skin soft, supple, and resilient.
  • Antioxidant Protection: Fucoidan, Green Tea Extract, and Coenzyme-Q10 deliver powerful antioxidant defense by neutralizing free radicals and reducing oxidative stress. Together, they protect against environmental damage, support collagen production, and slow down visible signs of aging such as fine lines and uneven tone.
  • Broad-Spectrum UV Protection: Micronized Zinc Oxide acts as a physical sunscreen, reflecting and scattering harmful UVA & UVB rays. Fucoidan further enhances its efficacy by protecting against long-term UVA damage and sunburn risk, even in extreme UV Index 8–11 conditions.
  • Exfoliation & Brightening: Phytic Acid binds and removes heavy metal pollutants from the skin, while Lactic Acid provides gentle exfoliation to promote healthy cell turnover. This combination brightens the complexion, improves skin texture, and complements the protective and hydrating benefits of the formula.
Ingridients
Sunscreen Ingredients
  • Micronized Zinc Oxide 13.5%: Mineral sunscreen agent that provides broad-spectrum protection by reflecting and scattering UV rays to prevent them from penetrating the skin. Its effectiveness is further enhanced by fucoidan, which adds natural UVA-blocking properties for a more powerful sunscreen defense.
  • Brown Algae Extract (Fucoidan): Derived from brown algae, is rich in antioxidants and has anti-inflammatory properties that protect the skin from environmental stressors while aiding repair and regeneration. Its antioxidant action further enhances the protective effects of green tea extract and Coenzyme Q10, creating a comprehensive shield against free radicals.
  • Plant-Based Ceramide Complex (Ceramide NP, Ceramide AP, Ceramide EOP, Phytosphingosine): Vital for maintaining the skin's barrier function and locking in moisture, protecting against environmental damage and water loss. It further enhances the hydration from sodium hyaluronate and the soothing benefits of shea butter, creating a strong, resilient skin barrier.
  • Sodium Hyaluronate: The sodium salt of hyaluronic acid, known for its powerful ability to retain moisture, keeping the skin hydrated, plump, and youthful. Its moisture-retaining properties further enhance the barrier function of ceramides and the protective qualities of zinc oxide, ensuring lasting hydration while shielding the skin from UV rays.
  • Red Raspberry Seed Oil: Rich in essential fatty acids and carries a natural SPF, offering additional UV protection along with anti-inflammatory and antioxidant benefits. When paired with zinc oxide, it boosts the sunscreen's overall protection while deeply nourishing the skin.
  • Green Tea Extract (Catechins): Rich in catechins, powerful antioxidants that protect the skin from UV radiation and environmental pollutants. Its antioxidant action works synergistically with fucoidan and Coenzyme Q10 to neutralize free radicals and reduce oxidative stress on the skin.
  • Coenzyme-Q10: A potent antioxidant that helps diminish fine lines and wrinkles by stimulating collagen production and protecting the skin from photoaging. Its anti-aging effects are further enhanced by sodium hyaluronate's deep hydration and ceramides' barrier-strengthening action, delivering comprehensive skin rejuvenation.
  • Phytic Acid: A natural chelating agent that removes heavy metals from the skin while offering antioxidant and brightening benefits. It works in harmony with lactic acid's exfoliating action and green tea extract's antioxidant power to promote a clearer, more radiant complexion.
  • Sorbitan Oleate: An emulsifier that blends oil and water components, giving the sunscreen a smooth and even texture. Working alongside cetearyl olivate and sorbitan olivate, it ensures a stable, easily spreadable formulation for consistent application and protection.
  • Caprylic/Capric Triglyceride: Derived from coconut oil and glycerin, acts as an emollient that softens and smooths the skin while improving the sunscreen's spreadability. It also boosts the moisturizing effects of shea butter and glycerin, leaving a non-greasy, hydrated finish.
  • Shea Butter: A natural fat from shea tree nuts, rich in vitamins A, E, and F, offering deep moisturization and anti-inflammatory benefits. Its nourishing properties work alongside sodium hyaluronate's hydration and ceramides' barrier support to keep the skin soft, supple, and protected.
  • Cetearyl Olivate and Sorbitan Olivate: Derived from olive oil, act as emulsifiers that create a smooth, stable formulation while improving the skin's ability to retain moisture. They also strengthen the emulsifying action of sorbitan oleate and ensure even delivery of active ingredients like zinc oxide and green tea extract across the skin.
  • Glycerine: A humectant that attracts moisture into the skin, keeping it well-hydrated and preventing dryness. It works synergistically with sodium hyaluronate and shea butter to deliver lasting hydration and maintain skin suppleness.
  • Glyceryl Monostearate: Functions as both an emulsifier and emollient, helping stabilize the sunscreen formulation while giving it a smooth texture. It complements the action of cetearyl olivate and sorbitan olivate, ensuring a consistent and stable formulation.
  • Phenoxyethanol: A preservative that protects the product from bacterial and mold growth, ensuring safety and longer shelf life. Working with other stabilizers, it helps maintain the sunscreen's integrity and effectiveness over time.
  • Lactic Acid: Works with emulsifiers like glyceryl monostearate to gently exfoliate the skin, promoting cell turnover and improving texture and tone. It also complements the brightening effects of phytic acid and the hydrating benefits of sodium hyaluronate, leaving the skin smoother and more radiant.
  • Xanthan Gum: A natural thickening agent that stabilizes the sunscreen formulation, ensuring even application. It works alongside emulsifiers like glyceryl monostearate to deliver a smooth, stable, and easy-to-apply texture.

