Skin booster ingredients in Daegu: HA, PN, PDLLA and CaHA explained
Read the Korean original
Summary The various ingredients introduced under the name of skin booster are classified according to their ingredients and treatment goals.
Key information
HA, PN, PDLLA and CaHA are different materials. Skin booster is not a single ingredient or a shared regulatory indication: confirm the exact product, formulation, treatment area and goals studied.
Before your consultation

- PDLLA and CaHA materials
- Hydration, texture and volume goals
General information, not a personal diagnosis or treatment plan. Suitability, risks and recovery require an individual consultation.
HA and PN explained
HA stands for hyaluronic acid and PN stands for polynucleotide. If the names are different, the ingredients, formulation, and researched uses should also be examined separately. HA products also have different compositions depending on whether they are cross-linked or not and their physical properties, so it is best not to understand that all products are the same moisturizing treatment just by listening to the ingredient names.

PDLLA and CaHA materials
PDLLA means poly-D,L-lactic acid, while CaHA means calcium hydroxylapatite. Some products are used for skin quality or volume, but the approved indications and directions must be checked for each product. A general description of a material does not establish equal effects across all concentrations, formulations or body areas.

Hydration, texture and volume goals
Reducing dryness, smoothing skin texture and restoring volume to a hollow area are different outcomes. Define the goal before judging a product. Expecting one ingredient to improve pores, scars, elasticity and volume equally may go beyond the evidence.
Understanding the type of evidence
The PN literature review included studies that were small in size and had different methods. Scar studies using PDLLA and radiofrequency together must be differentiated from results from the products alone. When reading a combined study or a study on a specific treatment area, first check whether it is the same as the product/method suggested in the actual consultation.

Reversibility and adverse reactions
filler-dissolving enzymes considered for HA dermal filler cannot be applied in the same way to all other injectable materials. Even when nodules or inflammation occur, the evaluation varies depending on the material. Knowing the correct product name and keeping records before injection is important not only for choosing the next procedure but also for treating adverse reactions.

FAQ
Are HA and PN the same ingredient?
HA stands for hyaluronic acid and PN stands for polynucleotide. If the names are different, the ingredients, formulation, and researched uses should also be examined separately. HA products also have different compositions depending on whether they are cross-linked or not and their physical properties, so it is best not to understand that all products are the same moisturizing treatment just by listening to the ingredient names.
Are skin texture improvement and volume supplementation the same effect?
Reducing dryness, smoothing skin texture and restoring volume to a hollow area are different outcomes. Define the goal before judging a product. Expecting one ingredient to improve pores, scars, elasticity and volume equally may go beyond the evidence.
Can all skin boosters be dissolved with enzymes?
filler-dissolving enzymes considered for HA dermal filler cannot be applied in the same way to all other injectable materials. Even when nodules or inflammation occur, the evaluation varies depending on the material. Knowing the correct product name and keeping records before injection is important not only for choosing the next procedure but also for treating adverse reactions.
