As frustrating as it can be - baby eczema does not have a single, definitive cause. But rather, it can be caused by a combination of genetic predisposition and environmental factors.

For genetics, mutations in the filaggrin gene can lead to a decrease in filaggrin protein, which is a key protein in the outermost layer of the skin. This can result in a weakened skin barrier, more water loss, more dry & scaly skin, and a pH imbalance, leading to eczema.

Environmental factors can be wide-ranging - irritants like soaps & detergents, allergens like dust mites, pollen and pet dander, and environmental conditions like extreme heat, cold and dry or humid air -- can all contribute to eczema.

Currently there is no cure for eczema. However, various treatments and management strategies can help control symptoms and minimize flare-ups.

Many children can also "outgrow" their eczema as they grow older and has their skin barrier matures. But, actively managing eczema in the younger years is nonetheless critical to skin health.

Most people notice a difference in skin softness and comfort within the first few uses — especially if the skin was dry, rough, or irritated.

That said, barrier repair in eczema-prone skin takes time. For deeper benefits like:

• Reduced visible dryness or flaking
• Calmer, less reactive skin
• Stronger, more resilient skin barrier

…you can expect to see meaningful results within 14 days of consistent use.

Our hero ingredient in Soothe & Seal Ultra-Rich Cream is 5% provitamin B5. A study found that a 5% provitamin B5 ointment was as effective as a 1% hydrocortisone (steroid) ointment after 2 weeks, although the steroid worked more quickly after 1 week. You can read the study here. However, unlike a steroid, provitamin B5 can be used year-round, with a 70 year safety track record.

Adults, especially those with sensitive, eczema-prone skin, would absolutely benefit from Song Lab products.

While our products are designed with ingredients that are gentle for babies, they're also:

• Rich in clinically backed ingredients like ceramides, provitamin B5, and squalane
• Free from fragrance, essential oils, food-based allergens, and over 80 common irritants
• Designed to support the skin barrier, regardless of age

Many of our beta testers were adults, given they could articulate what they were feeling better than children or babies. They absolutely loved the long-lasting moisturizing and soothing nature of our products.

Song Lab products undergo rigorous testing that goes above and beyond industry standards:

• Industry standard for human repeated insult patch testing (HRIPT) is 50 people for assessing potential of a substance to cause allergic skin reactions or irritation. We go above and beyond and test on 200, including those with sensitive skin.
• We go beyond industry standards to ensure product safety and stability — including running accelerated stability testing at 2x the typical duration to validate shelf life
• We conduct Challenge testing (also known as PET testing) to ensure that our product is effectively guarded against bacteria, yeast and mold growth

It means we intentionally exclude ingredients known to trigger allergic contact dermatitis, based on the American Contact Dermatitis Society’s (ACDS) Core Allergen Series — a trusted list used by dermatologists to identify common skin allergens.

These allergens are often found in everyday skincare products and include:

• Fragrances and masking agents
• Preservatives like formaldehyde releasers and methylisothiazolinone (MI/MCI)
• Botanical extracts and essential oils
• Lanolin, propylene glycol, and other high-risk emollients

This is part of what makes our products ultra-hypoallergenic by design

Yes — all Song Lab products are formulated without food-based ingredients, which studies suggest may increase risk for development of food allergies and skin sensitization, especially in babies and young children.

This includes avoiding:

• Nut oils (e.g., almond oil, shea butter, peanut oil)
• Coconut oil
• Oats and oat extracts
• Soy, wheat, dairy and other food-derived proteins
• Honey, fruit enzyme and food-scented botanicals
  

Our decision is based on emerging research that shows early skin exposure to food ingredients — especially on compromised or eczema-prone skin — may increase the risk of developing food allergies.

Song Lab is deeply inspired by the science-first, skin-barrier-focused philosophy of Korean skincare.

Our founders grew up taking annual trips to Seoul, bringing empty suitcases to pack full of Korean skincare and make-up products.

Here’s how that influence shows up in our products:

• Barrier-first approach.
  Korean skincare emphasizes supporting the skin barrier rather than stripping or over-treating. Our formulas reflect that — gentle, hydrating, and repair-focused.
• Biocompatible, skin-native ingredients.
  We use ingredients like ceramides, panthenol (provitamin B5), squalane, and beta-glucan — all staples of Korean "ATO" products used for supporting sensitive skin barriers
• Preventative approaches.
  Unlike Western skincare, which often focuses on treating visible problems, Korean skincare emphasizes maintaining a healthy, resilient skin barrier over time to help prevent issues from escalating in the first place
  

Provitamin B5, also known as panthenol, is a deeply hydrating, skin-repairing ingredient that plays a key role in supporting the skin barrier.

When applied to the skin, panthenol converts to pantothenic acid — also known as vitamin B5, a compound that is naturally found in the skin and plays a key role in maintaining a healthy barrier.

Why it matters:

• Pantothenic acid is already part of your skin’s biology, which makes panthenol incredibly biocompatible and well-tolerated, even on sensitive or baby skin
• It supports skin hydrating by drawing water into skin and helping reduce transepidermal water loss (TEWL)
• It also has soothing and anti-inflammatory properties, making it ideal for calming irritation, dryness and redness
• We use 5% in Soothe & Seal ultra-rich cream, a level supported by clinical research to deeply hydrate, reduce visible irritation and strengthen & restore skin barrier.

Because it’s already native to the skin, provitamin B5 helps support what’s already there — gently, effectively, and safely.

Dermatologists love petrolatum for a reason - it is best-in-class at what it does. Studies have shown that a 5% concentration of petrolatum can reduce trans epidermal water loss (TEWL) by more than 98%, compared to 20-30% reduction with other commonly used occlusives.

We have looked at the research on safety of petrolatum and mineral oil - and when properly refined, studies have shown they are completely safe in skincare. A review of 13 studies showed that there's no evidence that mineral oils or petrolatum become percutaneously absorbed - and therefore, use in skincare do not present a health risk to the consumer. In fact, petrolatum and mineral oil are two of the least allergenic skincare ingredients - given their stable and inert nature.

To provide extra layers of peace of mind to our customers, we use European Pharmacopeia grade white petrolatum (lip care grade and food grade) and European Pharmacopeia grade mineral oil. European Pharmocopeia is often considered safer than USP petrolatum due to its stricter purity standards.

The Campaign for Safe Cosmetics acknowledges that there are no known safety risks to petrolatum when properly refined - and call out that consumers do not need to avoid products using white petrolatum.
