Hello readers and happy Thursday!
Last week I posted on lactic acid and today I am continuing this short series with glycolic acid so read on to find out more on this AHA.
Who: Glycolic acid
What skin conditions can it help: Aging, fine lines, texture concerns, acne and hyperpigmentation
Where it comes from: Sugar cane or made synthetically
Why it’s important: It breaks down the bonds between cells that allow for easier exfoliation of the skin and is great for treating fine lines, smoothing skin texture and acne. It has the smallest molecular structure which makes it permeate faster and deeper but can cause more irritation and inflammation. *Not recommended for thin skin.
How it’s used: Glycolic acid can be found in skincare products (i.e. cleansers, toners, moisturizers, serums) and also in professional treatments like chemical peels. It also acts as a strong degreasing agent meaning it’s great for removing oil. *Like any other exfoliating agent, limit use to a few times per week, wear sunscreen and use caution when using ingredients containing retinol as this can irritate skin.
See you tomorrow,
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,
