Hi everyone! How was your weekend? My week is off to a great start. I was able to attend a special event at the International Dermal Institute headed by Jane Wurwand who is the founder of Dermalogica. Such an amazing and inspirational woman! Her motivational speech was beyond fantastic and she has a lovely sense of humor and heart. Also, I found out I won the giveaway hosted by Maiko from SkinConciergeMaiko! Yay! Check out her blog for other awesome reviews and tips. 🙂
Alright, enough about that. Let’s get right to the topic of today’s post which is alpha hydroxy acids or AHAs.
What are Alpha Hydroxy Acids?
Technically speaking, alpha hydroxy acids “are a group of water-soluble carboxylic acids that work to release the desmosomes that hold skin cells together.” Hmmm. I fear I lost you guys. 🙂 In plain English, they are naturally occurring mild acids used as chemical exfoliants that help shed off dead skin cells. They are hydrophilic (attracted to water) and are pH dependent meaning they require a lower pH to be effective.
Why are they Beneficial?
AHAs are highly coveted and present in many anti-aging products/treatments for the following reasons:
- Allows for easier exfoliation
- Increased cell turnover (hello glowing skin)
- Stimulate fibroblasts to produce collagen and elastin (something that decreases over time)
- Firm the skin
- Smooth and improve skin texture
- Reduce lines and pigmentation
- Leads to a more youthful appearance and feel
- Increase ceramides (hydration)
*Note: Overly and aggressively exfoliating the skin can result in sensitive itchy red skin.
What are the Different Types of Alpha Hydroxy Acids?
- Lactic acid– derived from milk
- Glycolic acid-derived from sugar
- Citric acid- derived from citrus fruits
- Tartaric acid- derived from grapes
- Mandelic acid- derived from bitter almonds
- Malic acid- derived from sour apples
*A special note on AHAs: Overly and aggressively exfoliating the skin, with or without AHAs can result in sensitive itchy red skin. Also, when using AHAs, you’re more sensitive to the sun and more prone to burning so sunscreen is crucial!
I hope you found this information helpful and as always, if you have any questions, feel free to ask me. 🙂
Have a good Tuesday,
Stephanie

I did not know there are so many different AHAs! Great post! 🙂
stephieestie says
Thank you Cos! The most common ones you hear about are usually glycolic and lactic but there are a few more, less commonly used ones. 🙂
janandjot says
I am with Cos, I was like whaaa that many?! Thanks for the informative post <3 xoxo Janet
stephieestie says
Thanks for reading Janet! I always fear a bit when I do posts like these because they are more scientific and technical but I try to break it down. 🙂 Glad it’s helpful and yes, there are a few more, less commonly talked about AHAs aside from lactic and glycolic acid.
janandjot says
You did a great job of breaking it down 🙂 Love learning more about the skin <3
stephieestie says
Yay! Good to know. Thank you 🙂
janandjot says
You’re welcome <3

Same here! This was very informative – I love that I learn some science reading this, in addition to pretty makeup things lol
stephieestie says
Thank you Brianna! I’m glad you enjoy it. Hope you’re feeling better. 🙂
Colleen says
Oh man, one summer I used an AHA ace gel/cream thing on my face and my entire jawline turned into flakes! It literally looked like I had a beard of flakes going on – so bad!! I’ve stayed away from them ever since but I know they’re really helpful for dull and dreary skin
stephieestie says
Oh no! Sorry to hear that. As strange as it may sound, sometimes these products will create that reaction before things get better. It could also be that maybe the gel/cream was too strong for you. Sometimes, you need to ease into the products and start at lower amounts until your skin gets used to it.
Colleen says
I think you’re right in both ways, because I was slathering it on every night when it should have been once a week. My skin can be randomly sensitive at times too, so who knows!
stephieestie says
Oh, yeah. That’s why it’s important to follow the directions because products with highly active ingredients like these can cause all the flaking. Overly using these products can cause sensitivity in the long run too. If you decide to use them in the future, start off small and see how your skin responds. 🙂
SkinConciergeMaiko says
I didn’t know about AHAs so much, very useful post as usual!
And thank you again, I look forward to hear how you think about the product 🙂
stephieestie says
You’re welcome! I can’t wait to receive the product. 🙂

