The science behind great skin: a beginner's guide to functional skincare.
Skincare isn't just about looking good. Functional skincare is a science-backed approach focused on improving your skin's underlying health.
What functional skincare is
Rather than addressing surface concerns, functional skincare addresses the root causes of skin issues, combining research with well-chosen ingredients. Three principles hold it together: strengthening the skin barrier, reducing inflammation and oxidative stress, and supporting cellular repair and regeneration.
In practice that means ingredients chosen for what they do, not for a marketing claim: niacinamide because it reduces redness, peptides because they stimulate collagen.
The ingredients worth knowing
- Hyaluronic acid: hydration and plumping.
- Vitamin C: brightening and antioxidant protection.
- Retinol: cell turnover and fine line reduction.
- Ceramides: barrier repair and moisture retention.
A simple skincare routine for beginners
- Morning: cleanser, antioxidant serum, sunscreen.
- Evening: double cleanse, active treatment, moisturiser.
Give it six to eight weeks before judging the result. Consistency, not intensity, is what produces visible improvement. If you are not sure which actives suit you, a skin consultation will tell you where to start.
Sunscreen is the step most routines skip
Of everything in a routine, daily sunscreen does the most for pigmentation, early lines and uneven tone, and it is usually the first step people drop. Use a broad-spectrum SPF 30 or higher, SPF 50 if you spend time outdoors, about two finger-lengths for the face and neck, every morning. That includes days indoors near a window.
Choosing products for your skin type
- Oily or acne-prone skin: a gel cleanser, niacinamide, a light gel moisturiser, and salicylic acid a few nights a week.
- Dry skin: a cream cleanser, a ceramide moisturiser, and hyaluronic acid applied to damp skin.
- Sensitive skin: fewer products, fragrance-free, and one new product at a time after a patch test.
- Pigmentation-prone skin: vitamin C in the morning, sunscreen without fail, and a dermatologist's plan before trying strong lightening creams.
Common questions
Thinnest to thickest. In the morning: cleanser, serum, moisturiser and sunscreen last. At night: cleanser, a treatment such as retinol, then moisturiser. Give each active a minute to settle before the next layer.
Yes, just not usually at the same time. Vitamin C works well in the morning under sunscreen, and retinol at night because sunlight breaks it down. Using them apart also lowers the chance of irritation.
Six to eight weeks for most changes, and up to three months for retinol or pigmentation. If nothing has changed by then, the routine needs changing, not more products.
