MAC on the ingredient apps

Two of MAC's best sellers, read on five public ingredient databases: every one got different verdicts from different databases.

SlipperSkin finding

Read on 21 and 23 October 2026, 2 of 2 MAC products got different clean-or-flagged verdicts from EWG Skin Deep, INCIdecoder, SkinSAFE and Skincarisma; their mean EWG hazard score was 3 and mean Skincarisma score 93.5.

Part of our study of how ingredient apps disagree, now 88 products from 48 brands. Every figure below links to the page it was read from.

How do the ingredient apps rate MAC?

They do not agree on any of them. EWG Skin Deep scores hazard from 1 to 10 (1 to 2 is its low band); INCIdecoder names the ingredients it rates "icky"; SkinSAFE rates freedom from common allergens (100 is its top); Skincarisma scores from EWG's ingredient ratings out of 100. 0 of 2 get SkinSAFE's top rating.

Which listings may be out of date?

Formulas change and databases keep the list they were given. Where one database's ingredient list differs from the others on a clear marker (parabens or fragrance), or EWG labels its listing with a formulation year, we show it here as a question, not a finding: a majority of published lists is evidence, not proof of the current formula.

MAC Prep + Prime Fix+: SkinSort omits fragrance (3 lists with / 2 without; SkinSort date n/a)
MAC Prep + Prime Fix+: Skincarisma omits fragrance (3 lists with / 2 without; Skincarisma date n/a)
