"Deep-In Shot": one more ampoule name borrowing injection language for a topical delivery claim

Why "Deep-In Shot" fits an established naming pattern across K-beauty ampoules

This catalogue has covered several products using injection-adjacent naming ("booster injection" mask, "Retinol Shot") where the actual mechanism is topical, particle-size-based delivery rather than anything resembling an injection — "Deep-In Shot" continues that same pattern, describing a delivery aspiration rather than a literal procedure.

What "designed smaller than pores" is claiming, and how to think about it

Formulating spicules and PDRN at a small enough particle size to fit within pore openings is a genuine, physically sensible engineering goal for topical penetration — smaller particles have a better chance of entering pore openings than larger ones, though "smaller than pores" alone doesn't guarantee deep dermal penetration, since pores and the skin's deeper layers are different structures.

Why spicules and PDRN are paired here rather than either used alone

Spicules create physical micro-channels (a mechanical delivery-enhancing technology covered elsewhere in this catalogue), while PDRN contributes tissue-repair signalling — pairing a delivery-enhancing technology with a repair-signalling active is a logical combination, using the mechanical technology specifically to help the PDRN reach slightly deeper than it might unassisted.

Why "Pink Vitamin" is simply a marketing name for niacinamide, listed separately in the same formula

The product description lists "Pink Vitamin" and niacinamide as if distinct, when niacinamide (vitamin B3) is very likely what "Pink Vitamin" refers to — an example of a single ingredient given a friendlier consumer-facing nickname, appearing redundantly alongside its own chemical name in the same ingredient list.

What tranexamic acid adds to the brightening side of this formula

Tranexamic acid works through interrupting a UV-triggered inflammatory pathway linked to melanin production, a mechanism distinct from niacinamide's melanosome-transfer interference — combining the two addresses pigmentation through two different points in the pathway, independent of the "Deep-In Shot" delivery naming.
