Oily skin is often dehydrated skin. That sounds counterintuitive, but when the skin lacks water, it produces more oil to compensate. The answer isn't less hydration; it's the right kind.

  • The Signature Serum Light carries the same SOM1X® barrier-strengthening complex as our original Signature Serum, in a lighter, faster-absorbing formula that feels completely weightless on the skin.

  • Use it alone as your daily serum or layer it over any of our targeted Concentrates as the second step in the Dr Somji Protocol. 

  • Our Signature Serum Light has been trialled and tested in our Clinics, and developed specifically to work for post-procedure skin, to help soothe, balance and reduce redness.
  • Formulated by Dr Munir Somji, Cosmetic Surgeon and Co-Founder of the award-winning Dr MediSpa Clinics.

What is the difference between the Signature Serum and the Signature Serum Light?

Both contain the same SOM1X® barrier technology, Green Tangerine Exosomes and Probiotics. The Signature Serum has a richer texture and includes Ceramides and Encapsulated Multivitamins — ideal for normal, dry or mature skin. The Signature Serum Light has a lighter, faster-absorbing texture with added Niacinamide and Marine Prebiotics specifically targeted at oily, combination and blemish-prone skin.

My skin is oily — do I really need a serum?

Yes. Oily skin is frequently dehydrated at a cellular level — the excess oil is often the skin's compensatory response to lack of water. The Signature Serum Light provides the correct type of hydration (water-based, not oil-based) to address this directly, which over time actually helps regulate sebum production.

Can I use Signature Serum Light with the Anti-Blemish Concentrate?

Yes — this is the recommended combination for blemish-prone skin. Apply the Anti-Blemish Concentrate first to areas of congestion and active blemishes, then apply the Signature Serum Light over the full face. Together they form the Anti-Blemish Power Duo.

Will this work under makeup without causing breakouts?

Yes. Over 90% of trial participants confirmed skin felt smooth and rebalanced, and multiple customer reviews specifically note it works well under foundation. The formula is non-comedogenic and oil-free.

When should I apply this in my routine?

After cleansing and applying any Concentrate to affected areas, apply Signature Serum Light over the full face, neck and décolleté. In the morning, follow with Vitamin C Daily Defence SPF30. In the evening, follow with Night Recovery Cream if desired.

Is this suitable for sensitive skin?

Yes — it is dermatologically tested and marked suitable for sensitive skin. The Marine Prebiotics complex also actively calms redness and stressed skin, making it a good option for combination skin with areas of reactivity.

Apply directly to cleansed face, neck and décolleté once or twice daily. When using a Concentrate, apply the Concentrate first, then follow with Signature Serum Light directly over the top.

Great product. I have acne prone skin and this is very light and I don’t need much. It lasts a long time. It is gentle on my skin and helps me keep away break outs.

I have oily skin and the lighter texture allows my skin to feel hydrated, soothed, and more even-toned every day. I’ve noticed a lovely, natural glow without any heaviness or stickiness, and it’s been perfect for both morning and evening use.

I've got really oily skin, so I want to streamline my skincare and not layer product after product. This serum does just that, and leave my skin plump without being too oily!!

Due to my skin being really sensitive, we have found that retinol can sometimes irritate it. The light signature serum is so much kinder on my sensitive skin and I have definitely seen changes in my skin since adding this into my skin care routine.

Again Love this product and use it on clients when I’m working as it’s light consistency works well under make up and creates a wonderful skin base to work from.

I have been loving the original Signature Serum, but found in the summer my skin almost had too much of a glow! I started using this Light version instead, and it's been absolutely perfect for my skin, improving the texture, plumping and adding just the right amount of glow! I have swapped back to the original for Winter on some days, as my skin is drier, but I like to alternate between the two. Such effective products that have totally transformed my skin since I started using!
