Vitamin B – What It Does and Why It’s a Hero Ingredient in Your Skincare Routine

When we talk about essential vitamins for skin health, Vitamin B doesn’t always get the spotlight — but it should. This group of water-soluble vitamins plays an important role in everything from hydration and barrier repair to oil regulation and calming inflammation . In other words, Vitamin B is a multitasking powerhouse and an unsung hero in any skin health routine.

The Vitamin B complex includes eight different types , and several of them offer powerful benefits when used topically. At The Treatment Centre, we often recommend B vitamins for skin conditions like acne, sensitivity, dehydration, and impaired barrier function .

Here’s a closer look at the most relevant types:

Key Benefits:

• Regulates oil production – helpful for acne-prone skin

• Reduces inflammation and redness

• Strengthens the skin barrier

• Improves hyperpigmentation and uneven tone

• Enhances hydration

Why We Love It: Niacinamide is incredibly versatile and well-tolerated — suitable for virtually all skin types. It’s often found in serums and moisturisers targeting sensitivity, breakouts, and ageing concerns.

Key Benefits:

• Deeply hydrates and attracts moisture

• Promotes skin healing

• Soothes irritated or sensitised skin

• Strengthens the skin’s lipid barrier

Why We Love It: Ideal for reactive, post-treatment, or dry skin, B5 acts like a drink of water for compromised skin — making it a go-to after procedures or during skin stress.

Key Benefits:

• Helps regulate hormonal breakouts

• Supports sebum control

• Reduces inflammation in oily, acne-prone skin

Why We Love It: Less common topically, but Vitamin B6 can be incredibly helpful when taken internally or as part of a broader acne management plan.

B vitamins don’t just benefit the skin when applied topically. They’re also crucial internally — supporting cellular energy , nervous system health , and hormonal balance . Deficiencies can show up as breakouts, dryness, or slow healing.

At The Treatment Centre, we may recommend consulting an integrative doctor to explore whether targeted internal support — such as B-complex supplementation — is appropriate, especially when skin conditions may be linked to hormonal or systemic imbalances.

• Acne-prone or oily skin

• Sensitive or reactive skin

• Post-treatment or barrier-impaired skin

• Ageing or dehydrated skin

• Uneven skin tone or pigmentation issues

Look for products that include B3 (niacinamide) in concentrations between 5–10% for maximum benefit. Pair with barrier-strengthening ingredients like ceramides or hyaluronic acid for added results.
