Pigmented Skin Types

The same cycling pattern applies, but prioritize A-New or A-New-B for pigmentation:

1-4. Pigmented Oily / Breakouts / Sensitive types

• Same as non-pigmented counterparts, but add 1 extra A-New-B if pigmentation is a concern

5-10. Pigmented Normal / Dry / Aging / Sensitive / Rosacea types

• Same as non-pigmented counterparts, but add 1 extra A-New-B where anti-aging + pigmentation is priority

• Retinol days remain gentle if sensitive

✅ Rules applied:

1. 7-day cycle for each skin type.

2. Strong retinol limited to tolerant, non-sensitive skin.

3. Gentle retinol for sensitive or dry skin.

4. B-Strong for antioxidants/anti-aging, B-Gentle for repair.

5. Pigmented types slightly prioritize retinol for brightening.
