What did I bring back from the Daewoong / DNC Aesthetics DEEP Symposium?

The DEEP Symposium is the DAEWOONG / DNC AESTHETICS MEDICAL AESTHETIC EXPERT PROGRAM, run jointly by Daewoong Pharmaceutical and DNC Aesthetics. As the name says, it is an expert training programme for doctors who use the two companies’ aesthetic products, and in 2026 it was held for the third time. It is not a consumer event: it is where doctors and speakers who actually use the products share cases and treatment planning.

Rather than trying to fix the whole face with one product, the focus was on working out what is lacking in the order skin texture → firmness → contour, and then choosing products. Day one covered how to build REALLO into plans for skin concerns. Day two used cases to show how DCLASSY, REALLO and thread lifting can be divided up when a patient wants more improvement after energy-based device treatment. There was also a remote live demonstration.

The part I took the longest notes on was the idea of “understanding each product’s properties and judging how to apply it for each patient.” I could set the questions I always ask myself in the consulting room side by side with other doctors’ cases.

DCLASSY is a CaHA (calcium hydroxylapatite) collagen booster. It works in two stages: right after injection the gel creates volume, and once the gel is absorbed, collagen forms around the microspheres that remain.

• Depth and amount — because it cannot be reversed, we reconfirmed the rule of not injecting it shallow and not overcorrecting
• Planning by goal — set the goal first (lifting, contour or skin renewal), then choose areas and dilution (the manufacturer’s CAST-Code)
• Combinations — dividing roles, for example DCLASSY for volume and firmness, hADM for texture and density

I have set out its strengths and limits separately in DCLASSY CaHA: strengths and limits.

REALLO INJECT FINE is a particulate, freeze-dried acellular dermal matrix (hADM) made by CGBio. Rather than prompting the skin to make collagen, it directly supplies the material the skin is built from (extracellular matrix).

• Powder form — it is mixed with hydration fluid just before treatment, so the concentration can be adjusted to the area
• Dividing roles — it does not create volume, so we do not mix it with CaHA or fillers; we plan separate roles
• Duty to inform — we also covered that, because it is human tissue, patients must be told so before treatment

More detail is in REALLO INJECT FINE (hADM): its strengths.

• In consultation, I make the first step clearer: is your main concern skin texture, firmness or contour?
• I keep to the rule of placing DCLASSY in deeper layers, in divided amounts, using less at the start
• I set REALLO alongside Rituo and CellREDM, the other hADM products we use, and choose by area and skin thickness
• Rather than putting several products in at once, I split treatment into sessions, watch how you respond, and then decide the next step

Attending a symposium means I studied; it does not mean I can promise results. But being able to test the judgements I usually make alone in the consulting room against other doctors’ cases is, I think, worth something to my patients too.
