The lipstick is likely to look patchy, emphasize the flaking texture, and apply unevenly, since this lesson specifically compares this situation to how “heavy foundation can emphasize dry, flaky facial skin” – matte and long-wear formulas specifically are noted as tending to look worse over unprepped, flaky lip texture.

Exfoliation removes the loose, flaking dry skin first, addressing the actual textural problem directly; applying lip balm alone (without first removing this loose, flaking skin) would provide hydration but wouldn’t remove the existing flaky texture itself, meaning the flaking could still show through or affect how color applies even after moisturizing, so removing the texture first (exfoliation) before hydrating (balm) addresses both aspects of the problem in the appropriate order.

The color might slip or not adhere properly, since this lesson specifically notes that “applying color immediately over a thick, unabsorbed layer of balm can cause the color to slip or not adhere properly”; allowing time for the balm to actually absorb before applying color would help avoid this specific adhesion problem.

These represent the same underlying principle (appropriate prep affects how color product applies and performs) applied to a different specific area of the face; just as facial skin prep addresses how foundation interacts with the skin’s actual condition (oily, dry, combination), lip prep addresses how lip color interacts with the lips’ actual condition (particularly dry, flaky texture), meaning this lesson extends an already-established principle from earlier in the course to this new, specific application area rather than introducing an entirely unrelated new concept.

This asymmetry should be specifically considered, not ignored; this lesson explicitly notes that “uneven or asymmetric lips… may benefit from careful, individualized lip liner application… to help balance this asymmetry, rather than assuming both sides of every client’s lips are naturally identical,” meaning this specific client’s noted asymmetry calls for deliberate, individualized attention rather than a default identical-application approach.

This reasoning has some validity, since this lesson’s specific concern (patchy, uneven application, emphasized flaking) is directly tied to dry, flaky lip texture; if a client’s lips are already naturally smooth and well-hydrated without this specific problem present, the urgency of the described prep steps may be genuinely reduced for this specific client, though a makeup artist might still reasonably choose some baseline hydration as a general good practice, even if the more intensive concern this lesson addresses (visible flaking causing patchy application) isn’t currently present for this particular client.

This lesson specifically notes that matte or long-wear formulas “tend to look patchy, emphasize the flaking, and apply unevenly” over unprepped, dry lips; sheer formulas, being lighter in coverage and often more moisturizing in their own formulation, may be less likely to visibly emphasize underlying dry texture in the same dramatic way heavier, more opaque matte formulas would, though this lesson doesn’t explicitly guarantee sheer formulas are entirely unaffected by lip condition, just that the specific problem described is most strongly associated with matte/long-wear formulas specifically.

Given the limited time, the artist might need to balance thoroughness against the time constraint – perhaps doing a quicker, gentler exfoliation and applying balm somewhat earlier in the overall makeup process (so it has more time to absorb while other areas of the face are being worked on) rather than saving lip prep for last, allowing some absorption time to pass naturally during the rest of the application process rather than requiring a dedicated separate waiting period that the time constraint might not otherwise accommodate.

This lesson’s specific focus is on lip shape observation and lip prep as foundational considerations, while this lesson explicitly defers the actual specific technique for addressing asymmetry (individualized lip liner application) to the following lesson, which will cover lip liner and application technique in more depth; this reflects a deliberate sequencing choice similar to other lessons in this course (like face shape analysis preceding contouring technique), where identifying a relevant characteristic is established first, with the specific technique for addressing it covered in a subsequent, more technique-focused lesson.

Observing lip shape characteristics (like asymmetry) before beginning prep or application allows this information to inform later technique decisions (as this lesson notes, connecting to the next lesson’s liner content) from the very start of the process, rather than only noticing a relevant characteristic partway through or after application has already begun; early observation allows the artist to plan their full approach (including how liner might specifically address any asymmetry) with this information already in hand, rather than needing to adjust or redo work after starting without this initial observation.

This specific problem (feathering/bleeding beyond the lip line) is different from the dry-texture/patchy-application concern this lesson specifically addresses through prep; this issue more directly relates to lip liner’s role in defining and containing the lip line (mentioned briefly in this lesson as a preview but covered in more depth in the next lesson on lip application technique), suggesting this specific concern would be better addressed by reviewing that upcoming lesson’s content on lip liner’s specific function, rather than being primarily a lip-prep-related issue.

While these address different specific concerns, both represent foundational, observational and preparatory steps that should logically happen before moving into the more involved lip color application techniques covered in the following lesson – similar to how face shape analysis (Part 2) and skin type analysis (Part 1) each served as foundational, diagnostic groundwork before their respective subsequent technique lessons; grouping lip prep (addressing texture/application quality) and lip shape observation (addressing symmetry, informing later liner decisions) together in this single foundational lesson establishes both pieces of necessary groundwork before the following lesson builds on this foundation with actual application technique.
