IYASA 5% Vitamin C Serum - Potent Anti-Aging & Skin Brightening Formula with Natural Scent - Boost Collagen, Hydrate & Plump Skin, Dark Spot Reduction, Anti-Wrinkle Facial Serum 30ml

  • [Why Does This Product Have a Distinct Smell?] Our formula contains 5% Vitamin C, a concentration that is both effective and potent. It's normal for products with this level of Vitamin C to have a characteristic scent, which is a natural result of the active ingredients. This scent is a sign of the product’s efficacy and will fade shortly after application, ensuring you still enjoy the full benefits without any lingering smell.
  • [ANTI AGING FORMULA]: Purposefully balanced blend with Vitamin C, botanical Hyaluronic Acid, Vitamin E, Aloe Vera, Jojoba Oil, and MSM to help brighten, calm, and protect the skin.
  • [BETTER FORM OF VITAMIN C]: Highly stable, Sodium Ascorbyl Phosphate maintains potency longer with less skin stinging than other commonly used forms of Vitamin C.
  • [SKIN FRIENDLY, GENTLE SKIN CARE]: Fragrance-free nourishment with vital nutrients, antioxidants, and botanical actives to improve skin wellness. Vegan, cruelty-free formula without parabens or harmful chemicals.
  • [THE TRUSKIN DIFFERENCE]: If this product isn't a fit for your skin, we're here for you. Each balanced blend of key antioxidants, super-nutrients, and botanical actives enhances efficacy and delivers skin-friendly benefits, without additives or fragrances. The expiration date is printed on the barcode sticker on the packaging.
  • 𝗧𝗨𝗥𝗡 𝗕𝗔𝗖𝗞 𝗧𝗛𝗘 𝗖𝗟𝗢𝗖𝗞 𝗢𝗡 𝗔𝗚𝗜𝗡𝗚: Our vitamin C serum uses 3-O Ethyl Ascorbic Acid to quickly boost your skin’s glow – unlike most serums, which feature weaker derivatives.
