    Can You Use Vitamin C and Retinol Together? 2 Common Myths Busted!

    They’re two of the most popular anti-aging skincare ingredients available but what happens when you combine them into the same routine? Can you use vitamin C and retinol together? One skincare myth that seems to stick around like a stubborn blemish is the classic tale of two skincare ingredients that just want to love each other but are forced apart due to their differing pH levels. The Romeo and Juliet of skincare if you will. Where for art thou glowing skin? So are vitamin C and retinol star-crossed lovers or sworn enemies?

    Post Inflammatory Erythema: 12 Effective Treatment Options.

    If you have ever had a bad acne break out, you may have noticed that it can sometimes leave marks on your skin. These marks can be either pink/red or brown in color but don’t tend to cause textural irregularities like true acne scars. Those pink/red marks are post inflammatory erythema and they can be tricky to treat! The good news is that they will eventually go away on their own and these 12 treatments can fade them faster!

    Niacinamide and Hyaluronic Acid Together = Super Skin Hydration!

    Layering skincare products often feels more complicated than it should be. Will they cancel each other out? Will you end up destroying your skin barrier? In most cases, as long as you’re not experiencing irritation, you’re fine to keep layering away – but maybe you want to know whether there is any additional benefit to using multiple skincare ingredients? For example, is it worth using niacinamide and hyaluronic acid together?

Your skin is affected by your circadian rhythm, or Your skin is affected by your circadian rhythm, or ‘body clock’, and goes through various changes over a 24-hour period that allow it to repair and protect itself. ⁣
⁣
These changes include variations in: ⁣
🌿Water loss ⁣
🌿Skin cell turnover and renewal ⁣
🌿Blood flow ⁣
🌿Skin temperature ⁣
⁣
Here are 7 ways you can adapt your skincare:⁣
1️⃣Wear sunscreen! It protects your skin from UV radiation which is responsible for up to 90% of skin aging.⁣
2️⃣Use antioxidants alongside sunscreen as they work synergistically with sunscreen to protect your skin against UV radiation. They also protect your skin from the effects of pollution.⁣
3️⃣Use acidic products (e.g. salicylic acid cleanser, ascorbic acid, etc.) in the morning to keep your skin pH at its acidic ideal. Ascorbic acid (vitamin C) is also an excellent antioxidant. Note: salicylic acid has been shown to protect skin from UV radiation (unlike glycolic acid/AHAs) but it is not a replacement for sunscreen).⁣
4️⃣Use oil-controlling products in the AM – ingredients like salicylic acid, niacinamide, and green tea can help reduce oil production and help control midday oiliness. The latter two are also antioxidants which means they help with #2 as well!⁣
5️⃣Use DNA-repairing enzymes (e.g. photolyase found in bacteria and plants) to help your skin undo the damage done during the day.⁣
6️⃣Enhance your elevated rate of skin cell renewal by using retinoids (e.g. retinol) at night.⁣
7️⃣Use heavier moisturizers at night to reduce the amount of water lost from your skin overnight. Dry skin may benefit from an occlusive moisturizer to really lock in moisture.⁣

Why a higher % is not 𝘢𝘭𝘸𝘢𝘺𝘴 better...
You see two products side by side that are nearly identical but with different concentrations of active ingredient - Which one is better? 
The higher % right?
Not necessarily!
Two great examples of this are vitamin c and niacinamide:
🌿Research suggests that vitamin C (as ascorbic acid) is most effective at concentrations between 8-20%. At concentrations higher than 20% it doesn't appear to provide any additional benefit but is more likely to cause irritation.
🌿All of the research into niacinamide has focussed on concentrations of 2-5%, yet a lot of niacinamide serums are 10%. That's not to say that there is an issue using higher concentrations of niacinamide if it works for you but there is no evidence to suggest that it has any additional benefit and it may be more likely to irritate your skin.
🌿Then you have ingredients that function differently at different concentrations. For example, urea acts as a keratolytic at concentrations above 10% which means it may cause irritation (although research suggests it's well-tolerated).
🌿Retinol is recommended to be used at a maximum concentration of 1%, although a 2016 EU safety assessment suggested it was safe up to 0.3% (their worry seemed to be overall vitamin A intake and they suggested that anything above 0.3% should be reclassified as a drug - I'm not sure if this came to fruition or not). In my search, I found a really interesting post by @skincarewithpeter about why retinol % labels are often misleading (in case you're wondering why you've seen products claiming to have a concentration above 1%) - it's a little beyond my scope of understanding so I won't try to explain it in case I get it completely wrong!

Back To Basics - How often should you use skincare Back To Basics - How often should you use skincare actives?
Most of these are based on how often active ingredients were used in research studies with the exception of retinol and acids (which were often used daily - one study even used a prescription retinoid TWICE a day but they were used under close medical supervision).
Formulation and concentration of the active ingredient will play a part - e.g. low concentration actives in a cream are less likely to cause irritation than high concentration serums
For example, one study used a cream containing glycolic acid (and other AHAs) twice a day and found it to be well-tolerated and effective at treating acne (Uriage Hyseac was the cream used if anyone is interested).

