Ever since I was a child, I loved to make people feel and look beautiful.

What Ingredients Should Not Be Used Together

As we know by now, I’m a ‘go big or go home’ type of gal! So when it comes to skincare, I often use & write about the products that will get you the most bang for your buck! But often times, I want a quick fix (like I would say most of us) and that’s when trouble can arise. This is a perfect example! I have a vitamin C product from my doctor and I also use Liquid Lightning Vitamin C that’s an over the counter product. So I noticed that some of my dark spots were popping up when I was on my menstrual cycle (it’s a real thing, my dermatologist said I was observant! YASS!!), so I decided to double up on my vitamin C – now vitamin C is often used as an exfoliant, so you can imagine my face the day after… it was peeling and dry! That’s when I screwed up in the ‘go big or go home’ mentality! I should have been more patient and not mixed two vitamin C products together.

This story brings me to the point of this whole blog is that there are just some products that you shouldn’t mix together! And if you do, you may find that your skin is irritated, dry, flaky, overly sensitive, yada yada – like mine was the other day. So while it’s important we stick to the regimes that work, it’s also important that we’re careful to choose when to use the ingredients and when not to! And not only that, but I had a skincare provider tell me one time that one of my vitamin C products may cancel out the effectiveness of a SkinMedica product that was also vitamin C based, so she encouraged me to wait 5 minutes before applying. (I must have an issues with vitamin C lololol!) It’s not just that you can get irritation, but you can also cause your products not to even work!

Vitamin C & Vitamin C – Like I mentioned earlier! By mixing vitamin C products together, you can have one of two effects… You can either get extremely dry and irritated skin, or you can actually cause a neutralizing effect that will cause both products to not have any benefit to your skin! So in this case, stick with one vitamin C product that you trust & if you’ve got a stronger vitamin C product that was given to you by your doctor that you’re to use less frequently, make sure not to use your over the counter product on those nights.

Vitamin C & Retinol (Vitamin A) – Both act as exfoliating agents, so if you use a strong vitamin C with a retinoid, you will find that you’re getting dry & flaky skin! I always use my doctor prescribed vitamin C product on Sunday nights & I know that I’m not to use the retinoid at that time. I do however use my over the counter vitamin C with my retinol, but I either wait a while between applications or use the vitamin C in the morning & the retinoid at night! Just depending on how I feel my skin is reacting.

There are new technologies where retinoids & vitamin C ingredients are in the same product, but they are able to have the retinoid function in a time-released fashion! Allowing the vitamin C to penetrate quickly! 

Vitamin C and AHA’s & BHA’s (i.e. Glycolic acid)- These guys are incredibly effective when used separately! In fact, if you use them together, you will find that they have the same neutralizing effect as mixing two vitamin C’s together.   While both help to brighten the skin and even out the skin, vitamin C contains more antioxidants to protect against aging. AHAs are best to treat fine lines, acne, and hyperpigmentation. Consider using your vitamin C in the morning (with a lot of sunscreen) & using a glycolic acid peel before bed time!

Vitamin C & Niacinamide – Vitamin C is really finicky right!? When used together, niacinamide can turn vitamin C yellow. That’s when you know that vitamin C is no longer jammed packed with awesomeness. It means its anti-aging properties have gone bye, bye! So while it’s not always the case, you may want to think twice before mixing the two!

Retinol & Benzoyl Peroxide  We had a Cheeky come to us for some acne concerns on her forehead! She was using an over the counter benzoyl peroxide treatment, but also wanted to use a good retinol in her evening routine. But we learned that she was using both the zit cream and the retinol at night! This was probably irritating her skin! So I suggested she use the acne treatment in the morning (with plenty of sunscreen) and the retinol product at night. She noticed a world of difference just by changing up her routine!

Benzoyl Peroxide & Hydroquinone – With this ingredient mix — benzoyl peroxide is most effective for acne, while hydroquinone is an amazing skin lightening agent — you’re headed straight for some serious skin peeling & irritation.

Retinoids & Sunscreen – We should most certainly be using our sunscreen in the daytime & saving our retinoids for when we sleep! Retinoids can make your skin very sensitive to the sunlight & UV rays, so if you use your retinoid product in the morning, expect to get some sun damage, especially if you aren’t using sunscreen! I use a retinoid about 5-6 times a week & wear my sunscreen daily and I think that regime works best for me and my skin type.

Cleansing Oils & Serums/Ampoules – While cleansing oils are amazing for taking off makeup and lots of dirt, grime and pollution, it can hinder the effects of products used afterwards, especially products with similar consistencies like serums! And we all know that serums are usually uber potent & expensive, so we surely don’t want that. Because cleansing oil is thick in texture, it can often inhibit other skincare products from really saturating into our skin. I typically use cleansing oils just in my eye area rather than over my whole face to allow all my skincare products to really sink in! Or you can use a cleansing oil and then use your cleansing tool like a Clarisonic & use a regular old face wash to ‘wash’ off some of the thick oils. (I do this when I’ve got heavy makeup on and I’ve used my oil all over)

Have an ingredient or two that is concerning you!? We’d be happy to talk to you individually about which ingredients will work best for your skin! Let us know in the comment’s section about an ingredient or two that’s not on the list, that you know not to mix.
