UNDER ARM SERUM
Most users notice visibly brighter and more even underarm skin within 2–3 weeks of consistent, twice-daily use.
Yes, 92% of users reported reduced odour and improved all-day freshness starting from the first week of regular use.
Absolutely. The serum is a clinically tested, dermatologist-approved, and gentle formula designed to be safe for all skin types, including sensitive skin.
Ensure your underarm area is clean and dry. Apply 2–3 drops to your fingertips, spread gently in circular motions, and let it absorb completely—there is no need to rinse.
It features Glycolic Acid, a gentle AHA exfoliant that removes dead skin cells, helping 83% of users achieve a smoother skin texture with reduced dark patches after 4 weeks.
HAIR MASK
Leave the mask on for 10–15 minutes to allow the keratin to deeply penetrate each strand.
It is best used 1–2 times per week.
Yes, it smooths the cuticle, enhances manageability, and maintains natural curls while eliminating frizz.
No, the formula is both sulfate-free and paraben-free.
It restores strength and elasticity, adds visible shine, and leaves hair silky smooth.
HAIR INHIBITOR SERUM
It contains 2% Dihydromyricetin, a hero active that directly targets the hair follicles to slow down future hair regrowth and drastically reduce hair density over time.
For maximum absorption, spray it on clean skin immediately after hair removal (waxing, shaving, or threading). Do not rinse it off—it is a leave-on treatment.
Apply it twice daily consistently. You will start noticing visible results within 3 months.
Yes. It features 0.1% Centella Asiatica Extract alongside Glycerin to instantly calm redness, soothe post-removal irritation, and protect every skin type.
It is an inhibitor, meaning it significantly slows down regrowth and makes returning hair much finer, softer, and lighter in texture. It does not permanently eliminate hair like laser treatments.
THE CORE LAB SHAMPOO
Yes, it features a gentle, sulfate-free, and paraben-free formula designed specifically for regular, daily use.
Users notice significantly reduced frizz and flyaways after just 1–2 washes. For softer, shinier, and more manageable hair, you can expect results after 3–5 washes.
Yes, the Hydrolyzed Keratin works to repair and fortify each strand from within, which reduces breakage and restores resilience. In fact, 90% of users felt their hair was stronger with noticeably less breakage after 2 weeks of consistent use.
No, it uses Coco Betaine, a gentle plant-derived cleanser that removes impurities without stripping your hair of its natural moisture.
Thoroughly wet your hair, apply a pump to your palm, and massage from roots to ends to create a rich lather, then rinse completely. For the best results, follow up with Frizz Fix Conditioner.
SELF CARE BUNDLE
Apply the Underarm Brightening Serum on clean, dry skin daily to treat hyperpigmentation. For the Hair Inhibitor Serum, apply it immediately after hair removal (waxing, epilating, or threading) and continue using it daily to slow down and thin out new hair regrowth from the roots.
No, it is a targeted treatment formula. It does not remove existing hair on contact. Instead, you remove hair using your preferred method first, and then apply the serum. It absorbs into the empty hair follicles to significantly delay growth cycles and reduce the thickness of future hair strands.
Yes, while optimized for sensitive underarm skin, this formula is highly effective at clearing dark shadows, rough textures, and hyperpigmentation on other stubborn areas like elbows, knees, and intimate body folds.
Absolutely. Both serums are paraben-free, alcohol-free, and formulated with gentle, skin-loving actives that actively soothe razor bumps and prevent skin irritation while target-treating darkness and hair density.
Most users see a noticeable softening of skin texture and an even-toned brightening effect within 2 to 3 weeks. Visible reduction in hair thickness and significantly longer gaps between hair removal sessions typically become clearly apparent after 3 to 4 weeks of consistent daily usage.
HAIR GROWTH BUNDLE
Yes, it is formulated to work safely and effectively across all hair structures, including straight, wavy, and natural curls.
Use the shampoo every time you wash your hair (2–3 times a week). Follow up with the hair mask 1–2 times per week as an intensive treatment instead of a regular conditioner.
Absolutely. The bundle is specifically curated to rebuild elasticity and target structural weakness, which directly reduces hair fall caused by breakage and splitting.
No, both the shampoo and the hair mask are completely sulfate-free and paraben-free, ensuring a gentle cleanse and deep repair without stripping away your hair's essential moisture.
Most users notice softer, more manageable hair after just 1–2 washes, with a visible reduction in frizz, fewer knots, and significantly stronger strands within 2 weeks of consistent use.
