What actually causes stretch marks
Striae are dermal tears, not surface pigmentation. This guide explains the biology in 4 minutes.
Why creams alone never fade them
Topical actives stop at 0.1 mm. Stretch-mark damage lives at 2–5 mm. The depth gap is the whole story.
How red light reaches the dermis
Wavelength-by-wavelength explainer. Why 630/660 nm is the dermal red window and 850 nm is not.
Protocol guides
How long until I see change?
Most members report visible movement between week 8 and week 12. The full remodel takes 16 weeks.
Can I skip days?
One missed session is fine. Three or more missed in a row resets the cumulative-dose curve — read why.
Pregnancy, breastfeeding, hormonal shifts
When red light is OK, when it isn't, and what we tell members in each case.
Skin-specific deep dives
Postpartum stretch marks
Why the abdominal stretch zones respond differently than hips and thighs.
Adolescent growth striae
Why younger skin tends to fade faster — and why the protocol still takes 16 weeks.
Weight-change striae
What to expect if your skin has been through significant up/down cycles.
