TSW occurs when the skin becomes dependent on topical steroids after prolonged use. When steroids are discontinued, the skin can react intensely, causing burning, redness, oozing, and severe itch that goes beyond the original condition. It is not a relapse of eczema. It is a withdrawal process that requires its own approach.
During TSW, the skin barrier is significantly compromised. Filaggrin levels are often depleted, the microbiome is disrupted, and the immune response is dysregulated. Conventional moisturizers and steroid creams are not the answer. The skin needs targeted support that helps it rebuild from the inside and out, without triggering further dependence or irritation.
This collection is built around a dual-action approach designed with TSW skin in mind.
Topical support focuses on rebuilding the skin barrier, restoring filaggrin production, rebalancing the microbiome, and calming visible irritation without steroid creams or harsh actives.
Internal nutritional support provides the building blocks the skin needs to repair itself from within, including targeted amino acids that support filaggrin production and long-term barrier resilience.
TSW looks different for everyone. This collection includes gentle, clinically tested options suitable for babies, children, and adults at any stage of the recovery process. Every product is fragrance-free, microbiome-friendly, and formulated to minimize disruption to sensitive, reactive skin.
All products are clinically tested, dermatologist reviewed, and free from the harsh ingredients that can set recovery back. Many carry the National Eczema Association Seal of Acceptance. All are certified vegan and cruelty-free.
Codex Labs is a unique blend of science and innovation that really works! It's my new go-to skincare line, both personally and for my acne patients.
I’ve always had red, inflamed, and bumpy skin. I have tried every product you can imagine, but the combination acne prone skin set from Codex has been the ONLY product to clear up my skin. My skin tone is even, I have no bumps at all, and even my pores look smaller! I’ve only been using it for 3 weeks, and my skin is already soft, smooth, and glowing. I really can’t recommend these products enough!
Codex Labs combines modern biotech and genetic science to create authentic skin care products focused specifically on the hydration of my skin while retaining moisture as well as soothing my sensitive skin.
My skin has never looked or felt better in my 50+ years, and I've used it ALL. I am currently undergoing chemotherapy and the Bia Superfood moisturizer and eye gel are both keeping my skin moisturized and soothed. To the point where I'm actually getting compliments on my skin during this treatment! Unheard of!
