SkinCeuticals Glycolic 10 Renew Overnight: What is Free Acid Value?

SkinCeuticals Glycolic 10 Renew Overnight: What is Free Acid Value?

Acids are everywhere when it comes to skincare products. From Lactic to Hyaluronic, and Salicylic to Mandelic, or even the ever popular, Glycolic Acid. But did you know that not all Glycolic Acids are created equally?

Today, we're taking a closer look at SkinCeuticals Glycolic 10 Renew Overnight to discover more about glycolic acid, and how you can use it in your own skincare routine to help you achieve and maintain beautifully healthy, radiant skin.

What Is Glycolic Acid?

Glycolic 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

Protocol:
An 8-week, single-center, clinical study was conducted on 52 females, ages 35-64. Glycolic 10 Renew Overnight was used once nightly in conjunction with a sunscreen.

How To use SkinCeuticals Glycolic 10 Renew Overnight

For the best results, SkinCeuticals Glycolic 10 Renew Overnight should be introduced into your routine slowly. Start by applying a pea-sized amount to clean, dry skin on the face and neck every other night for the first week. As skin starts to build up resistance, you can start to apply more regularly, eventually working towards applying every night.Always use alongside a broad-spectrum sunscreen. We love SkinCeuticals Sheer Mineral UV Defense SPF 50 as it's lightweight with an ultra-sheer texture and is suitable for even the most sensitive skin.