AHA’s are a must for me since I’m 40 and have fine lines and wrinkles out the wazoo. I use the Ponds Rejuveenes (I know I probably spelled that wrong and I’m too lazy to go look it up) mainly as a night cream right now, but sometimes for daytime I’ll use a little around my eye area (where I need it the most really).
jassy says
Hello! I am so glad to find someone in my age group and love beauty too. Don’t get me wrong I love to read any age beauty blog but it is nice to find someone with aging skin.
TheMakeupCase17 says
I hear ya. Luckily I look younger than I am. Most think I’m in my mid-late 20s. I just have good genes cos my mom looked younger than she was too.
stephieestie says
Honestly Amy, I would have never guessed you are 40. You look great! How is the Ponds working for you? Just be sure to be diligent about your sunscreen and use an eye cream with SPF, especially if you are outside a lot and wear sunglasses. 🙂
TheMakeupCase17 says
Oh I do. And thanks.
jassy says
Great post! I just purchased a product with AHA.
stephieestie says
Thank you for stopping by! Make sure to wear sunscreen, use small amounts and see how your skin responds to it. I’m here if you have any questions (my email is located in the About section). 🙂 Also, I noticed the comment you had for Amy from The Makeup Case (she’s awesome by the way) and I think these posts I wrote awhile back might be useful to you. 🙂 https://stephieestie.wordpress.com/2014/06/03/whats-aging-you/ https://stephieestie.wordpress.com/2014/12/03/makeup-411-dont-let-powder-age-you/ https://stephieestie.wordpress.com/2014/11/19/makeup-411-how-to-prevent-cakey-foundation/
Jen says
Ah such a great post! I feel like a lot of people don’t know much about AHA, I only know because I have a dermatologist who explained this to me. It’s so important to use sunscreen if you’re using AHA on your face. It almost defeats the purpose of using AHA in the first place if you don’t wear sunscreen. A very important and informative post, great job, Stephanie! 🙂
stephieestie says
Sunscreen is crucial not matter what but when it comes to AHAs, BHAs. retinol, it becomes that much more important. You’re right, it will defeat the purpose because if you’re looking to reduce pigmentation and or wrinkles, guess what is part if the cause? The sun! Thank you Jen for your comments. It makes me feel good that you heard this from your dermatologist and compare it with my post, information wise. It’s also great that you actually listen to your dermatologist. You know how many people say yeah, yeah and then come back asking why they aren’t seeing results. Sigh.
Jen says
You welcome! You’re post is a well of info for folks who don’t go to a dermatologist. You need to follow the steps correctly not just using the creams. I don’t know why people just get lazy with the sunscreen.
stephieestie says
<3 That means a lot! Yes, following directions correctly are a must and failure to do so can result in some pretty mean consequences. What irks me with sunscreen is the excuses people have. They claim it's filled with chemicals when they have no clue what a chemical really is. I understand the whole natural thing but not everything natural is good just as not everything chemical is bad- hello water. Or the fact that they 'make' their own sunscreen using coconut oil and zinc oxide. Yikes! If a biochemist I know couldn't get the formula right the first couple of times, and mind you he has degrees in this, how do you expect to get the same effective results with a DIY version? And then I see all these people agreeing, I'm sorry but I just can't. 🙁
Jen says
Wow, people actually go off and make their own sunscreen? I can’t even imagine what that mixture will do to your skin. I’m actually highly allergic to zinc oxide so I stick with a titanium oxide based sunblock.
V says
Your posts are always so informative
stephieestie says
Thank you V! 🙂 I enjoy writing them and teaching things people may have seen but perhaps never really understood.

Wow autocorrect, I’d love to know what stepwise is?

stephieestie says
Haha, it’s okay. Happens to be all the time but is that even a word? Gotta wonder sometimes with autocorrect. 🙂
georginam says
I love this post!!!! I feel like I need AHAs for like….my neck and chest etc. (too much info?!!! sorry!) Just cause washing alone doesnt seem to cut through the oil and dead skin. Maybe that would be on my luxurious list!!!
stephieestie says
No, that’s okay. They can be beneficial for those areas. Just always make sure to follow up with SPF-super important! 🙂
internetheartsbeauty says
Thanks for sharing these tips! I’ve been thinking of adding AHA or BHA to my skincare somehow. 🙂
stephieestie says
You’re welcome! I’ll be posting on BHA as well.
