What to expect
Week by week, honestly
1
Week 1–2Expect a little dryness or flaking. Use it every third night, not nightly, and let your skin catch up.
2
Week 4–6Texture smooths out and skin starts looking bouncier rather than tired.
3
Week 12Fine lines soften. Collagen work is a marathon — the people who see results are the ones who did not stop at week four.
Typical for this kind of formula. Individual results vary with skin type, consistency and sun exposure.
