Abstract
St. John’s wort (Hypericum perforatum) has been intensively investigated for its antidepressive activity, but dermatological applications also have a long tradition. Topical St. John’s wort preparations such as oils or tinctures are used for the treatment of minor wounds and burns, sunburns, abrasions, bruises, contusions, ulcers, myalgia, and many others. Pharmacological research supports the use in these fields. Of the constituents, naphthodianthrones (e.g., hypericin) and phloroglucinols (e.g., hyperforin) have interesting pharmacological profiles, including antioxidant, anti-inflammatory, anticancer, and antimicrobial activities. In addition, hyperforin stimulates growth and differentiation of keratinocytes, and hypericin is a photosensitizer which can be used for selective treatment of nonmelanoma skin cancer. However, clinical research in this field is still scarce. Recently, sporadic trials have been conducted in wound healing, atopic dermatitis, psoriasis, and herpes simplex infections, partly with purified single constituents and modern dermatological formulations. St. John’s wort also has a potential for use in medical skin care. Composition and stability of pharmaceutical formulations vary greatly depending on origin of the plant material, production method, lipophilicity of solvents, and storage conditions, and this must be regarded with respect to practical as well as scientific purposes.

Skincare Benefits of St. John’s Wort
The fresh flowers of St. John’s Wort are crushed to release reddish-purple colored oil. The oil readily infuses in oils, serums and moisturizers. Here are the most effective natural skincare benefits of St. John’s Wort:
1. Treats Eczema (or Atopic dermatitis)
The antibacterial properties of St. John’s Wort have been medically proven to ease itching and redness in people suffering from eczema. The anti-inflammatory fatty acids and hyperforin in the herb also promotes the growth of new skin cells.
2. Reduces Sunburn
St. John’s Wort deeply nourishes and heals sunburned skin, due to the calming ability of the herb which reduces swelling and redness after long periods of sun exposure.
However, note that St. John’s Wort can cause sensitivity towards direct sunlight. You should choose a St. John’s Wort infused organic broad spectrum sunscreen with the correct ratio of hypericin (3:5%)
3. Protects against harmful UV rays
Hypericin and Carotenoids in St. John’s Wort protect skin from harmful UV rays. In fact, Hypericin has been shown to act as a ‘photodynamic agent’ to prevent skin cancer. Hyperforin in St. John’s Wort stimulates growth and differentiation of keratonicytes (the most common type of skin cells) which slows down photoaging of the skin.
4. Soothes Rosacea & Psoriasis
Rosacea causes redness of the skin which may progress and become more intense over time. St. John’s Wort interacts with the affected skin cells and calms inflamed blood vessels underneath the skin.
Though St. John’s Wort isn’t directly effective in reducing psoriasis scaling, it can reduce the appearance of inflammation and red patches. St. John’s Wort can be added to a sensitive skin friendly serum, supplementing other nutritious and moisture enriching herbs to produce an anti-inflammatory effect.
5. Reduces Acne Inflammation
Hyperforin in St. John’s Wort inhibits the growth of acne causing bacteria by reducing the hyperactivity of T-cells. Since acne can also be related to stress, the herb balances and calms both the skin and the mind, which works synergistically to reduce acne inflammation.
If you’re looking for a Sensitive Skin Treatment that truly produces long-lasting results, look for a formula that contains 100% natural and calming ingredients. There should be absolutely no toxic elements in the ingredient list in order to promote naturally healthier skin.
