Revitalise C20 serum is a unique synergy solution that combines the best of selected potent anti-oxidant ingredients for exceptional results. L-ascorbic acid combined with vitamin e and ferulic is a potent combination resulting in upto 8x more antioxidant capacity than l-ascorbic acid alone. At 20% this is the highest stabilized concentration of l-ascorbic acid available.

This serum is formulated with hyaluronic acid as a base making it very light weight.

Benefits of l-ascorbic acid (most active form of vitamin c) are well described in medical literature to be:

  • Free Radical Neutralising (Antioxidant neutralises Oxidants) thereby reducing damage to skin structures (collagen, elastin, hyaluronic acid etc)
  • Decreases irregular melanin production (decreasing dull & uneven tone skin)
  • Collagen synthesis
  • Anti-inflammatory (acne type conditions)
  • Enhances sun protection
  • Use in combination with Stimulate RA (retinal .1%) or Renewal cream in the evening for completion of Vitamin C & A regime boosting even skin radiance and smooth surface texture.
  • In the morning apply SPF to increase sun protection; only if going to be outside (SPF of no benefit indoors away from a window; unnecessary chemical application should be avoided). SPF usually lasts 3-4 hours so an application in the morning may have little benefit at lunch break.


Dispense 4-5 drops of this serum on your palm and then evenly massage it on your complete face and neck. Use it as a first product after cleansing the face and allow it to absorb before the use of any other product.

  • For external use only
  • Discontinue use if persisting redness or irritation (after 7-10 days). Initially l-ascorbic acid stings and irritates a little as well as causing mild dryness. Allow skin to gradually condition to it by increasing dose over a few weeks

Frequently Asked Questions

At Harley Street Formulations, our skincare experts know to make sure that the products are created using research-backed and up-to-date technology.
Ferulic acid prevents and corrects skin damage by fighting free radicals, as well as extending the life and efficiency of vitamin C.
Moreover, by adding Vitamin E to this antioxidant serum, you are providing your skin twice the antioxidant defense it needs to combat free radicals and UV damage.

If you are not ready for Botox yet, try Revitalize C20. The whooping 20% L-ascorbic acid works tremendously well against ageing signs. Vitamin C helps to fight off free radicals that are actually responsible for fine lines and wrinkles.
Harley Street Formulations has introduced this potent formula for every skin type and all ages. This lightweight serum even plumps up your dehydrated skin and brightens a dull one.

The major difference between two best sellers is the concentration of L-ascorbic acid in them. Revitalize C12 contains 12% L-ascorbic acid whereas Revitalize C20 has 20 % L-ascorbic acid which is the highest stabilized concentration of Vitamin C.
Moreover, Revitalize C12 is not blended with any other ingredient and has a pH of 2.5 to 3.0. Revitalize C20 is relatively less acidic with a pH of 4.0-4.5. Moreover, it has ferulic acid as well as Vitamin E.

Most dermatologists and Cosmexperts recommend using Vitamin C serum in day time for a superior protection against sun’s UV rays. However, there is nothing wrong in adding this skin superhero to your bedtime routine.
While you’re sleeping, your body goes through its natural healing process. As you apply Revitalize C20 it will also soak more efficiently into your skin after you’ve cleansed it, so it is equally great to use it at night.

Traditional Vitamin C serums out there contain high pH and hence are more acidic and harsher for sensitive skin.
Therefore, look for an anti-oxidant serum that contains skin-soothing and hydrating ingredients such as Vitamin E or hyaluronic acid to keep signs of inflammation at bay.
Revitalize C20 is a great pick for sensitive skin because its pH is between 4.0 and 4.5. Moreover, HSF has ensured to steer clear from using any fragrance, phthalates, parabens or sulphates while formulating products for your skin.

Take care of your vitamin C serum to protect it from  losing its strength, and it will take care of you!

L-Ascorbic acid is sensitive to light exposure so try to store your bottle in the dark and away

KEEP IT AWAY FROM HEAT from direct exposure to sunlight and air.
Vitamin C can be easily damaged by high temperatures. As a result, severe heat exposure must be avoided as much as possible.

    I love this product. I have been using it for 18m and have seen a huge improvemt to my skin tone. It it’s much brighter and reduced dullness and uneven skin tone. I have also noticed an improvement to my acne. It makes my skin feel beautifully soft.

    This is my number one essential skin product both winter and summer and I apply it every morning after cleansing. It couldn’t be easier to apply and sinks in almost immediately. I’ve tried other Vitamin C serums and keep coming back to this one! It keeps my skin bright and I wouldn’t be without it. I often get compliments on my skin and how youthful I look and I like to think this contributes…
