We know it can be confusing! which acid and/or retinol should you be using? how often? am or pm? what's it doing anyway...we know, that's why we are here to help you. this month's skglog is going to break through the minefield of information and give you the clarity you need to make the right product decisions - glow-on...and if you still have questions, just ask!


aha's - Alpha Hydroxy Acid

AHAs help exfoliate the dead layers of the skin on the outermost layer using a sugar-based acid. There are several different kinds of AHAs and they all do different things for different skin types. We have several products that can be safely used on a weekly basis to improve texture, acne, brightening, or skin tone. AHAs are also great on the body to reduce conditions like Keratosis pilaris on the arms and legs, sun damage, scars… the list goes on!


What do they do? They create collagen in the skin, making cells turn over faster and the skin healthier.


NB: Don’t use AHAs with retinol.


Glycolic Acid

a derivative from sugar cane glycolic acid is great for pigmentation, acne, and wrinkles. Used in moderation it can drastically improve skin texture and even lighten scarring. If you have never used it before then you will definitely have to build up some tolerance but after just a couple of weeks, you will notice the changes.


One of our favs with glycolic is our Unblemished face wash.

It is a probiotic glycolic cleanser. Great for both men and women.

Best used in the evenings! Also, the SGL exfoliating pads, are great for the face and body. Use 1x weekly only as You don’t want to overuse AHAs or combine them with other certain acids.


Lactic Acid

is present in dairy and fermented vegetables. Great for dry or sensitive skin. Helps lighten and brighten dark spots too.


Malic Acid

comes from apple acids, and It's what gives fruits a sour taste.

It exfoliates the dead layers dislodging pore impurities and smoothing the texture of the skin to reduce fine lines and wrinkles. Works great as a solo ingredient and is mostly found in serums and peels.


Citric Acid

which is present in citrus fruits; limes, lemons, grapefruit, and oranges. One of my favs because it helps brighten the skin's pigmentation. It has astringent properties and acts as a chemical exfoliant. Maybe not the best choice for sensitive skin types but it does pairs well with other AHAs. Holds a high concentration of antioxidants and helps maintain a good PH balance.


Mandelic Acid

contains a larger molecule derived from almond extracts. It can be used to increase exfoliation with other AHAs. The least common ingredient we use- it has its perks like improving pore size and texture.


Tartaric acid

comes from grapes. Not as common of an AHA to be in products but it does its job of helping improve skin texture and age management. Tartaric acid has become a common ingredient in skin care products due to its keratolytic and astringent properties. It moisturizes the skin, stimulates the metabolism, promotes healing and it also has an anti-aging effect.


Salicylic acid

this is the most common BHA. Well known to treat acne but also a great anti-aging ingredient when used properly. Derived from Willow Bark, it can penetrate deeper down into the dead skin cells for a deep clean. Epionce Purifying wash is great for acne on the face and body and has a 2% Salyatic for home use.
