    Hello DEWEY skin! I absolutely love, and highly recommend Lekko’s Illuminating C Serum. This amazing product not only tightens my skin, it gives it a youthful supple glow. I have tried many face serums, this one is by far the best. I love my C Serum! ?

    This is an incredible Vitamin C serum, and I have tried many previously. I love using this product in the morning after I wash my face and before applying makeup. My skin looks brighter and textureless, and I really need far less makeup after this.

    • Danielle

      Thank you Yelena! Happy to hear you love our products!

    This is honestly the best serum I have ever used, and I’ve tried dozens of serums. I noticed a difference in my skin pretty quickly, but it has been over 6 months now since I started using it and it has seriously transformed my skin! It’s so much brighter and I always feel like I’m glowing, I will never stop using this product.❤️

    This is my favorite Lekko product! A little goes a long way! The glow you get is amazing! It is light weight and absorbs quickly but boy is it effective! Would give this 10 stars!

  5. Dana

    I absolutely just love this vitamin C serum. I’ve used vitamin c serum before but never had the results I have with this serum. My skin is bright, smooth and it looks like I have less lines in my face. This serum is awesome. I would Highly recommend this vitamin c serum.

    This is the only serum I will use under my makeup. It absorbs so perfectly and doesn’t make my skin feel oily. I see a huge amount of improvement in the overall appearance of my skin. Love this stuff!

    Vitamin C Illuminating Antioxidant serum-

    The number one seller, and I can see why! The actives in this product are outstanding. Percentages and purity to truly be effective! With just a few uses, my skin was more even and radiant and feels alive! I feel that I am really doing something to slow down the aging process and improve my skin with the use of this product.

    Love the vitamin c serum! It has brightened my skin and gives a nice glow and fresh look when I apply it before my makeup. It has evened my skin and made my pores less visible. This is one of my favorite products!

    This is one of the best Vitamin C serum I’ve ever come across. Tried and true, it surely brightens up my complexion and help my skin look healthier and younger. I highly recommend this serum for anyone who’s looking for natural glow from within!

      Thank you for the excellent review!

  11. Patricia Griffith

    Hi LEKKO, I just wanted to thank you for your amazing product. I have been using the vitamin C for about a year and my skin is just glowing and soft. The first little bottle lasted over 7 months for me and I use it religiously, every day, and some times I have to apply it even twice because of my workout schedule. The value of this product is fantastic for the benefits it delivers! Thank you so much LEKKO!!

    • Danielle

      Thank you for the continued support and lovely review!

  12. Emily (verified owner)

    This is my favorite Vitamin C product (I’ve tried many)! It gives you the glow you desire without the stickiness or poor smell when applied. It is the perfect part of my daily morning skin routine with a great impact. As a first time mom with the sleepless nights with a newborn, I give this product the credit for maintaining clear, even toned and textured skin. Bonus- a little goes a long way and the product lasts for much longer than other products on the market.

    • Danielle

      Thank you for your kind review Emily! We appreciate this wonderful feedback!

    I’ve bought every skin regime possible.. from the very high end to the low end. These products are the best I’ve ever tried…the results and the feel of your skin are seriously almost instant. I’d unequivocally recommend to anyone to try this line…if it has any credibility it was a plastic surgeon’s office that got me hooked on these!

  14. Kiara D.

    My skin looks SO awake and bright when I use this Vitamin C serum. It gives me a gorgeous dewy, textureless complexion! I’ve tried a few other Vitamin C serums and this one is definitely the most potent and effective one I’ve used. Hello GLOWY skin!

  15. Jenn

    These products are a must have for any girl! My skin has never been glowing or dewy. These products have truly changed that for me and I feel so confident to wear no makeup and reveal my true skin💕
    Thank you so much Danielle for taking the time to create truly beautiful products that allow girls to invest in their skin and get real results🥰
    A very grateful girl 😘

  16. Seppy

    The best ! I love the texture and the way it spreads on my skin !

  17. Matthew

    I absolutely adore this product! It has been a major staple of my skin care regiment for quite a while now, and I still receive many compliments of my skin texture and evenness. Something I am never tired of hearing! Thank you, Danielle, for always being an amazing provider and introducing me to this game changer!

  18. Shadiaya Haynes

    I recently started using Lekko products for my skin and I must say they are amazing. My skin has been glowing through the roof! I have to give this product personally a 100/10 because it is simply that good! Don’t hesitate to buy… you won’t regret it!!!

  19. Joelle (verified owner)

    I started using Lekko products 9 moths ago and I absolutely love them. My skin has a glow that even my teenage boys noticed and said ” Wow, your face is glowing.” I often receive compliments on my skin since using these products, which is always welcome and I know a direct result of these amazing products. The Exfoliating cleanser, Vitamin C serum ad Lock it in moisturizer are a must have staple for anyone. I can’t say enough wonderful things about all of these products. They are truly making a difference in the texture and appearance of my skin. Thank you Danielle for creating such wonderful products that truly make my skin glow. If you are thinking of trying these products, just do it, you will not regret.

  20. Barb

    I absolutely LOVE this serum! There are other vitamin C serums I’ve tried that left a sticky residue, but this formula is so light and pleasant on my skin. I started using it two months ago and it has helped even out my skin, and made it smooth again. I will continue to use this product forever!
