PRODUCT INFORMATION

Core is crafted to simplify your skincare routine without compromising on performance. This multi-correction serum targets dullness, uneven skin tone, barrier damage, and early signs of aging in a single, high-performance formula.

40% Birch Sap Juice forms the foundation of the formula, delivering deep hydration while soothing, strengthening, and replenishing skin with naturally occurring amino acids, minerals, enzymes, and antioxidants.

At the heart of Core is 5% Ethyl Ascorbic Acid, a stable and highly bioavailable form of Vitamin C that works alongside Tranexamic Acid and 5% Niacinamide to visibly reduce dark spots, improve clarity, and promote a brighter, more even-looking complexion. This synergistic combination helps address post-inflammatory pigmentation, sun-induced discoloration, and overall skin dullness.

Ceramide NP and Beta-Glucan help rebuild and reinforce the skin barrier, improving resilience, moisture retention, and reducing sensitivity caused by environmental stressors.

Photolyase, an advanced DNA-repair enzyme, helps support the skin’s natural recovery process from UV-induced damage, while Acetyl Tetrapeptide and Matrixyl 3000 encourage collagen production to improve skin firmness, smooth texture, and soften the appearance of fine lines over time.

Whether you're targeting pigmentation, dehydration, barrier damage, or early signs of aging, Core adapts to your skin’s changing needs—working daily to keep skin brighter, stronger, smoother, and visibly healthier with every use.

Core is your shortcut on busy days — the one serum that covers breakouts, dullness,
and early lines without needing a lineup of bottles.

Because it delivers results across every concern, with a texture that feels effortless to use daily.

Q: Can I use Core on oily skin?
Yes. Core is a lightweight, fast-absorbing serum designed to suit all skin types, including oily and acne-prone skin, without leaving any residue.

Q: I’ve never used active serums before. How often should I use Core?
Core can be used once or twice daily, depending on your skin’s tolerance. If you’re new to active ingredients, start with once a day and gradually increase. You may also consult a dermatologist before introducing new actives into your routine.

Q: Can I use Core in place of a moisturiser?
No. Core is not a replacement for a moisturizer. Apply Core before your moisturizer — this helps the serum absorb effectively while the moisturizer seals in hydration.

Q: Can I apply makeup on top of Core?
Yes. Core absorbs quickly and leaves the skin smooth, making it an excellent base under makeup.

Q: What is the difference between Core and Glow Armor?
Core is a treatment serum formulated with high-performance actives to target concerns like texture, clarity, and skin health. Glow Armor SPF 50+++ is a lightweight, broad-spectrum sunscreen designed to protect your skin from UV damage.

Curious Minds

Frequently Asked Questions

Does Core help with acne?

Yes, Core is formulated to help support acne-prone skin while keeping the skin balanced and hydrated.

Its combination of niacinamide, panthenol, vitamin C derivatives and barrier-supporting humectants helps calm visible redness, reduce excess oil imbalance and support postbreakout recovery. The lightweight hydrating formula also helps prevent the dehydration that can sometimes trigger increased oil production and congestion.

While Core works well as a daily balancing serum for supporting clearer, healthier-looking skin over time.

Does Core help with hyperpigmentation?

Yes. Core is designed to help improve uneven skin tone and post-breakout marks through a balanced blend of brightening and skin-supporting ingredients.

The formula combines niacinamide and vitamin C derivatives to help visibly brighten dull skin, support a more even complexion and gradually reduce the appearance of pigmentation over time. Rather than relying on overly harsh actives, Core focuses on consistent daily support while helping maintain skin comfort and barrier health.

With regular use, skin appears brighter, smoother and more balanced.

Does Core help with fine lines and early signs of aging?

Yes. Core contains peptides, niacinamide and deeply hydrating humectants that help support smoother, healthier-looking skin over time.

Hydrated skin naturally appears plumper and more supple, while peptides help support skin elasticity and overall skin resilience. Combined with antioxidant-rich ingredients and moisture-supporting actives, Core helps improve skin texture and reduce the appearance of early fine lines caused by dehydration and environmental stress.

The result is skin that looks fresher, healthier and more refined with consistent use.

Is Core suitable for dry and dehydrated skin?

Absolutely. Core is especially beneficial for dry and dehydrated skin because it focuses heavily on long-lasting hydration and barrier support.

The formula contains 8% humectants and emollients including hyaluronic acid, polyglutamic acid, glycerin and squalane, which help attract and retain moisture within the skin. Combined with 40% Birch Sap Juice and soothing ingredients like panthenol, Core leaves skin feeling soft, plump and comfortably hydrated without heaviness.

With regular use, skin feels smoother, healthier and more resilient against moisture loss.

Is Core suitable for oily and acne-prone skin?

Yes, Core is designed to hydrate and balance oily skin without making it feel greasy or overloaded.

Many oily skin types are actually dehydrated underneath, which can lead to increased oil production and congestion. Core helps replenish hydration while niacinamide supports oil balance and overall skin clarity.

Its lightweight serum texture absorbs comfortably into the skin, leaving it hydrated, balanced and fresh without a sticky finish.

Is Core suitable for combination skin?

Yes. Core works very well for combination skin because it delivers hydration without heaviness.

Dryer areas benefit from deep moisture support through humectants and emollients, while oilier areas remain comfortable thanks to the lightweight, breathable texture. The formula helps maintain overall skin balance, leaving skin feeling soft, hydrated and comfortable throughout the day.

Is Core suitable for sensitive skin?

Yes, Core is formulated to remain gentle and supportive even for sensitive skin types.

Ingredients like Birch Sap Juice, panthenol, squalane and hydrating humectants help soothe and support the skin barrier while delivering active ingredients in a balanced, non-aggressive way. The formula focuses on strengthening and hydrating the skin rather than overwhelming it with overly strong actives.

Core is also dermatologically tested to ensure skin compatibility and everyday comfort across different skin types, including sensitive skin.

As with any new skincare product, patch testing is always recommended for highly reactive skin.

Does Core contain fragrance?

Core may contain a very mild masking scent from the formulation ingredients, designed to improve the overall application experience without overwhelming the skin.

The formula is created with skin comfort in mind and is intended to remain suitable for sensitive and acne-prone skin types.

Is Core safe during pregnancy and breastfeeding?

Yes, Core can generally be used safely during pregnancy and breastfeeding. It does not contain retinoids or ingredients commonly avoided during these periods.

The formula focuses on hydration, barrier support and gentle skin balancing using clinically accepted ingredient levels suitable for everyday use.

However, if you have specific medical concerns or heightened sensitivity during pregnancy, it’s always best to consult your doctor before introducing new skincare products.

Can I combine Core with other active ingredients?

Yes. Core layers well with most active ingredients and works especially well as a supportive hydrating serum alongside stronger treatments.

Its blend of humectants, niacinamide, peptides and soothing ingredients helps support the skin barrier and maintain hydration while using exfoliating acids, retinoids or acne-focused actives.

Because Core already contains niacinamide and vitamin C derivatives, avoid excessively layering multiple high-strength versions of the same ingredients if your skin is very sensitive. As always, patch testing is recommended when combining new actives.
