Rich PL Topic is a professional cosmetic skin treatment combining liquid polylactic acid with crosslinked hyaluronic acid in a ready-to-use 10ml vial.
It is designed to support skin hydration, improve the appearance of the complexion and provide an immediate plumping effect while helping improve the appearance of skin density and visible signs of ageing. Promoitalia describes it as the first ready-to-use cosmetic product containing liquid polylactic acid stabilised within a hyaluronic acid matrix — the HA matrix helps protect the polylactic acid polymer fractions, supporting their stability within the formulation and helping maintain their cosmetic activity over time. This pack contains 1 × 10ml vial, intended for professional cosmetic use according to Promoitalia protocols.
Rich PL Topic pairs liquid PLA with a stabilising HA matrix for hydration and skin-quality support:

Rich PL Topic is a professional cosmetic formulation developed to improve the visible quality and appearance of the skin, combining polylactic acid with crosslinked hyaluronic acid. It is supplied as a ready-to-use liquid solution, removing the need for powder reconstitution before use, and is positioned by Promoitalia as a treatment designed to support skin hydration, improve the appearance of ageing skin and provide an immediate plumping effect.
Polylactic acid is the key component within the formulation — Promoitalia describes 20mg of PLA stabilised at medium polymerisation, intended to support the appearance of improved skin structure and density, and states that polylactic acid can support the activity of fibroblasts involved in the production of collagen and elastin. This makes Rich PL Topic suited to cosmetic treatment programmes focused on loss of firmness, visible signs of ageing, fine lines, reduced skin density, and dull or tired-looking skin.
The formulation also contains hyaluronic acid at 10mg/ml, crosslinked with BDDE, forming the matrix that stabilises the liquid PLA. Hyaluronic acid naturally attracts and retains water, which within a cosmetic formulation can help support hydration, visible plumping, smoothness, the appearance of firmness and a fresher complexion. The combination is designed to provide immediate hydration and plumping while supporting longer-term improvement in the appearance of skin quality.
A key feature of Rich PL Topic is the use of a hyaluronic acid matrix to stabilise the polylactic acid polymers. Promoitalia explains that the crosslinked HA matrix protects the PLA polymer fractions from rapid hydrolytic degradation, allowing the formulation to maintain the cosmetic benefits of the PLA component over a longer period — providing both immediate cosmetic hydration and plumping, and progressive improvement in the appearance of skin quality and density.
One of the primary benefits of Rich PL Topic is deep skin hydration: the HA component attracts and retains water, helping dry or dehydrated skin appear smoother, plumper, more supple, more luminous, less tired and more even in texture. The immediate plumping effect — associated primarily with the water-binding properties of hyaluronic acid — may temporarily improve the appearance of fine lines, superficial wrinkles, dehydration lines, texture and reduced firmness. The product is also designed to support the appearance of improved dermal density (re-densification of the dermal matrix), making it suitable for programmes aimed at improving the appearance of skin laxity, loss of firmness, age-related skin changes, poor texture, reduced elasticity and overall skin quality. Results may vary according to skin condition, treatment protocol and individual response.
Promoitalia lists improvement of the overall complexion as a primary benefit — professional treatment may help skin appear brighter, healthier, more revitalised, smoother, more hydrated and more uniform, supporting overall skin quality rather than acting as a camouflage or covering product. Rich PL Topic may be incorporated into professional cosmetic programmes addressing visible signs of ageing including fine lines, wrinkles, loss of elasticity and firmness, dehydrated skin, dull complexion, reduced density and loss of vitality. The appropriate approach should be determined following professional assessment of the patient’s skin.
Rich PL Topic is supplied in a ready-to-use liquid format. Unlike traditional polylactic acid powder formulations, it does not require reconstitution before professional cosmetic use, providing a convenient treatment format for practitioners following the manufacturer’s protocol. The ready-to-use nature does not remove the need for appropriate professional preparation, hygiene and product handling.
Rich PL Topic is part of Promoitalia’s Topic Selection cosmetic range and should not be represented as an injectable medicine or dermal filler. It should be used according to the cosmetic application techniques and professional protocols provided by Promoitalia, and practitioners should avoid using the product via routes that are not supported by the manufacturer’s instructions.
Before treatment, practitioners should complete an appropriate skin consultation considering primary concerns, skin type and condition, sensitivity, current skincare, recent aesthetic treatments, history of irritation, relevant allergies, active skin conditions and patient expectations. Treatment should be postponed where the skin is unsuitable or compromised. Reasons to postpone or avoid treatment may include:
Rich PL Topic may be incorporated into professional cosmetic protocols according to Promoitalia guidance, with application techniques determined by the manufacturer’s protocol, practitioner training, skin condition, treatment goals and patient tolerance. It should not be combined with aggressive cosmetic procedures unless specifically supported by the protocol.
Before use, confirm the correct product, check the 10ml vial and expiry date, inspect the packaging and solution for damage or unexpected changes, complete an appropriate consultation, confirm the skin is suitable and review relevant skincare and treatment history. Do not use if the packaging appears damaged or the solution appears unexpectedly altered. Treatment should be performed using appropriate hygiene standards — hand hygiene, appropriate preparation of the treatment area, clean or sterile equipment where required, avoiding contamination, and following the manufacturer’s handling instructions.
Possible temporary responses following treatment may include redness, mild sensitivity, warmth, temporary tightness, mild dryness or transient irritation. The patient should be given appropriate aftercare advice, and severe or unexpected reactions should be assessed by an appropriately qualified professional.
Aftercare should follow the specific Promoitalia protocol and the technique used. General professional aftercare may include avoiding unnecessary skin irritation, using gentle skincare products, maintaining hydration, avoiding excessive heat where appropriate, using appropriate sun protection, avoiding aggressive exfoliating products until the skin settles, and following the practitioner’s recommended regimen. Patients should contact their practitioner if they develop an unexpected or persistent reaction.
Rich PL Topic is intended for professional cosmetic use. Practitioners should be familiar with the Promoitalia treatment protocol, skin assessment, patient suitability, appropriate application techniques, infection prevention, contraindications, aftercare and monitoring skin response, and should only use the product according to the manufacturer’s intended cosmetic protocol.
