At Dermapure Erin Mills, we offer Clear + Brilliant laser treatments, two powerful yet gentle options that target different skin needs:

💠 Perméa – works on the surface to brighten tone, fade pigmentation, and boost hydration.
💠 Clear + Brilliant – goes deeper to refine texture, smooth fine lines, and improve overall complexion.

How it works:
▪️Creates microscopic “channels” in the skin to trigger natural healing.
▪️Stimulates new collagen + cell turnover.
▪️Leaves skin smoother, clearer, and more radiant over time.

Minimally invasive, with minimal downtime these treatments fit perfectly into a busy lifestyle while still delivering long-lasting results. 🙌

As the air gets cooler and drier, your skin needs a different kind of care. September is the perfect time to refresh your routine and repair the damage left behind by summer.

Here’s what we recommend adding to your lineup this season:
✨ Hydrating treatments like Skin Boosters or Skinvive to restore deep hydration and plumpness
✨ Clear + Brilliant, Signature Peels, or medical-grade facials to resurface and brighten
✨ IPL and Photorejuvenation to fade pigmentation, redness, and sun damage
✨ Switch your skincare products to richer moisturizers and antioxidant serums (like Vitamin C) for extra protection

Think of fall as a reset button for your skin. 🍁 The perfect time to repair, refresh, and prepare for the colder months ahead.

▪️Reduces Inflammation – calms redness and soothes breakouts.
▪️Balances Oil Production – helps prevent future flare-ups by calming overactive oil glands.
▪️Improves Skin Clarity – creates a smoother, more even complexion over time.

The best part? IPL not only treats acne, but can also improve pigmentation, redness, and even unwanted hair.

Even oily or acne-prone skin needs hydration. When your skin is dehydrated, it can go into “overdrive,” producing more oil to compensate. That often leads to clogged pores, breakouts, and irritation.

The right moisturizer keeps your skin barrier balanced, prevents moisture loss, and supports your long-term skin health.

Pair it with a cleanser that respects your barrier and daily SPF, and you’re already covering the basics of great skin health.

We can help you build the perfect routine for your skin type! All you have to do is book your appointment.

When paired with in-clinic treatments, this combination supports your skin’s health and maximizes results!

Ask us about our recommended Vitamin C and SPF options at your next visit or book your 360° consultation to create your custom routine.
