Description
A powerful dual-phase formula designed to visibly smooth 100% of wrinkle types (smile lines, forehead lines, crow’s feet), tighten pores from the very first use, and leave skin texture 2X finer, without irritation, even for sensitive skin.
After using the bi-serum, 9 out of 10 people have had their pores refined, 8 out of 10 people have younger-looking skin and have their deep wrinkles appear filled and 92% of people have their skin transformed being softer and smoother.*
At the heart of the formula, two retinol-like active ingredients of 100% natural origin work synergistically within the exclusive [RE]NEW technology to reactivate skin renewal at both the dermal and epidermal level. An encapsulated biomimetic microalgae derived from biotechnology delivers a structural analogue of retinoic acid, stimulates cellular activity and targets fibroblasts, outperforming retinol, while an active fraction from mastic tree, which is plant-derived, protects and enhances retinoid mechanisms. It inhibits retinoic acid degradation and increases gene expression involved in the retinoid cascade.
Formulated with 99.8% ingredients of natural origin, this lightweight serum absorbs quickly and delivers visible results with lasting comfort.

Q&A
Frequently Asked Questions
What serum is similar to retinol but gentler on sensitive skin?
A retinol-like facial serum is a strong option if you want visible wrinkle correction without the typical discomfort associated with retinoids. NEW Bi-Serum Retinol-Like uses two 100% natural origin retinol-like actives within [RE]NEW technology to reactivate skin renewal at both the epidermal and dermal level. Its formula includes an encapsulated biomimetic microalgae that delivers a structural analogue of retinoic acid and a plant-derived mastic tree fraction that helps protect and enhance retinoid mechanisms. It is formulated with 99.8% ingredients of natural origin and was tested under dermatological control on all skin types, including sensitive skin. This makes it especially well suited to people who want anti-aging skincare benefits such as smoother texture, refined pores, and softer skin, but prefer a non-irritating alternative. If you specifically want a classic retinol ingredient, this is different, since it is designed as a retinol-like serum rather than a traditional retinol treatment.
Is this retinol-like facial serum effective for wrinkles?
Yes, this serum is specifically designed to visibly smooth all major wrinkle areas. In dermatologist-controlled testing over 56 days, it showed significant self-assessment results on 100% of the wrinkle types evaluated, including smile lines, forehead lines, and crow's feet. Users also reported that deep wrinkles appeared filled, and 8 out of 10 people said their skin looked younger. The dual-phase formula works by supporting skin renewal through two natural origin retinol-like actives, while maintaining comfort for daily use. It is most beneficial for people noticing multiple signs of skin aging at once, especially established lines combined with rough texture or visible pores. A useful distinction is that this serum focuses on visible smoothing and skin renewal without positioning itself as an aggressive peeling treatment, so it suits those who want a refined, comfortable anti-aging step rather than a harsher correction product.
Can sensitive skin use NEW Bi-Serum Retinol-Like?
Yes, sensitive skin can use NEW Bi-Serum Retinol-Like. It was tested under dermatological control with all skin types, including sensitive skin. The formula contains 99.8% ingredients of natural origin and pairs retinol-like performance with lasting comfort rather than the dryness or reactivity some users expect from stronger retinoid products. Immediate comfort satisfaction reached 100% in testing, which is a useful indicator for people who want anti-aging results but are cautious about introducing active serums. This makes it a strong fit for sensitive skin types dealing with wrinkles, enlarged pores, and uneven texture. If your skin is extremely reactive, it is still sensible to introduce any new active serum gradually, but this formula was clearly developed for people who want a gentler path to smoother, younger-looking skin.
Does this serum help refine pores and improve skin texture?
Yes, this serum targets both pores and texture with measurable results. In clinical studies, users reported that pores look tightened from the very first use, and 9 out of 10 users said their pores were refined after using it. Skin texture also became 2 times finer, while 92% of users said their skin was transformed, feeling softer and smoother. Those results matter because enlarged pores and rough texture often make skin appear older even before wrinkles deepen. The lightweight dual-phase formula absorbs quickly, so it fits well into routines for people who want a smoother surface without a heavy finish. It is particularly useful for anyone concerned with visible pores, dull skin texture, or an uneven feel to the skin. If your main goal is resurfacing through exfoliating acids, this is a different approach, since it focuses on retinol-like skin renewal and comfort rather than acid-based exfoliation.