Best Acids For Acne-Prone Skin (Only A Rough Guide Best Acids For Acne-Prone Skin (Only A Rough Guide, YMMV).
🌿Salicylic Acid is oil-soluble which means it can penetrate your pores and your oil glands. It's probably the best acid for reducing oiliness which makes it great for oily skin types. However, it can be too drying for dry skin and too irritating for sensitive skin.
🌿Mandelic Acid is an underrated AHA that has larger molecules and penetrates your skin slower than other AHAs which makes it gentle enough for sensitive skin. It can also help control oiliness although to a lesser extent than saliclyic acid. AHAs also help hydrate your skin which makes mandelic acid a great choice for combination skin that can be both dry and oily.
🌿Glycolic Acid is the most effective AHA but, due to it's smaller molecules, it's also the most irritating. Because of its effectiveness at boosting collagen production and reducing pigmentation, glycolic acid is a great option for aging skin that is still experiencing breakouts. It's also a good option if you experience post-inflammatory hyperpigmentation (PIH)/ brown acne marks.
🌿Lactic Acid has larger molecules than glycolic acid so it's less irritating. It's also a component of your skin's natural moisturizing factors (NMFs) and is probably the most hydrating AHA which makes it a great choice for dry, acne-prone skin. It may also be useful if you experience post-inflammatory erythema (PIE)/ red acne marks as well as PIH.
🌿Azelaic acid is a dicarboxylic acid that is found in grains like wheat, barley, and rye and has a mildly exfoliating effect on your skin. It's very effective at preventing the growth of acne-causing bacteria. It's often used to treat rosacea, as well as acne, due to its anti-inflammatory effects and ability to reduce skin sensitivity.

One key difference between lactic acid vs glycolic One key difference between lactic acid vs glycolic acid is that they have differing molecular weights. Glycolic acid has a smaller molecular weight (72) than lactic acid (90) which means that it can penetrate your skin with more ease - including the deeper layer of your skin (your dermis).
Generally speaking, this means that glycolic acid tends to be more effective than lactic acid. However, the effectiveness of AHAs is also influenced by the pH and concentration (%) of the formula/product, as well as how long it’s applied to your skin for. 
Some research has found that lactic acid is equally as effective as glycolic acid when it comes to improving skin hydration, fine lines, and wrinkles but causes less skin irritation. Lactic acid peels were also better tolerated than glycolic acid peels while providing similar improvements in melasma. So, if you have sensitive skin, lactic acid would probably be the better option.
One clinical study compared lactic acid vs glycolic acid creams (both 8% concentration) and found that 71% of people using the lactic acid cream and 76% of people using the glycolic acid cream saw an overall improvement to their sun damaged skin - suggesting that both creams were equally effective. Both creams improved overall sun damage and skin sallowness but lactic acid also improved mottled pigmentation and skin roughness.
Other research found that there was higher patient satisfaction with lactic acid vs glycolic acid peels.
It’s important to note that, while studies directly comparing lactic acid vs glycolic acid seem to favour lactic acid, there’s generally more overall research behind glycolic acid than there is for lactic acid - in other words, glycolic acid is the more tried-and-tested ingredient.

There seem to be two main concerns when it comes t There seem to be two main concerns when it comes to combining vitamin C (as ascorbic acid) and niacinamide together:
🌿Niacinamide may increase the pH of ascorbic acid and therefore make it less effective
🌿Acidic ingredients, like ascorbic acid, may convert niacinamide to niacin (nicotinic acid)
𝗪𝗶𝗹𝗹 𝗡𝗶𝗮𝗰𝗶𝗻𝗮𝗺𝗶𝗱𝗲 𝗥𝗲𝗱𝘂𝗰𝗲 𝗧𝗵𝗲 𝗘𝗳𝗳𝗲𝗰𝘁𝗶𝘃𝗲𝗻𝗲𝘀𝘀 𝗼𝗳 𝗔𝘀𝗰𝗼𝗿𝗯𝗶𝗰 𝗔𝗰𝗶𝗱?
First things first, your skin’s natural surface pH is slightly acidic with a pH level anywhere between 4.7 - 6.0. Any skincare product you apply to your skin has to adjust to this pH and is usually formulated with this in mind.
When you hear people talk about differing pH levels in skincare, it’s usually a misunderstanding about how skin care product formulation works. For example, an ascorbic acid product will be more effective if the formula has a pH of 3.5 or less, NOT if your skin has a pH of 3.5 or less.
As niacinamide has a similar pH to your skin, it won’t make ascorbic acid any less effective than your own skin would.
The issue of pH differences only becomes a problem when formulating products that contain niacinamide and ascorbic acid together.
𝗪𝗶𝗹𝗹 𝗔𝘀𝗰𝗼𝗿𝗯𝗶𝗰 𝗔𝗰𝗶𝗱 𝗖𝗼𝗻𝘃𝗲𝗿𝘁 𝗡𝗶𝗮𝗰𝗶𝗻𝗮𝗺𝗶𝗱𝗲 𝗧𝗼 𝗡𝗶𝗮𝗰𝗶𝗻?
Niacin may be as effective as niacinamide, but it activates your skin's immune system (Langerhan cells) which leads to the release of substances (prostaglandins) that increase inflammation and blood flow to your skin.
This facial reddening is often referred to as ‘niacin flush’ and can cause an uncomfortable or tingling sensation.
Many people avoid layering niacinamide and glycolic acid for this reason. However, niacinamide is a very stable ingredient and it takes a very low pH, a very high heat, and a long time to convert niacinamide to niacin in laboratory experiments.

Is there a right way to layer your skincare? No Is there a right way to layer your skincare?
Not really.
As long as all your products can penetrate your skin, it doesn't really matter which way round you apply them (except for sunscreen which should always goes last in your AM routine)
Here's a few examples of skincare layering techniques:
🌿Thinnest to thickest - the best starting point and general rule of thumb.
🌿Buffering - something to consider if you have sensitive skin
🌿Sandwiching - an enhancement on buffering
🌿Short-contact therapy - for when your skin really struggles to tolerate irritating actives
