Skincare ingredients recommended by cosmetic dermatologists: A Delphi consensus study

Area of Science:

• Dermatology
• Cosmetic Science
• Evidence-Based Medicine

Background:

• Ambiguity exists regarding preferred topical cosmetic ingredients for common skin concerns.
• Expert dermatologists' recommendations are crucial for guiding patient treatment.
• A systematic approach is needed to identify consensus ingredients.

Purpose of the Study:

• To identify topical cosmetic ingredients frequently recommended by dermatologists for specific skin concerns.
• To establish expert consensus on the most effective ingredients for fine lines, wrinkles, acne, redness, dark spots, large pores, dry skin, and oily skin.

Main Methods:

• Literature review to compile an extensive list of cosmetic ingredients.
• Expert panel review to narrow down the list to the most salient ingredients.
• Two rounds of Delphi consensus surveys with a panel of 62 dermatologists from 43 centers.
• Comparative literature review to assess supporting evidence for consensus ingredients.

Main Results:

• An initial list of 318 ingredients was reduced to 83 by an expert panel.
• Consensus was achieved for 23 key ingredients, including azelaic acid, benzoyl peroxide, glycolic acid, mineral sunscreen, niacinamide, retinoids, salicylic acid, and vitamin C.
• The majority of consensus ingredients are supported by high-level evidence (Level 1b or 2b).

Conclusions:

• Expert cosmetic dermatologists have reached a consensus on the most useful topical ingredients for common dermatologic concerns.
• This consensus provides a valuable resource for both clinicians and patients seeking effective skincare solutions.
• The findings highlight the importance of evidence-based recommendations in cosmetic dermatology.
