A person can apply serums or other active ingredients to their skin before applying Vaseline as a moisturizer.
Yes, you can use Vaseline (petroleum jelly) as a moisturizer after applying a retinol serum. Retinol can be drying and irritating to the skin, especially when you first start using it. Applying Vaseline can help lock in moisture and create a barrier to protect your skin.
Beta Hydroxy Acids
So that salicylic acid of yours should not be mixed with your vitamin C serum. It won't be able to help you with discoloration, collagen production, or protect you from UV rays. Additionally, combining the two can cause irritation and dryness.
Vitamin C serum is typically applied before moisturizer. After cleansing your face, you would apply the serum, allow it to absorb, and then follow with your moisturizer. This sequence allows the serum to come into direct contact with your skin and be absorbed more effectively.
In other cases, mixing can destabilize or cancel out the benefits of the antioxidant. Here are some ingredients to never mix with vitamin C: Alpha Hydroxy Acids (AHAs): Lactic Acid, Malic Acid, Glycolic Acid, Citric Acid, Tartaric Acid.
Vitamin C is effectively an acid (it's sometimes known as ascorbic acid), so layering it with AHAs and BHAs like glycolic, salicylic, and lactic acids is a big no-no.
Evening routine
In the morning I tend to use vitamin C and hyaluronic acid and in the evening the retinoid serum at the moment, but again, just cleansing, serum, and then oil and at the moment like I said I'm testing this barrier repair overnight cream as well in the process.
Vitamin C serums are notoriously sensitive to light, air, and heat. Exposure to these elements can cause the serum to degrade, leading to reduced effectiveness. Unfortunately, this is a mistake that many people overlook.
The American Academy of Dermatology recommends petroleum jelly for keeping a wound moist and to help prevent it from drying out and forming a scab, because they take longer to heal. This will also help prevent a scar from getting too large, deep or itchy.
But hold on, can you put Vaseline® products on your face? The frequently asked question has a simple answer: Yes! Vaseline® products, including Vaseline® Original Healing Jelly, are absolutely safe for your skin. The Vaseline® Jelly is non-comedogenic, which means it does not block or clog your pores.
Mic drop 🎤 petroleum jelly (such as vaseline or aquaphor) over retinol can lead to increased side effects from the retinol (irritation!)
For even-looking skin, pair Vitamin C derivatives with Glycolic Acid. For smoother-looking skin, pair Retinaldehyde and Hyaluronic Acid. For clearer-looking skin, pair Salicylic Acid and Niacinamide 10% + Zinc 1%. For hydrated skin, pair Hyaluronic Acid and Niacinamide.
You'll layer whichever occlusive you use, such as petroleum jelly, over thinner skin care ingredients, including serums and other moisturizers. This allows products like toners, serums and lotions to penetrate the skin before you apply a thick occlusive.
However, if you are prone to sensitivity, you might want to skip your more active serums and treatments (those with vitamin C, niacinamide and retinoids) on nights you slug. Slugging traps these ingredients within, which is usually great, but can cause some irritation on sensitive skin.
Dermatologists recommend you apply vitamin C serum before you apply moisturiser and sunscreen.
4) Why does my skin look darker after using Vitamin C? If you are applying Vitamin C without sunscreen, it is likely that the Vitamin C degrades into Erythrulose, which is an ingredient you will find in many self-tanners. So please make sure you apply sunscreen always after applying Vitamin C.
Vitamin C + Niacinamide
However, when you combine niacinamide with Vitamin C, they'll cancel each other out chemically, making both formulas ineffective on your skin. Niacinamide takes out all the good properties of Vitamin C and makes it into a substance that can cause redness and trigger breakouts.
Possible interactions include: Aluminum. Taking vitamin C can increase your absorption of aluminum from medications containing aluminum, such as phosphate binders. This can be harmful for people with kidney problems.
Skincare ingredients not to mix with vitamin C
Vitamin C, AHAs (glycolic acid), and BHAs (salicylic acid) are acidic in nature. Layering them together can lower the skin's pH, making it more acidic. When skin pH goes off balance, it becomes a recipe for skin irritation, redness, and peeling.
Vitamin C should not be mixed with acids, which includes all AHAs and BHAs. Vitamin C plays a key role in strengthening the outer layer of our skin barrier, but when combined with an acid, it can enhance the potency of your vitamin C and cause severe irritation [5].
Vitamin C serum takes approximately one to two minutes to properly absorb into your skin. Allowing this time to pass before you apply additional layers or skincare products will help ensure you're getting maximum benefits from your serum.
Nighttime: Layer Vitamin C Serum with Night Cream
Layer our Vitamin C Serum with a nourishing night cream. Since Vitamin C can be an unstable ingredient, avoid using other AHA, BHA or Retinol products to prevent skin irritation or destabilization of the Vitamin C.
