SSL. SKIN JOURNAL 004 | THE SCIENCE OF SKINCARE
A thoughtful skincare routine doesn't necessarily require more products.
Yet one question continues to come up: if you already use a moisturiser, do you really need a facial oil?
The answer lies in understanding what each product does — and what your skin actually needs.
01 | Understanding Your Skin Barrier
The outermost layer of your skin, known as the stratum corneum, plays an important role in maintaining moisture balance and protecting against external irritants.
When skin feels dry, tight or uncomfortable, the answer isn't always to introduce another product.
Sometimes, reassessing your cleansing routine, moisturiser and active ingredients is the more considered approach.
Healthy-looking skin begins with thoughtful daily care.
02 | Face Oil and Moisturiser: What's the Difference?
Moisturisers come in a variety of formulations.
Many combine humectants, emollients and occlusive ingredients to help hydrate the skin, improve softness and minimise moisture loss.
Facial oils primarily contain oil-based components. Depending on their composition, they can provide emollient benefits and help reduce moisture loss to varying degrees.
Although both can contribute to skin comfort, they do not necessarily serve identical purposes.
For some people with dry skin, adding a few drops of facial oil after moisturiser may provide an additional sense of softness.
For others, particularly those with oily or acne-prone skin, a well-chosen moisturiser may be sufficient.
The most effective routine is not necessarily the one with the most steps.
03 | Why Botanical Fatty Acids Matter
Not all botanical oils are created equal.
Their characteristics vary according to their botanical origin, extraction method and fatty acid composition.
Linoleic acid, an omega-6 polyunsaturated fatty acid, is associated with the normal function of skin lipids.
A study published in PLOS ONE in 2020 examined the chemical composition of cacay oil and identified a high proportion of polyunsaturated fatty acids, including linoleic acid.
These findings provide valuable information about the ingredient itself.
However, identifying a beneficial component in an oil does not automatically establish the clinical performance of every finished skincare product containing it.
Scientific understanding begins with recognising this distinction.
04 | Discover Cacay Seed Oil
Derived from the seeds of the Caryodendron orinocense tree, cacay oil has its origins in South America.
Smiling Skin Lab. selects 100% Colombian cold-pressed cacay seed oil, with no added fragrance or additional skincare ingredients.
Naturally rich in linoleic acid and containing tocopherols — compounds associated with vitamin E — cacay seed oil offers a considered botanical addition to a minimalist skincare routine.
We believe a facial oil does not need to promise everything.
Its value begins with ingredient transparency, simplicity and a thoughtful approach to daily care.
05 | Building a Minimalist Skincare Ritual
A simple routine can be both practical and considered.
Morning Ritual
Gentle cleanse → Suitable moisturiser → Broad-spectrum SPF 30+ sunscreen.
Evening Ritual
Gentle cleanse → Moisturiser → Optional facial oil, according to your skin's needs.
Facial oil is an optional finishing step, not an essential requirement for every skin type.
If you use retinol or a prescription retinoid, follow the relevant product or medical guidance. Facial oil should not be considered a treatment for retinoid-related irritation.
If redness, stinging or persistent peeling develops, review potentially irritating products and seek dermatological advice when appropriate.
Patch-testing a new skincare product before regular use is also a sensible precaution.
LESS, BUT CONSIDERED.
Skincare shouldn't be about accumulating more.
It should be about understanding what belongs in your routine — and why.
At Smiling Skin Lab., we believe in returning to the essentials.
