P.CALM Barrier Cycle Black Teca Serum 30ml

Fast-acting relief for irritated skin with Black Teca™

This is P.CALM's second-generation calming serum, upgraded based on feedback from 450,000 customers with sensitive skin. It contains 1% of the brand's proprietary Black Teca™ complex (asiaticoside, asiatic acid, madecassic acid, and black yeast ferment extract) to quickly care for skin sensitized by external stressors. It also features 3.4% of 9 billion probiotic ferment (Lactobacillus Ferment) to help restore a compromised skin barrier.

Clinically proven calming benefits

In a human application test, a single use showed 3.9 times improvement in calming irritated skin and 3.1 times improvement in repairing a damaged skin barrier. It also completed a low-irritation test on sensitive skin, receiving a non-irritating rating with an irritation index of 0.02.

Lightweight, fresh texture perfect for daily use

The serum absorbs quickly without any sticky residue, making it ideal for everyday calming care. It also includes supporting ingredients like niacinamide (tone evening), Ceramide NP (barrier strengthening), and phytosphingosine (skin protection), and is a dual-functional cosmetic for brightening and wrinkle improvement.

• Sensitive skin that reddens easily from external irritation
• Skin with a weakened barrier prone to recurring breakouts
• Anyone looking for a lightweight, fresh calming serum

After toner, before cream — in the serum step

After cleansing and toning, apply this serum before your moisturizer. The Black Teca complex and fermented probiotics need to absorb first to deliver their full calming and barrier-strengthening benefits. If you layer multiple essences or ampoules, apply this one earlier in your routine, following the lightest-to-richest texture rule.

Morning and evening use

The lightweight, fast-absorbing texture makes it easy to incorporate into both your AM and PM routines. On days when your skin feels especially reactive, apply an extra layer in the evening for intensive calming care. If using in the morning, always finish with sunscreen as your final step.

Dispense onto hands and press in gently

Dispense 2–3 drops onto your palm using the dropper and warm the serum slightly with your body heat. Spread a thin layer over your entire face, then press gently with your palms to help it absorb. For areas prone to sensitivity — like the cheeks or jawline — feel free to apply a second layer.

Routine pairings by skin concern

• Redness from irritation: After a gentle toner, allow this serum to fully absorb, then seal with a calming moisturizer.
• Weakened skin barrier: Pair with a ceramide cream to help reinforce barrier strength.
• Balancing teenage skin: After cleansing with a mild cleanser, use this serum on its own, then finish with a lightweight, low-oil hydrating cream.

Storage and precautions

Store in a cool place away from direct sunlight and use within 12 months of opening. If you experience redness, itching, swelling, or other unusual reactions during use, discontinue immediately and consult a dermatologist. Avoid applying to broken or wounded skin.