Plus, our Antioxidant-rich complex (Fucoidan, CoQ10, Catechins, Raspberry Seed Oil) helps combat Oxidative Stress, supporting overall skin health, without any hidden risks Many chemical sunscreens contain endocrine-disrupting ingredients like Oxybenzone and Octinoxate, which can mimic hormones & affect the body's natural balance.

    We don't realise it but the harmful UV rays from the sun have the power to:

    • Burn & peel your skin off.
    • Cause permanent dark spots.
    • Fastrack ageing to the point of wrinkles at a very young age.
    • Become the cause of something as serious as skin cancer & tumours.

    How many types of UV rays are there? UV radiation can be divided into primarily three types based on wavelength:

    • UV-A (320-400 nm) can penetrate into the deeper layers of the skin called the dermis. It has the power to degrade its collagens & elasticity accelerating your skin’s ageing process & triggering wrinkle formation .
    • UV-B (280-320 nm) because of its shorter wavelength can penetrate the outer layer of the skin called epidermis. It can cause sunburns & can trigger the aging of this layer. In comparison, it comes with a larger risk of developing skin cancer.
    • UV-C (200-280 nm) does not make it to the earth’s atmosphere thanks to the Ozone Layer so it has no effect on our skin.

    “UV radiation affects the proteins in the corneodesmosomes & weakens the binding of the cells on the outermost layer of the skin making them detached. This damages the integrity of the skin that cannot be repaired by the body over a long time.” This can lead to your skin peeling after a sunburn.

    (Source: A Study by Zachary W.Lipsky)

    • Your sunscreen should be Broad Spectrum. This means it should protect you from both UV-A & UV-B rays.
    • Your sunscreen should not have harmful chemicals like Oxybenzone.
    • It should have a higher SPF.
    • It should have a higher PA Rating.

    There are majorly two categories of cream-based sunscreens:

    1. Mineral Based
    2. Chemical Based a.k.a Organic Sunscreens

    Chemical based sunscreens are not made up of organic-origin or plant-based ingredients. It's a myth. They're often called organic purely because the UV filter it uses is an organic compound.

    Because:

    • Better compatibility makes them cause less allergic reactions.
    • They decompose & therefore have negligible harm to the environment or marine life.
    • Unlike chemical sunscreens, these not just absorb but actually reflect & scatter UV rays resulting in dual protection.

    The ingredients to avoid include:

    • Oxybenzone (BP-3) (very harmful for your skin)
    • Octocrylene (OC)
    • Octinoxate or Ethylhexyl Methoxycinnamate (EHMC)

    As you know, Algae or seaweed is found underwater. Unlike land, it gets no protection from the shade of the trees or shrubs. Like any other plant, they also need water.

    A lot of UV rays penetrate the water along with sunlight. Over millions of years the algae have developed certain substances as defence mechanisms. These help them survive the harsh marine ecosystems.

    We @Erthe&Skkin have extracted those substances out of the brown algae or seaweed & infused them in our sunscreen to produce a groundbreaking innovation for the Indian skin.

    Fucoidan is one natural substance found in brown algae used in our innovative sunscreen formulation. Its photoprotective properties have proven miraculously effective in the often neglected UV-A radiation protection.

    Best mineral sunscreen

    The best mineral sunscreen. It takes little time to settle on skin after application. Once absorbed there is no white cast and my skin is fresh for whole day. I have oily skin bt it keeps my skin fresh looking and doesn’t reduce the glow on my face. I simply love this. Finally found my holy grail

    Recommended by my dermat

    I had carbon laser treatment for my acne and even skin tone, my doctor prescribed this sunscreen, I asked for known brand, but she insisted I use this , as it was SPF 45 only I was very skeptical but first thing it did not sting my eyes and skin , second with very little product , it’s a lot of protection as I reside in Rajasthan, third, this is sufficient for 1 month, I started to use everyday as it’s light weight n easy on skin, it’s a 10/10
