Ingredient Spotlight: Glycolic Acid
What is Glycolic Acid?
/ɡlaɪˈkɒlɪk ˈæsɪd/ (gly-KOL-ik AS-id)
Imagine glycolic acid as your seasoned best friend in the realm of skincare—reliable, experienced, and always there when you need a glow-up. This alpha-hydroxy acid (AHA) isn't just a passing trend; it has solidified its place in advanced skin care for over three decades. Its magic lies in its molecular structure, effortlessly penetrating the skin to deliver a multitude of benefits for all skin types.
Glycolic acid isn't just your average ingredient; it's the powerhouse you turn to for that instant skin refresh. Derived from sugar cane, this exfoliating marvel boasts the smallest molecular size among AHAs, allowing it to penetrate deeply into the skin's layers. Here's where the real magic happens: it dissolves dead skin cells, unclogs pores, and stimulates collagen production—all without the harshness sometimes associated with other exfoliants.

Benefits of Glycolic Acid
Glycolic acid is your go-to companion that elevates your skin by:
Refining Texture: It smoothens and refines your skin's texture, unveiling a smoother and more radiant complexion.

Application Insights
To harness the full potential of glycolic acid, ease it into your regimen and allow your skin to acclimate. Follow product instructions diligently—remember, it’s not just about the acid concentration but finding the right formulation for your skin’s needs. Since glycolic acid can heighten sun sensitivity, if you want to use it during the day you will need to protect your skin with a high-quality mineral-based sunscreen SPF or opt for evening application. Don’t forget to follow up with moisturizer to bolster skin hydration. Embrace this skincare ally for a morning glow that sets the tone for your day!
Selecting a Glycolic Acid Product
When selecting a glycolic acid product, carefully consider the concentration with your skin care expert to minimize irritation and maximize the effects! Look for formulations that blend glycolic acid with other gentle acids to minimize potential irritation. If you’re new to glycolic acid, start with lower concentrations and gradually increase as your skin acclimates. Follow the product’s instructions meticulously, and always shield your freshly exfoliated skin with sunscreen during the day.
