Aesthetic comparison
Chemical peels, laser or cryotherapy: which one for your dark spots?
Sun spots, melasma, age spots — every spot has its ideal treatment. Clinical comparison of the three approaches offered at Réhabital in Côte Saint-Luc, by our Dermalogica- and SharpLight-certified aestheticians.
Quick answer
Short answer: for diffuse spots and dull skin, choose Dermalogica chemical peels (series of 3-6). For isolated or darker sun spots, SharpLight IPL laser is faster and more targeted. For one very localized, pigmented spot, FreezPen cryotherapy is the fastest (1-2 sessions). For melasma, we combine peels + home care.

The clinical perspective
Dermalogica Pro chemical peels are the most versatile approach. They treat not only spots, but also dull skin, enlarged pores, uneven texture, and fine lines. At Réhabital, our Dermalogica-certified aestheticians adjust the concentration to your phototype and the season — gentler in summer, deeper in winter. The result is progressive: each session refines the complexion, and after 3 to 6 sessions the skin is visibly clearer, brighter and more even.
SharpLight Rapid DPC Pro laser is a medical IPL certified for all Fitzpatrick phototypes, I through VI. It emits pulsed light selectively absorbed by the melanin in spots, which rise to the surface and flake off in 5 to 10 days. It's the fastest option for dark, well-defined sun spots: 2 to 4 sessions are usually enough. Our SharpLight-certified medical technician follows a strict protocol to avoid any risk of post-inflammatory hyperpigmentation.
DermaSpark FreezPen uses a precise nitrous oxide jet at -89 °C. It's reserved for very localized lesions: a single pigmented spot, a seborrheic keratosis, a cherry angioma. In 5 to 10 seconds, the lesion is frozen, forms a crust, then detaches in 7 to 14 days. It's the fastest and least expensive option when a single lesion bothers you. We don't use it for overall complexion treatment.
Recommended combination at the clinic: for moderate melasma or a generally uneven complexion with a few darker isolated spots, we combine a series of 4 peels + 1 FreezPen session targeted on the most visible spot. This approach yields 30% better results than a single modality, while staying under $900 for the full protocol.
