Hydrating Watermelon B3 + B5 Serum

5% Niacinamide + Panthenol + Hyaluronic Acid for lightweight hydration and everyday barrier support.

This oil-free serum is designed for skin that feels dry, depleted or out of balance. It combines 5% Niacinamide (Vitamin B3), Pro-Vitamin B5 and Hyaluronic Acid with Watermelon, Kakadu Plum, Acai and Cranberry extracts to support hydration, skin-barrier function and a smoother, more even-looking complexion.

Why it works

  • 5% Niacinamide: Helps support barrier function and improve the appearance of uneven tone, visible pores and texture.
  • Panthenol (Vitamin B5): Helps soothe and condition dry, uncomfortable-feeling skin.
  • Hyaluronic Acid: Attracts water to the skin for a plumper, more hydrated feel.
  • Antioxidant-rich botanicals: Watermelon, Kakadu Plum, Acai and Cranberry complement the formula with plant-derived antioxidant support.
  • Oil-free texture: Absorbs easily and layers cleanly under moisturiser, facial oil and SPF.

Designed for

  • Dehydration and moisture loss
  • Uneven-looking tone and texture
  • Visible pores
  • Skin that needs lightweight barrier support

How to use

Apply 2–3 drops to freshly cleansed and toned skin. Press gently over the face and neck, then follow with moisturiser or facial oil. Use morning and/or evening.

Before & After

Omg it cleared up my face in only 12 days!

"I suffered from this mystery skin rash that was inflamed, itchy & painful for 11 months. I tried so many lotions & creams but zero change. Even a dermatologist could not pinpoint was it was, just gave me cortisone cream and sent me on my way (the before photos show me with a layer of cortisone on it just to stop the itching). I used Samson & Charlies the gift facial oil in the mornings and the famous 24k facial oil in the evenings underneath a plain neutral moisturiser and omg it cleared up my face in only 12 days!! The itchiness has greatly subsided and my face is nowhere as angry looking and looks normal. Whatever is in those bottles is magic. My skin is smooth and hydrated too which is a great bonus and the oil absorbs in easily. I'm even using the gift oil on my mild eczema which appears on my arms and it greatly hydrated it. I highly recommend those products for skin acting crazy and to hydrate it."

Store owner replied: That is outstanding! so glad to hear this. Thank you for making our day

I have been using this for a year. It's my go to every morning, and when my skin is feeling very dry. Leaves my skin plumped and hydrated. Smells delicious and has no hidden nasties. Reasonably priced, and one bottle lasts about 2 months. Will keep on using until they discontinue.

Customer photo review of Hydrating Watermelon B3+B5 Facial Serum

I've bought this serum twice now and I'll buy it again. It's so smooth and calming and smells delicious. It helps with my breakouts and reduces the little lines the years have drawn around my eyes and forehead. I love to use it under the hydrating oil and moisturiser both morning and night. So lovely.

I'm over the moon with this product! It makes my skin feel really soft and smooth, and it smells so good :) Definetly recommend getting the larger volume one though, as I haven't had mine long, and it's nearly all gone! Well, I guess that's just because I love using it.. Maybe too much... haha.

Customer photo review of Hydrating Watermelon B3+B5 Facial Serum

I have ultra sensitive skin and have spent thousands of dollars on different brands, lotions and potions to find skincare that is effective and doesn’t make my skin react. I took a last chance with Samson & Charlie and I’m so glad I did, my 37 year old sensitive, congested skin now has a range to care for it and I am now a loyal customer and will not be going anywhere else. Thank you!

I ordered the hydrating watermelon B3 + B5 serum & I'm obsessed! It smells absolutely divine & the texture is nice & lite on my skin.

Hydrating Watermelon B3+B5 Facial Serum

Have been using for a few months now and love the radiance it gives my skin. Not sure but think this one smells different to the original bottle I purchased. Cant compare smell as had run out before receiving new bottle

Hydrating Watermelon B3+B5 Facial Serum

I can honestly say, this hydration serum is divine and my face has never looked or felt better. I’ve been using for 3 weeks now daily and combine with the facial oil. A little goes a long way. I’m 57 with dry aging skin, and this serum is perfect.

Hydrating Watermelon B3+B5 Facial Serum

Wow wow wow!!! Superheroes for your skin!!! I have developed a mild case of rosacea & I have been using the dynamic duo for a week. My skin took to it like fish to water. The redness has subsided, my skin feels & looks so much better. I will definitely purchase again as well as other products.

Hydrating Watermelon B3+B5 Facial Serum

It feels so light and refreshing to apply. Smells lovely, I think my skin looks healthier after using this for a few weeks. Long lasting moisture. Not “oily” in any way, light enough for summer and packs enough moisture for winter months (so far).

Hydrating Watermelon B3+B5 Facial Serum

Such an effective product to refine and soothe winter skin. It reduces redness and has such a hydrating effect on my skin. Smells delice and comes in sustainable packaging. My second bottle, love this product.

Hydrating Watermelon B3+B5 Facial Serum

I've just started my 3rd bottle of this beautiful serum. Its part of my daily morning routine. It smells devine and it absorbs completely into my skin. Try it....you're skin will thank you for it.

Hydrating Watermelon B3+B5 Facial Serum

Perfect partner with the 24k Facial oil. I put this on after the oil. I just smear it over my face and let it absorb naturally. Which it does quickly. Smells great too. I would like to see some videos demonstrating the use of the products.
