Riboflavin is vitamin B2. It is a bright yellow vitamin, and it is a common part of B-complex supplements. Here we look at what riboflavin does in the body and how that relates to skin. We also cover how much is in Dermal Radiance, food sources and safety.

- Riboflavin is vitamin B2. The body turns it into two helper molecules that are needed for energy production and for the growth of cells [1].
- Regulators accept the link with normal skin. In Europe, labels may say that riboflavin contributes to the maintenance of normal skin [3].
- Riboflavin supports an antioxidant system. The enzyme that recycles glutathione, an antioxidant made by the body, needs riboflavin to work [2].
- Low riboflavin shows up in the skin and lips. The signs include skin disorders and cracked lips [1].
- Dermal Radiance contains 50 mg of riboflavin. That is 3,846% of the Daily Value [4].
What is riboflavin?
Riboflavin, also called vitamin B2, is a water-soluble vitamin. The body turns it into two coenzymes, called FMN and FAD. They play major roles in energy production, in the growth and function of cells, and in the way the body handles fats [1].
Adult women need 1.1 mg a day and adult men need 1.3 mg. In the United States, the average intake from food is 1.8 mg for women and 2.5 mg for men [1].
How might riboflavin work in skin?
Energy for cells
Skin cells, like all cells, need a steady supply of energy. The two coenzymes made from riboflavin take part in the reactions that release energy from carbohydrates, fats and proteins [1][2].
Antioxidant recycling
Glutathione is an antioxidant made by the body. After it is used, an enzyme called glutathione reductase recycles it, and this enzyme depends on riboflavin [2]. In Europe, labels may say that riboflavin contributes to the protection of cells from oxidative stress [3].
What deficiency tells us
When the body runs very low on riboflavin, the skin and mouth are among the places it shows. The signs include skin disorders, sores at the corners of the mouth, swollen and cracked lips, and hair loss [1].
What does the research show?
The research on riboflavin supplements and skin is still growing. The points below are the ones that trusted sources agree on.
| Source | What it says |
|---|---|
| European regulators [3] | Riboflavin contributes to the maintenance of normal skin, and to the protection of cells from oxidative stress |
| National Institutes of Health [1] | Riboflavin is needed for energy production and for the growth and function of cells. A lack of it leads to skin disorders, cracked lips and hair loss |
| Linus Pauling Institute [2] | The enzyme that recycles the antioxidant glutathione depends on riboflavin |
How much riboflavin is in Dermal Radiance?
| Source | Riboflavin a day | Notes |
|---|---|---|
| Dermal Radiance (2 capsules) | 50 mg | 3,846% of the Daily Value, from the label [4] |
| Adult daily need | 1.1 mg (women), 1.3 mg (men) | [1] |
| Average intake from food, US | 1.8 mg (women), 2.5 mg (men) | [1] |
| A typical multivitamin | 1.3 mg | [1] |
Dermal Radiance provides 50 mg of riboflavin. The body can absorb up to about 27 mg from one dose, and any excess leaves the body in the urine [1].
Food sources of riboflavin
Dairy foods, meat and fortified cereals are the main sources [1][2]:
- Beef liver, 3 ounces: 2.9 mg
- Fortified breakfast cereal, 1 serving: 1.3 mg
- Fortified instant oats, 1 cup: 1.1 mg
- Plain yogurt, 1 cup: 0.6 mg
- Milk, 1 cup: 0.5 mg
What the research does not show yet
- We found no human trial of riboflavin by mouth that measured skin in healthy adults.
- Riboflavin deficiency is extremely rare in the United States, so most people already meet their need from food [1].
- We found no study of riboflavin combined with the other Dermal Radiance ingredients.
Safety and interactions
Riboflavin has a good safety record. No upper limit has been set, and no harm has been reported from high intakes. This includes 400 mg a day taken for at least three months [1].
Riboflavin is not known to interact with medicines in a way that matters in practice [1].
- Bright yellow urine is normal when you take riboflavin. It is harmless [1][2].
- Take it with a meal, as the label directs [4].
- If you take prescription medicines, ask your doctor or pharmacist before you start a new supplement.
Riboflavin is one part of Dermal Radiance
Dermal Radiance is a daily two-capsule supplement with 20 vitamins, minerals and plant extracts. They were chosen to support healthy collagen, skin firmness and elasticity, and radiance. Riboflavin is one of them.
Dermal Radiance has not been clinically tested as a finished product. For this reason, we cannot say how its ingredients work together.
If you take Dermal Radiance, you are not relying on riboflavin alone. It is one of 20 ingredients in each serving. Every ingredient and amount is listed on the label [4].
A daily skin supplement with 20 ingredients
