• 15% Vitamin C + EGF Serum can be used in your AM & PM skincare routine. However, if only using once per day we recommend AM (and using an SPF) to get the most out of its antioxidant properties!
• After cleansing and hydrating with Hyaluronic Acid Serum, apply a pea-sized amount of 15% Vitamin C + EGF Serum to face and neck and follow with your preferred moisturiser.
• Apply SPF as the last step in your AM skincare routine.
• INKEY Tip;
  • When layering treatments, we suggest working from thinnest to thickest consistency. Waiting a minute or so between applying each treatment will also help to avoid pilling.
  • Avoid using Vitamin C at the same time as Retinol, Alpha Hydroxy Acid products (Glycolic Acid, Lactic Acid, AHA, Mandelic Acid or Apple Cider Vinegar) or BHAs (Beta Hydroxy Acid or C-50 Blemish Treatment). Use Vitamin C in the morning and Retinol OR AHAs/BHAs/PHAs in the evening.

When adding new products to your skincare routine, we always recommend patch testing. Learn more here.

We advise that prior to exposure to sun you use a broad spectrum SPF, immediately and up to 7 days after.

Store in a cool dry place out of sunlight. Avoid direct contact with eyes. External use only. Keep out of reach of children.

HOW OFTEN CAN I USE 15% VITAMIN C + EGF SERUM? We recommend using this once per day, during your AM routine to take an advantage of full antioxidant properties. We recommend using a broad spectrum SPF in your AM routine if you are using Vitamin C.

CAN I USE VITAMIN C AT NIGHT? Yes you can! It is most beneficial during the day due to the antioxidant properties but you can certainly use it in the PM too if you prefer

CAN I LAYER 15% VITAMIN C + EGF SERUM WITH OTHER INGREDIENTS? We do not recommend layering this with exfoliating acids (Alpha Hydroxy Acid, Glycolic Acid, Lactic Acid, Mandelic Acid or Apple Cider Vinegar), BHAs (Beta Hydroxy Acid or C-50 Blemish Treatment) and Retinols. This is because mixing those ingredients can lead to irritation, so we recommend alternating them. We suggest using Vitamin C in the morning and Retinol OR AHAs in the evening. What products should I not layer together? >
CAN I LAYER VITAMIN C AND NIACINAMIDE? You can safely layer Niacinamide alongside our 15% Vitamin C + EGF serum because it uses Vitamin C derivative, Ascorbyl Glucoside. We do not, however, recommend mixing pure L-Ascorbic Acid with Niacinamide as this could sensitize your skin and be potentially irritating. 
DO I NEED TO WAIT AFTER APPLYING 15% VITAMIN C + EGF SERUM? If you would like to use other skin care products on top, wait around 10 minutes before using them. This gives the skin cells enough time to respond to the EGF and it won't affect the cell rejuvenation process.
I HAVE SENSITIVE SKIN, CAN I USE THIS? Yes our 15% Vitamin C is a gentler formula but we still encourage patch testing. Learn more about patch testing >

 WHAT IS EGF? Epitensive™ is a plant-derived Epidermal Growth Factor system to support natural elasticity and skin health. It is a signal peptide, stimulating skin cells to regenerate and refresh the dermis and enable rejuvenated skin.
WHAT IS THE % OF EGF? 15% Vitamin C + EGF Serum contains 1% plant EGF system.
WHAT IS THE PH LEVEL OF THIS PRODUCT? PH LEVEL: 6.8–7.2
WHAT’S THE DIFFERENCE BETWEEN VITAMIN C AND EGF? Vitamin C and EGF Serum can both help to brighten the skin, but work in different ways. Vitamin C is an antioxidant, that not only helps protect against free radical damage resulting in younger skin, but also stimulates multiple skin cell activity including collagen synthesis and stops enzymes that create melanin resulting in refreshed and brighter skin. EGF is a signal peptide, stimulating skin cells to regenerate and refresh the dermis and enable rejuvenated, youthful skin. By pairing both of these ingredients together, our 15% Vitamin C and EGF Serum gives your skin a double hit of cellular activity for brighter, younger skin.
HOW DOES THIS DIFFER FROM YOUR VITAMIN C 30% SERUM? Our 30% Vitamin C is formulated with pure L-Ascorbic Acid in a waterless formula and is recommended for experienced Vitamin C users. Our 15% Vitamin C is much gentler product more suited for beginners and uses a Vitamin C derivative, Ascorbyl Glucoside, with the addition of EGF. 

WHAT ELSE CAN I USE TO BRIGHTEN MY SKIN? We suggest using Fulvic Acid Cleanser & Symbright Moisturiser to boost your brightening skincare routine

HOW LONG WILL IT TAKE TO SEE RESULTS?  Products can take up to six weeks to show full results, due to the time it takes for your skin cells to turnover and the results of any products to reach the surface. Consistency is key, so apply regularly even if you’re not seeing the effects straight away. It can be very tempting to increase use of some products to try and see quicker results, don't overdo it though. More is not necessarily more, and overuse can cause irritation and sensitivity. 

IS THIS PRODUCT VEGAN? Yes! This product contains no animal derivatives and is now certified by The Vegan Society.
IS THIS SAFE FOR THOSE WHO ARE PREGNANT OR BREASTFEEDING? Yes! You can safely use 15% Vitamin C + EGF Serum when pregnant or breastfeeding. Your guide to pregnancy safe skincare >
CAN I USE THIS WITH PRESCRIPTION MEDICATION?  We would suggest you consult with your doctor to be sure.
