SkinCeuticals Glycolic 10 Renew Overnight: What is Free Acid Value?
Acids are everywhere in skincare. From Lactic to Hyaluronic, Salicylic to Mandelic or the ever popular, Glycolic Acid. But did you know that not all Glycolic Acids are created equally? We are taking a closer look at SkinCeuticals Glycolic 10 Renew Overnight, read on to find out moreGlycolic Acid is an alpha hydroxy acid (AHA) that exfoliates and renews the skin surface by sloughing away dead, dry skin cells to visibly soften and reduce the appearance of ageing.Whilst there are many products available containing Glycolic Acid, every now and then a true Glycolic hero comes along! But what makes SkinCeuticals Glycolic 10 Renew Overnight different?This miracle product features a winning combination of active ingredients including 10% glycolic free acid value, 2% Phytic acid to promote skin clarity and brightness and a trio of soothing botanicals and oils to replenish and support the skin barrier.
What is “Free Acid Value?We asked SkinCeuticals Training Manager & Expert, Linda Blahr, to explain more“The free acid value of 10% glycolic acid is the optimised concentration for daily use to shed and dissolve surface dead skin cells for brighter and more youthful looking skin.A lower concentration only provides minimal exfoliation, and does not deliver the full glycolic benefit, whilst a higher concentration used daily can cause skin irritation and sensitivity.Furthermore, the low pH level preserves the strength of the glycolic acid for optimal efficacy on skin “ with proven tolerability.Check out the results from an 8-week clinical study:
- 36% average improvement in radiance
- 37% average improvement in skin texture
- 19% average improvement in skin tone
