Ingredient Grades and the ABCDE Melanoma Guide
Evidence-graded skincare knowledge, not brand recommendations.
Ingredient Evidence Grades
- Grade A - Retinoids — Strongest evidence for anti-aging and acne; start low concentration to build tolerance.
- Grade A - Vitamin C — Antioxidant with solid evidence for brightening and photoaging protection when stable.
- Grade A - Niacinamide — Well-evidenced for barrier support, oil control, and mild pigmentation improvement.
- Grade B - AHA/BHA — Good evidence for exfoliation and texture; can irritate if overused or combined with retinoids.
- Grade F - Topical Collagen — Molecules too large to penetrate skin; marketing claim not supported by evidence.
The ABCDE Melanoma Signs
- Asymmetry — One half of a mole does not match the other half.
- Border — Edges are ragged, notched, or poorly defined rather than smooth.
- Color — Uneven color or multiple shades of brown, black, or red within one spot.
- Diameter — Larger than 6mm, about the size of a pencil eraser, though melanomas can be smaller.
- Evolving — Any change in size, shape, color, or symptoms like itching or bleeding warrants prompt evaluation.
Skin of Color Considerations
- Post-Inflammatory Hyperpigmentation — Dark marks left after acne or irritation, more common and slower to fade in melanin-rich skin.
- Keloid Risk — Raised, thickened scars occur more often in melanin-rich skin; caution with piercings and procedures.
- Gentler Actives — Slower introduction of retinoids and stronger acids reduces risk of irritation-triggered pigmentation.
Common Condition Basics
- Acne — Clogged pores, oil, and bacteria; ranges from mild comedones to severe cystic acne needing a dermatologist.
- Rosacea — Chronic facial redness and flushing, often triggered by heat, sun, or certain foods.
- Eczema — Itchy, inflamed skin linked to a compromised barrier and immune response, often flares cyclically.
- Psoriasis — An autoimmune condition causing thick, scaly plaques, distinct from eczema in cause and treatment.
