Collection: Best Sellers

The DOS Best Sellers collection brings together our most-loved and most-repurchased skincare, from hydrating day and night creams to concentrated serums and gentle cleansers. Every product here has earned its place through customer results and independent recognition, which makes it the simplest starting point if you are new to DOS.

Our best sellers are chosen by our customers, not by our marketing team. These are the products that are reordered most often, reviewed most highly, and recommended most frequently after a Skin Test. Several have also won international beauty awards, so what you see here reflects both real customer results and outside recognition.

Start with the Skin Test. It reads five things — your skin type, your skin's tendency, the season, your age and your sensitivity level — and returns a personalised routine of no more than three products. If you would rather browse, most people begin with a cleanser, one targeted serum and a night cream, which is a complete DOS routine.

DOS formulas are made to show a visible difference within 10 days of consistent daily use. Concentrated botanical actives and our absorption technology carry ingredients past the surface into the deeper layers of the skin, where change actually happens. Longer-standing concerns such as dark spots take longer, and we would rather tell you that honestly.

Yes. DOS was created by our founder Chrysanthi for her own reactive, barrier-compromised skin, after years of finding nothing that worked. Every formula is clinically tested for safety, free from parabens, sulfates and PEGs, contains zero alcohol, and is cruelty-free. If your skin is highly reactive, the Skin Test will factor that in before recommending anything.

DOS is a family business with its own research and its own laboratory in Greece, so every formula is developed and made in small batches by the people who created it. We use Greek herbs from the Olympus region, using the whole herb rather than a single isolated extract, so the botanical actives work together. Every ingredient we use is published in full on our site.

Yes, and this is central to how DOS works. Skin behaves differently in summer heat than in winter cold, so the goal is to keep it in balance rather than to use one fixed routine all year. In summer, lighter serums and protection do most of the work. In winter, skin needs gentle exfoliation, deeper hydration and our strongest night treatments.
