Debbie, this much vitamin C does work wonders for the skin. But if it stings badly, use something with less vitamin C and work your way up gradually. You won’t get the same results as your friend if your skin isn’t ready for it.

Sofie, so glad to hear my blog is helping you! Yes, vitamin C goes bad in silicones too BUT not as quickly. It should last you a few good months in this vehicle. Use it in the morning to boost the effectiveness of your sunscreen and the retinol at night.

Keep in mind that both products are very strong so start small. Use them both 3 times a week, vit C in the morning and retinol at night. If all goes well, you can increase frequency.

Will the vitamin c in Indeed Labs Vitamin C24 go bad, when it is in silicone, or will it last like any other cream? I am thinking of getting it along with Indeed Labs Retinol Reface Retinol Skin Resurfacer and then use them at night 2-3 times a week under my The Ordinary rosehip seed oil and finishing of with a moisturizer (I get pretty dry skin, especially when the summer ends). Would you recommend using them together, and if yes, in what order? Or do you think it is better to use them on alternate evenings? I am a beginner with retinol, and I have only used a little vitamin c in the past. Should I use one of them in the morning instead? Thank you so much for an amazing blog!! Your work has helped me so much with my skin concerns 🙂

Sabeen, only a little. I’ve written more about this here: http://www.beautifulwithbrains.com/do-silicones-prevent-other-ingredients-from-sinking-into-the-skin/
