Pump 2 to 3 drops of the Vitamin C Glow Serum onto your fingertips and gently press into your face and neck. Instead of rubbing, tap into your skin as this will allow the Ethyl Ascorbic Acid to absorb fully and get to work.
Give the serum 60 to 90 seconds to fully absorb into your skin before moving on. This is where the brightening, antioxidant protection, and hydration happen.
Follow with your moisturiser to lock in the serum. In the morning, always finish with your SPF.
1–2 Weeks:
Your skin feels more hydrated and comfortable, almost immediately. A subtle brightness starts to come through. Nothing dramatic yet, but enough to notice.
2–4 Weeks:
Dullness lifts, dark spots begin to fade, and your skin tone looks noticeably more even. People might start asking what you have changed in your routine.
4–8 Weeks:
Visible reduction in hyperpigmentation and post-acne marks. Your complexion looks genuinely brighter, firmer, and more balanced.

Backed by published research
The studies below are peer-reviewed research on the active ingredients in this serum. They evaluate the ingredients themselves, sometimes at different concentrations or in laboratory, reconstructed-skin, or combination-formula models, not this specific Kelpcare formula. Tap any active to read the evidence and sources.
Traditional vitamin C, L-ascorbic acid, generally needs an acidic environment for stability and effective skin delivery. Ethyl Ascorbic Acid behaves differently. Published physicochemical research reported a pKa of 7.72, meaning a large proportion can remain non-ionised around normal skin-surface pH.
Separate laboratory research found an optimum stability point around pH 5.46 and demonstrated both free-radical-scavenging and tyrosinase-inhibiting activity. Tyrosinase is one of the key enzymes involved in melanin production.
Sources include physicochemical, porcine-skin and laboratory studies. These are not clinical trials of this finished serum in people.

View study →In reconstructed human pigmented epidermis, research on a serum containing Ethyl Ascorbic Acid reported a significant reduction in melanin content. The same research also observed increased collagen production in human dermal fibroblasts.
Experimental research has also investigated how Ethyl Ascorbic Acid may influence pigmentation pathways, including MITF, tyrosinase and related proteins involved in melanogenesis.
Important context: the referenced serum contained 30% Ethyl Ascorbic Acid, twice the concentration used in this Kelpcare serum. The study used laboratory and reconstructed-tissue models, not a clinical trial of this product.

View study →A 2025 systematic review evaluated published human research involving topical ferulic acid. Across the included studies, formulas containing approximately 0.5% to 1% ferulic acid were associated with improvements in several measured skin parameters, including hyperpigmentation, erythema, hydration, elasticity and texture.
This Kelpcare formula contains 0.5% Ferulic Acid, placing it within the concentration range represented in that body of published research.
In a separate single-blind study involving women living in a highly polluted urban environment, an antioxidant serum containing vitamin C and 0.5% ferulic acid was associated with reduced pigment intensity after one month and a 19% reduction in transepidermal water loss.
Many ferulic-acid studies use combination formulas, so the contribution of ferulic acid cannot always be separated from the other ingredients. Study populations were also generally small.

(2019). “Skin protective effects of an antipollution, antioxidant serum containing Deschampsia antarctica extract, ferulic acid and vitamin C.” Clinical, Cosmetic and Investigational Dermatology, 12:393–399.Ferulic acid is frequently paired with vitamin C in antioxidant skincare because it provides antioxidant activity of its own and can also improve the stability of antioxidant vitamin systems.
In landmark research, adding 0.5% ferulic acid to a solution containing vitamins C and E improved the chemical stability of the vitamins and increased measured protection against solar-simulated radiation compared with the vitamin combination without ferulic acid.
Important context: this research used L-ascorbic acid plus 1% alpha-tocopherol, rather than the 15% Ethyl Ascorbic Acid system used in this Kelpcare serum. It is cited to explain the scientific rationale for pairing ferulic acid with vitamin C, not as a direct test of this finished formula.