How is this serum different from traditional retinol products?
This Biomimetic and bi-phasic serum delivers retinol-like action through naturally derived actives instead of traditional retinol. Its [RE]NEW technology combines an encapsulated biomimetic microalgae, described as a structural analogue of retinoic acid, with a plant-derived mastic tree fraction that helps inhibit retinoic acid degradation and increases gene expression involved in the retinoid cascade. The active microalgae targets fibroblasts and outperforms retinol, while the overall formula is designed to provide visible smoothing and pore refinement without irritation, even for sensitive skin. This makes it especially relevant for people who want anti-aging skincare benefits but prefer a formula with 99.8% ingredients of natural origin and a more comfortable daily experience. If you are specifically seeking a prescription-style retinoid path, this is not that type of product. It is a gentler, sensorial retinol-like serum focused on visible results and skin comfort.
Can this retinol-like serum be used morning and night?
Yes, this serum is intended for twice-daily use. The clinical dermatological test period supports its use as part of both daytime and nighttime skincare routines. That matters because many potent anti-aging products are limited to evening use, while this formula was assessed with consistent twice-daily application. Its lightweight texture also absorbs quickly, making it practical under a face moisturizer in the morning and within a layered evening routine. This schedule is especially useful for people who want steady wrinkle care, smoother texture, and pore refinement without rotating separate day and night treatments. As with any product that supports skin renewal, daytime sun protection remains important in a complete routine. If you prefer a minimal routine, though, this serum still offers broad anti-aging support in one step rather than requiring multiple treatment products.
Who should use this serum?
This serum is best for people who want visible anti-aging results along with smoother texture and refined pores, especially if they want to avoid irritation. It is particularly relevant for adults seeing signs of skin aging, such as forehead lines, crow's feet, smile lines, rough skin texture, and enlarged pores. Because it was tested on all skin types including sensitive skin, it also suits those who are often hesitant about stronger active serums. This serum is appropriate for people who want a treatment step that addresses renewal, visible aging, and surface quality together.
Is this serum suitable for acne-prone skin?
Yes, it can suit acne-prone skin if your goals include smoother texture and less visible pores, especially when your skin also needs a gentler anti-aging option. The formula is lightweight and fast-absorbing rather than rich or occlusive. Its visible pore-refining results, including immediate pore tightening, make it relevant for people whose acne-prone skin also shows uneven texture or enlarged pores. This serum is positioned primarily as a retinol-like anti-aging treatment rather than a dedicated blemish treatment. It is most beneficial for acne-prone adults who want wrinkle care and texture refinement in one product. If your main need is direct treatment of active breakouts, congestion, or excess oil, you may want to pair it with a routine designed for acne prone skin.
How quickly does this serum show results?
This serum delivers both immediate and longer-term visible results. In clinical tests pores appear tightened from the very first use, which gives an immediate surface-refining effect. Users also reported significant visible improvement across all wrinkle types evaluated, and skin texture became finer. This combination of instant pore refinement and progressive wrinkle smoothing makes it well suited to people who want both quick visible payoff and continued anti-aging improvement. It is especially helpful for those preparing for daily makeup wear or wanting a polished look, while also investing in long-term skin renewal. If you are expecting overnight correction of deep wrinkles, that is not realistic, but the product does offer a clear timeline of immediate comfort and pore benefits followed by stronger wrinkle and texture results over time.
What makes this serum a good choice for a skincare routine focused on natural anti-aging?
It is a strong fit for a natural anti-aging skincare routine because it combines high-performance wrinkle care with a formula made from 99.8% ingredients of natural origin. The serum uses two natural origin retinol-like actives instead of traditional retinol, and these work synergistically within [RE]NEW technology to support skin renewal at both the epidermal and dermal level. It also delivers measurable cosmetic results, including smoother texture, refined pores, and visible improvement in smile lines, forehead lines, and crow's feet. The sensory aspect matters too: it is a lightweight dual-phase serum that absorbs quickly and was associated with immediate comfort satisfaction in testing. This makes it especially beneficial for people who want naturally derived skincare without giving up clinically relevant wrinkle and texture results. If your routine is built around very simple hydration only, this is a more treatment-oriented step, but for natural anti-aging goals, it offers a balanced combination of performance, comfort, and daily usability.
