Dispense a few drops into your palm and apply directly to skin, or mix a few drops into your serum or moisturizer. **Q: Are there any products or ingredients C15 Super Booster should not be used with?** A: Avoid using with copper peptides, as they can oxidize vitamin C, making it less effective on skin. Otherwise, it's safe to use C15 along with ingredients like retinol, niacinamide, and AHA or BHA. **Q: My C15 Super Booster has changed color. Is it still okay to use?** A: Yes. The color can range from a clear to pale peach, even amber. This variation is normal and doesn’t affect its effectiveness. It may also darken after opening due to air & light exposure. **Q: Is the C15 Super Booster fragrance-free?** A: Yes, though you may notice a mild, naturally occurring scent due to the product's ingredients. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fresh batch, arrived in perfect condition! *by on Reviewed in the United States September 12, 2026* I was honestly nervous to order this online because pure Vitamin C oxidizes so easily if it sits on a shelf too long. Fortunately, it arrived securely packaged and completely fresh—the serum is a very light, pale yellow, exactly as it should be. Relieved to know I received a fresh bottle. Definitely recommend! ### ⭐⭐⭐⭐⭐ So far, so good *by on Reviewed in the United States June 27, 2026* Kylie skin vitamin C serum is my favorite, but it is not available right now, so I took a stab at this product since AI told me it was good! So far, I have no issues. It is not creamy and silky like Kylie skin vitamin C. It is more of a clear gel type of texture and it's slightly sticky but not bad at all. I like it, and I think it is having a brightening effect after only a couple of weeks. ### ⭐⭐⭐⭐⭐ My favorite Vit C serum *by on Reviewed in the United States October 14, 2024* Definitely recommend! I've been using this product for maybe 2 years and it's done wonders for my skin. I had a different vitamin C serum before this and this one is by far my favorite. (After adding a gentle retinol into the mix it's even better.) The one thing I will say is that it's basically like water so I usually hold a hand up to my face and rub/dab it in as I go so it doesn't run all down my face. It doesn't bother me though since it actually makes it easier to apply all over the face with very few drops. I would say a bottle lasts me anywhere between 2-3 months.I see some reviews talk about issues with packaging and spills but I've personally never had an issue with any of that so, it might depend on location or how far the package is being sent. And for anyone concerned about the product being different colors when you order a new replacement, that's just how this product works! Visit Paula's Choice website or google about the product. There's actually a variation of different colors this product can be and still be safe to use. Vitamin C is finicky like that.Another warning is be careful what else you mix this with and how you layer it with other products. Looking at all the reviews I am curious how many novice skincare folks are buying this product not realizing that vitamin C is an acid. If you don't know what you're doing then you might end up seriously damaging your skin's acid mantle which can causing irritation, burning and/or breakouts. Most of what I'm seeing in the photos looks like that's what happened too so, proceed with caution if you aren't familiar with how to mix skincare products or have especially sensitive skin. And if you use physical exfoliants (which, really no one should be but that's a separate topic) then definitely do not apply this for at least 24 hours. (Again, it's an acid. The pH is 3.1–3.5 according to their website and most retinol's are around 5-6 pH levels.)♡ ## Frequently Bought Together - Paula's Choice BOOST C15 Super Booster, 15% Vitamin C with Vitamin E & Ferulic Acid, Skin Brightening Serum, 0.67 Ounces - Paula's Choice SKIN PERFECTING 2% BHA Liquid Salicylic Acid Exfoliant-Facial Exfoliant for Enlarged Pores, Wrinkles & Fine Lines and Suitable for Blackhead-Prone Skin - Paula's Choice CLINICAL 1% Retinol Treatment Cream with Peptides, Vitamin C & Licorice Extract, Anti-Aging & Wrinkles --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/1087382-boost-c15-super-booster-15-vitamin-c-face-serum](https://www.desertcart.pt/products/1087382-boost-c15-super-booster-15-vitamin-c-face-serum) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-07*
