Sticks, lotions or gels: Choosing the right sunscreen for you

What SPF is right for you? Does a tinted sunscreen impact your skin differently and do you need to reapply sunscreens after every two hours? These are some of the questions we have before buying a sunscreen. With sunscreens available in sticks, lotions, gels and a variety of combinations, it is important to look for a sunscreen that goes with your skin type, your activity level and the level of protection you need. ‘NO MAJOR DIFFERENCE IN THE VARIOUS TYPES OF SUNSCREENS’Dr Ramanjit Singh, Visiting Consultant, Dermatology, Medanta, Gurgaon, explains, “Mineral sunscreens, also called physical sunscreens, use zinc oxide and titanium dioxide to sit on the skin’s surface, reflecting UV rays like a shield. They are gentle on sensitive skin and offer broad-spectrum protection. However, they can leave a white cast and feel thicker. Chemical sunscreens absorb UV rays and convert them into heat. They tend to be lighter and feel greasier but may irritate some skin types. Hybrid sunscreens combine both mineral and chemical filters for a mix of benefits and drawbacks.” While the active ingredients found in sunscreens are different, there is no significant difference in the efficacy of sticks, lotions, or other forms of sunscreen. “The variations primarily come from the inactive ingredients and the overall formulation. As long as they are broad-spectrum and SPF 30+, the differing forms offer equal quality of defence against UVA/UVB when properly applied,” says Dr DM Mahajan, Senior Consultant, Dermatology, Indraprastha Apollo Hospitals. TIP Regardless of skin type, it is essential to choose a broad-spectrum sunscreen with an SPF of 30 or higher and re-apply it every two hours when exposed to sunlight for adequate protection against harmful UV rays. Choosing the right sunscreen for your skin type- People with dry skin should go for sunscreens that contain ingredients like ceramides or hyaluronic acid to prevent further dryness - Those with oily skin may prefer lightweight, oil-free, and mattifying sunscreen formulations that won’t clog pores or leave a greasy residue - Individuals with normal skin can use most sunscreen types, but gel or fluid textures might be preferable for their lightweight and nongreasy feel — Dr DM Mahajan How to apply Apply generously: Most people don’t use enough sunscreen, which reduces its effectivenessReapply frequently: Sunscreen can wear off due to sweat, water, or rubbing, so re-apply every twothree hours and after swimming or sweatingCheck expiration dates: Sunscreens lose potency over time, so discard any that may have expired – Dr Seema Oberoi Lall, Consultant, Dermatology, CK Birla Hospital, Gurgaon‘For swimming, go for water-resistant sunscreen’ It is important to consider your activity level as well before choosing a sunscreen. “If you are swimming or engaging in physical activity causing sweating, choose a water-resistant sunscreen with SPF 30 or higher and re-apply every three hours. SPF refers to protection against UVB rays SPF 30 blocks 97%, while SPF 50 blocks 98%. Both offer good protection, apply sunscreen half an hour before exposure to the sun,” shares Dr Ramanjit Singh. Also, note that sunscreen should be used in addition to other sun-safe behaviours, such as seeking shade during peak hours and wearing protective clothing, hats, and sunglasses, share experts. "The quantity of sunscreen has to be measured in terms of the fingertip units or you can also use one teaspoon for your face and neck and two for your forearms and arms and re-application is important if you are outside and swimming," shares Dr Bhawuk Dhir, Consultant, Dermatology, PSRI Hospital. Textures of sunscreen Stick sunscreens tend to contain more waxes, oils, and thickening agents to give them their solid, semi-solid consistency. This allows them to glide on smoothly without being liquid Lotion sunscreens have a thinner, more spreadable texture from using fewer waxes/thickeners and more emollients like oils, silicones, and emulsifiers Other sunscreen forms like sprays use alcohol and propellants, while gels use thickening polymers instead of waxes — Dr DM Mahajan, Senior Consultant, Dermatology, Indraprastha Apollo Hospitals