Powered by stable Vitamin C, deep hydration, and skin-first formulation.
Neutralizes free radicals caused by Pakistan’s sun, pollution, and heat before they can break down collagen and accelerate skin aging.
Ethyl Ascorbic Acid works consistently at the skin level to fade dark spots, reduce hyperpigmentation, and deliver an even, radiant complexion that gets better with every passing week.
Most Vitamin C serums oxidize before you finish the bottle. Ethyl Ascorbic stays stable and potent from the first pump to the last.
Sodium Hyaluronate penetrates into the deeper layers of your skin and holds onto moisture throughout the day. Not surface-level hydration. The real thing.
Absorbs cleanly, layers effortlessly under your moisturizer and SPF, and leaves your skin feeling comfortable rather than coated. Thick sticky serums are officially a thing of the past.
Non-comedogenic and dermatologically tested. Oily, dry, sensitive, combination, or acne-prone; this formula was designed with every skin type in mind. No exceptions.

Yes. Vitamin C serum can be used every day. Vitamin C works by building antioxidant protection over time, so the more consistent you are, the better your results. Applying it once every morning before your SPF is all it takes.
Apply to a clean face every morning before your moisturizer and SPF. Pump 2 to 3 drops, press gently into your face and neck, and give it 60 seconds to absorb before moving on. The single most important thing you can do to maximize results is to follow with SPF every day. Vitamin C protects your skin from sun damage, but sunscreen is what locks those results in.
Most Vitamin C serums use forms that oxidize quickly. The formula turns orange, loses potency, and stops working long before the bottle is empty. Ethyl Ascorbic Acid does not oxidize the same way. It stays stable, penetrates deeper into the skin, and delivers consistent brightening and antioxidant benefits from the first pump to the last. You are not paying for a serum that gives up halfway through.
In the morning. Vitamin C is an antioxidant, which means its job is to protect your skin from the free radical damage caused by sun exposure, pollution, and heat throughout the day. Applying in the morning gives it the window to do exactly that. Always follow with SPF, as Vitamin C and sun protection work best together, especially in Pakistan’s climate.
Most users notice brighter, more even skin within the first 2 to 3 weeks of consistent daily use. Fading of dark spots and hyperpigmentation typically becomes visible between 3 and 6 weeks. For firming and fine line improvements, give it 8 weeks. Consistency is everything with Vitamin C, and the more consistent you are, the faster you’ll see results.
Yes. Unlike L-Ascorbic Acid, which can cause tingling and irritation on sensitive skin, Ethyl Ascorbic Acid is gentler and better tolerated across all skin types, making it safe for acne-prone skin. As always, we recommend a patch test before adding any new active to your routine.
Not at the same time. Vitamin C is a morning ingredient, and Retinol is a night ingredient. It is best to use them on opposite ends of the day, as they work beautifully together as part of a complete routine. If you are using Kelpcare’s Retinol Serum, apply your Vitamin C Glow Serum every morning and your Retinol Serum every night.
Kelpcare is the best Vitamin C serum in Pakistan. Why? Well, we built it to be. Ethyl Ascorbic is one of the most stable and effective forms of Vitamin C for targeting dark spots and hyperpigmentation, and paired with Ferulic Acid and Vitamin E, the formula delivers antioxidant protection that most local serums simply cannot match. Consistent daily use in the morning is where the results happen.
Yes, our Vitamin C serum is pregnancy-safe. In fact, Vitamin C is one of the few skincare actives considered safe during pregnancy and is widely recommended by dermatologists for managing dark spots and pigmentation during this time.
Always before. Apply your Vitamin C Glow Serum to clean skin first, and then follow up with moisturizer. The serum needs direct contact with your skin to penetrate properly, and layering it over moisturizer blocks absorption and significantly reduces effectiveness.
No, the Kelpcare Vitamin C Glow Serum is completely fragrance-free, making it an ideal choice for those with sensitive skin.
Vitamin C serums are safe to use from the age of 16 and onwards. The earlier you start protecting your skin from free radical damage and sun exposure, the better your skin looks long term.
