Reduces hyperpigmentation

Skin feels hydrated and dewy

How to use

How To Use

After cleansing, dispense two pumps into your palm and apply all over your face. Follow with our Overnight Moisture Revitalizing Cream to nourish and protect.

Jillian’s Tip

Make this brilliant serum a part of your evening routine, when your skin isn’t exposed to the skin-damaging free radicals you will encounter from the sun and environmental pollution. 

If you use a retinol or AHA product at night, apply your Vitamin C serum in the morning or test out layering it with your retinol or AHA products slowly to avoid irritation.


Active Ingredients

3-Glyceryl Ascorbate - A stable form of Vitamin C that is also gentle on the skin. Studies have also shown that this ingredient may have antibacterial properties and has been proven to help reduce breakouts.

Magnesium Ascorbyl Phosphate - A stable form of Vitamin C that is prized for its ability to reduce the appearance of hyperpigmentation, fend off free radicals, and increase hydration.

Niacinamide - This water-soluble form of Vitamin B3 assists with barrier repair. It is a real asset to anyone with acne prone skin, helping to regulate sebum production and reduce the appearance of large pores.

Licorice Root Extract - A superior antioxidant and anti-inflammatory which also assists in inhibiting tyrosinase. Its superb brightening properties are said to be on par with controversial ingredient hydroquinone, but this miraculous botanical is far, far safer and gentler.

Hyaluronic Acid - A natural sugar molecule found in skin, this famed humectant ingredient helps to bind water to collagen making skin moisturized, plumper, and firmer.

How will this benefit my skin?

Get the "Vitamin C Glow" you want with this Illuminating Serum with Vitamin C. Rich and dewy on the skin, with actives that will even out your skin tone, brighten dark spots, and encourage collagen renewal.

Illuminating Serum with Vitamin C includes an incredible brightening botanical - Licorice Root Extract - one of the most potent and effective ingredients for helping to reduce the appearance of unwanted hyperpigmentation.

This serum doubles the effort of brightening skin tone with two ultra-stable forms of Vitamin C.

One form has a glycerin-based composition, enhancing skin hydration while offering a distinctive, delightful sensory experience.

Packed with antioxidants, it not only brightens the skin but also boasts a rich, hydrating serum formula. The luxurious emulsified formula glides on the skin, providing additional moisture from the liquid crystal emulsifier structure.

Vitamin C stands as the pinnacle in skincare for its ability to amplify skin radiance and luminosity.

This serum tackles dark spots and patches resulting from sun damage, melasma, or breakouts with unmatched efficacy.

It’s the ultimate solution to restore skin vitality and brightness, setting a new standard in skincare excellence.

Can I layer this with other products?

You can confidently layer the Illuminating Serum with Vitamin C with all of the Acta Beauty products.

If you're using a retinol product, be sure to spot test this serum after you've applied retinol to ensure irritation doesn't occur.

Bakuchiol, found in Acta's Resurfacing Serum and Eye Cream, is a retinol alternative, but is not related to retinol, so you can layer with these products.

Will this work for sensitive skin?

This formula is ideal for all skin types, and even highly sensitive skin should be able to tolerate it.

Do I use this day, night, or both?

We recommend using Vitamin C at night, as long as you're not also layering it with a retinol product.

Why use it at night? Vitamin C can cause sensitivity in the sun and can also degrade faster when it comes in contact with UV rays. By including it in your nighttime routine, you'll be sure to avoid any potential sun exposure issues.

Kathy A Tolich

After living in California for 50 years, my skin has seen a lot of sunshine. There was damage left on my face from too many years of not wearing the proper sunscreen. After using the Illuminating Serum with Vitamin C, my skin is radiant! The dark patches are now almost nonexistent. My skin has been renewed and is healthier than I've ever seen it. I'll be turning 60 next month and no one would guess my age by looking at my face. Thank you, ACTA, for giving my skin new life!

Kathy, that's amazing! I'm so happy your skin is looking radiant!
