thank you! i do not consider myself a “guru,” (i primarily experiment with one color cosmetics brand — my employer!), but i appreciate the compliment. matte is my typical go-to lip texture, so you’ve come to the right place for shade recommendations.
feel free to ask your question any day of the week, as long as you know it will only be answered on tuesdays! regarding your porcelain complexion, nars recently extended its range of shades in pure radiant tinted moisturizer to include terre neuve and groenland, the former of which ranks before alaska, previously the palest. if you’re looking for more coverage and/or spot treatment, add radiant creamy concealer in chantilly.
note: this response is not to suggest you should purchase the exact products shown above as i do realize they are of a higher price-point. rather, keep the tips themselves in mind. (i choose to promote nars out of respect for my job.)
