Resist C15 Super Booster is an innovative, fragrance-free, water-based specialty skin-care product designed to boost the effectiveness of the anti-aging serum or moisturizer you're using. Fortified with 15% pure vitamin C and packaged to protect this delicate ingredient from light and excess air exposure, it works quickly to firm, brighten, fade dark spots from sun damage, and restore a more youthful look to all skin types.

The water-light texture is easy to apply, and only a few drops of this concentrated formula are needed to see results. Along with vitamin C, the product contains antioxidant superstar vitamin E plus ferulic acid for additional environmental defense. Also on hand are skin-plumping sodium hyaluronate and a peptide to assist in skin repair. C15 is suitable for breakout-prone skin (it can help fade marks from past breakouts, too) and may be used daily or as needed, when skin needs a potent anti-aging boost.

  • Light-as-water texture suitable for all skin types.
  • Boosts the effectiveness of any serum or moisturizer.
  • Ongoing use leads to dramatically younger-looking skin.
  • Fortifies and repairs skin with proven antioxidants.
  • Works quickly to brighten and fade dark spots from sun damage.

Disclosure: In addition to reviewing thousands of cosmetic products from hundreds of brands over the past 30 years, Paula also has her own line of products called Paula's Choice. Paula and her team's goal is to help you find the best products possible for your skin whether they are from Paula's Choice or some other product line. Paula's commitment to this is so strong she is the only cosmetics company owner in the world that recommends products other than her own. Paula and the Paula's Choice Research Team formulate our products to meet or exceed the criteria we use to review products from every other brand on this site. We review all products the same way using the same research, objective comments, and praise no matter whose product it is.

Paula's Choice was created in 1995 in response to the many readers who asked Paula to develop her own products. Given Paula's unique overview of the cosmetics industry, 30+ years of research, and earnest desire to help people find the best products for their skin-care needs, creating her own products was a natural extension of her work. Paula's Choice range of products are designed to meet the needs and preferences of just about every skin type and concern imaginable using only proven ingredients substantiated by published research.

Paula's Choice products provide:

  • State-of-the-art formulas based on reliable, published skin-care research

  • Environmentally-friendly products that feature minimalist packaging that ensures product efficacy
  • 100% Customer Satisfaction Guarantee from our world-class Customer Service Team

Paula's Choice products and Paula's work is routinely praised by noted dermatologists and other professionals. New York-based dermatologist Dr. Debra Jaliman stated that "I have a lot of respect for Paula Begoun and the way she thoroughly researches her subject. Her recommendations about cosmetics and skin care are deservedly influential." Eminent Seattle-based dermatologist Dr. Brandith Irwin concurs: "She takes a complex subject and makes it easy to understand!"

    Another Reason to Switch to Paula's Choice
    • This product is another perfect example of the exceedingly high quality of PC's products. I saw results in two days; combined with the concentrated Retinol serum left my skin so smooth it felt like glass! I actually had people ask to touch my face—it glowed and looked 'new'. Sort of hard to explain but if you try it you will see what I mean. But be warned: her stuff will spoil you, no other line comes close in quality, results, & customer service!

    Great price extremely effective
    • I started using this product as an alternative to skinceuticals C E ferulic acid which is AMAZING but very expensive. These two are literally the same. This product helps balance my skin, no mid day oil slick. Its reduces hormonal and all other breakouts significantly as well as improves healing time plus it brightens my skin. Most days i use this to replace my moisturizer entirely. Anyone could use a little of this product in their life!

    Excellent product
    • Absolutely love this product, saw a difference within a few days. I also use prescription strength retina A, along with sunscreen, retinol and make-up from Paula Begoun. It is the best kept secret! I do tell people about it, since I always get many compliments on my skin. Sold high end skin care for a number of years and it could not compare with Paula Begoun products. However, have to say the C serum is most impressive!

    Love this!
    • I'm 49, and since using this at night, in combination with my RESIST Super Antioxidant Serum, my face is softer, more even-toned, and glowing. I'm using much less foundation (event the Resist Anti-Aging Foundation-sorry Paula!) and love the way my skin looks. The serum does have a slight odor -kind of a metallic, or "a wood-smoke" smell, but it's not bad enough to prevent me from continuing to use this nightly. It's a great addition to the RESIST line. Thanks, Paula!
