Biome Barrier

Key Benefits

• Post- and probiotic-derived ferments.

• Peptides and barrier lipids.

• Supports microbiome balance.

• Extra soothing comfort layer.

Biome Barrier is a post- and probiotic plus peptide gel cream created as an add-on layer for moments when skin feels tight, dry, or overworked. The formula focuses on restoring balance after actives, environmental stress, travel, or long days, offering immediate comfort without overloading an existing routine.

It contains Lactococcus and Bifida ferments, which act as postbiotic and probiotic-derived lysates to help restore the skin barrier and support microbiome balance. With added Tripeptide-38, the formula supports collagen and key matrix proteins to refine texture and improve skin resilience. It also includes ceramide NP, aloe, and cucumber to replenish moisture, calm irritation, and reinforce the lipid barrier.

The formulation includes lactic acid to help maintain optimal skin pH and support gentle renewal, alongside vitamin E to provide antioxidant protection and support long-term barrier integrity. Designed around a “less is more” philosophy, Biome Barrier layers easily over actives to bring calm, softness, and a visibly more balanced complexion when skin needs extra support.

Dr. Liv Kraemer Skincare follows a structured, clinical approach that trains the skin through three clearly defined levels. LEVEL I acts as the foundation, focusing on gentle exfoliation, barrier support, and daily protection to restart cell turnover and prepare the skin for actives. LEVEL II builds on this base by introducing retinol, retinal, and bakuchiol in a controlled way to push cell renewal, strengthen collagen production, and address early to visible signs of ageing. LEVEL III delivers targeted personalisation, addressing specific concerns such as blemishes or redness through advanced topical formulas and internal support that reflect the skin–gut connection. Skin ageing slows cell turnover, weakens the skin barrier, and reduces its ability to recover from daily stress. Without a structured approach, active ingredients often overwhelm the skin or deliver inconsistent results. Progressing through these levels in the correct order allows the skin to adapt, strengthen, and respond more effectively over time, leading to improved texture, better tolerance, and healthier-looking skin in the long run.

Founded by dermatologist Dr. Liv Kraemer, this Swiss-made skincare line stems from over two decades of clinical experience in dermatology, stem cell research, and skin longevity. Her science-backed 3-Level Skin Longevity Method focuses on skin training, not perfection—supporting cell renewal, collagen production, and UV protection from the inside out. Each formula is dermatologist-developed, clean, and designed to work with your biology using key actives like niacinamide and prebiotics. Dr. Liv Skincare puts you back in control of your skin health—simplifying routines and helping you build stronger, clearer skin that lasts.

Biome Barrier is an add-on — not a daily necessity. You can integrate it into any level of your Dr. Liv Method when your skin needs extra comfort.

Morning: Apply a thin layer before your Day Shield if your skin feels dry or tight. (Note: if you’re prone to pimples or congestion, skip this step — no extra layer needed.)

Evening: Use after your Overnight Smoother or Turnover Optimizer whenever your skin feels uncomfortable or overtreated.
