5 MD Dermoutlet Best Sellers – May 2026: What Customers Are Buying This Winter
By Dr Mathobela
Winter has officially arrived, and if your skin is suddenly feeling dry, tight, flaky, itchy or just generally unhappy, you’re definitely not alone.
Every month, we take a look at the products our customers are buying most on MD Dermoutlet. While every skin type is unique, these monthly best-seller reports provide valuable insight into the skincare concerns South Africans are focusing on throughout the year.
As temperatures dropped across the country during May, we noticed a clear shift in purchasing habits. Customers increasingly reached for products designed to support the skin barrier, combat dryness and maintain scalp health. At the same time, pigmentation-focused favourites continued to perform strongly, proving that concerns like melasma and uneven skin tone don’t disappear just because it’s winter.
So, what made it into the MD Dermoutlet Top 5 this month?

1. MD Cosmeceuticals Vitamin C & Glutathione Gel Serum
The Brightening Favourite That Refuses To Give Up Its Crown
For another month, this powerhouse serum remained our number-one bestseller.
And honestly? We’re not surprised.
Pigmentation, uneven skin tone and dull-looking skin remain some of the most common concerns we hear about. While many people think winter is all about treating dryness, it’s actually one of the best times to focus on brightening and pigmentation management.
With less intense sun exposure than during summer, winter creates an opportunity to support your skin-brightening goals while maintaining consistent sun protection.
Why customers love it:
- Helps brighten dull-looking skin
- Supports a more even skin tone
- Provides antioxidant protection
- Lightweight and easy to layer
- Suitable for most skin types
Winter Tip: If pigmentation has been bothering you, now is a great time to start working on it before summer returns.

2. SBR Repair Cream
The Winter Rescue Product Everyone Needed
If there was one product that truly stole the spotlight this month, it was SBR Repair Cream.
This moisturiser climbed from fifth place in April to become our second best-selling product in May.
Why? Because winter has a way of making your skin feel like it belongs to someone else.
One day your skin feels normal, and the next it’s tight, itchy and desperately asking for moisture.
That’s where barrier repair products come in.
SBR Repair Cream helps replenish moisture and support the skin barrier, making it a favourite among people dealing with dryness, sensitivity and eczema-prone skin.
Why customers love it:
- Deep hydration
- Supports barrier repair
- Suitable for sensitive skin
- Popular among eczema-prone individuals
- A winter skincare essential
If your moisturiser suddenly feels like it’s doing absolutely nothing this winter, your skin may be asking for something richer.
3. Vichy Dercos Purifying Oil Control Shampoo
Because Oily Scalps Don’t Take Winter Off
One of the biggest surprises this month was seeing this shampoo enter the top five.
Many people assume oily scalp concerns disappear during winter. Unfortunately, your scalp didn’t get that memo.
In fact, frequent hot showers can sometimes make things worse by stripping away natural oils and triggering rebound oil production.
The result? Hair that feels oily again much sooner than expected.
The good news is that the right shampoo can help restore balance without over-drying the scalp.
Why customers love it:
- Helps regulate excess oil
- Leaves hair feeling fresher for longer
- Gentle cleansing action
- Suitable for oily scalp types
- Helps keep hair cleaner between washes
A reminder we love sharing: your scalp is skin too. It deserves the same care and attention as the skin on your face.

4. MD Cosmeceuticals Polypodium Leucotomos Capsules
The Winter Favourite That Reminds Us Sun Protection Never Stops
One thing we notice every winter is that people become a little more relaxed about sun protection.
The weather is cooler.
The skies are cloudier.
And sunscreen quietly starts getting forgotten.
Unfortunately, UV rays don’t disappear during winter.
That’s one reason why Polypodium Leucotomos Capsules continue to perform so well. Many customers use them as part of a comprehensive photoprotection routine, particularly those managing concerns such as melasma and pigmentation.
Why customers love it:
- Supports photoprotection
- Popular among pigmentation patients
- Frequently used alongside sunscreen
- Often included in melasma management routines
Winter may be cold, but your sunscreen still deserves a place in your daily routine.

5. Rite Aid Fresh Cell Scalp Shampoo
Proof That Scalp Care Is Having A Moment
Another newcomer to this month’s top five is Rite Aid Fresh Cell Scalp Shampoo.
More customers are beginning to realise that healthy-looking hair starts with a healthy scalp.
Just as we cleanse, moisturise and protect the skin on our face, our scalp also benefits from consistent care.
The growing popularity of scalp-focused products shows that people are paying more attention to long-term hair wellness rather than waiting for problems to appear.
Why customers love it:
- Supports scalp hygiene
- Suitable for regular use
- Helps maintain a healthy scalp environment
- Popular among customers focused on hair wellness

What Changed Compared To April?
One of the biggest stories this month was the rise of SBR Repair Cream.
As winter conditions intensified, more customers sought products designed to replenish moisture and support the skin barrier. SBR Repair Cream climbed from fifth place in April to become the second best-selling product in May.
Scalp care also emerged as a growing trend, with both Vichy Dercos Purifying Oil Control Shampoo and Rite Aid Fresh Cell Scalp Shampoo entering the top five.
Meanwhile, pigmentation favourites such as MD Cosmeceuticals Vitamin C & Glutathione Gel Serum and MD Cosmeceuticals Polypodium Leucotomos Capsules continued to perform strongly, showing that pigmentation management remains a year-round priority.
