Collagen Boosting Secret Sun Lotion

The KSECRET Collagen Boosting Secret Sun Lotion is a Korean sunscreen formulated with anti‑ageing and skin‑care actives in addition to broad‑spectrum UV protection. It carries SPF 50+ PA++++ and incorporates hydrolysed collagen (reportedly 560,000 ppm) and adenosine to help support skin elasticity and reduce appearance of fine lines. It is marketed as a “sun lotion” with a multi‑functional role: UV defence + skin barrier support + collagen‑boosting.

Features and Benefits

• Broad UV protection: SPF 50+ and PA++++ for strong UVA and UVB defence. 
• High collagen content: Contains hydrolysed collagen at ~560,000 ppm, aimed at supporting skin firmness and elasticity. 
• Anti‑wrinkle/firming support: Includes adenosine and peptides (e.g., acetyl‑hexapeptide‑8, copper tripeptide‑1) to help with visible signs of ageing. 
• Additional skin‑care actives: Includes niacinamide, hyaluronic acid variants, soluble collagen, glutathione, biotin, etc., which can support hydration, tone and skin barrier. 
• Chemical sunscreen format: Uses four modern UV filters (e.g., diethylamino hydroxybenzoyl hexyl benzoate, bis‑ethylhexyloxyphenol methoxyphenyl triazine) for effective protection. 
• Lightweight formulation: Described as a "lotion", suggesting it may be lighter and more easily absorbed than heavy sun creams.

Suitable Skin Types

• Normal to combination skin: It provides strong protection and care without being overly heavy, making it suitable for everyday use.
• Mature/ageing skin: Because of the collagen, adenosine and peptide content, it is a good match if you’re concerned with firmness and fine lines.
• Dry skin: The inclusion of many hydrating ingredients (various hyaluronates) means it may be suitable for dry skin — though as with all sunscreens you’ll still want a good moisturiser underneath.
• Oily/combination skin: While a “lotion” format may be lighter, you should assess how it sits on your skin surface; if you tend toward oily and prefer very matte finishes, you may wish to test it out.
• Sensitive skin: While many supportive ingredients are present, this is still a chemical sunscreen and includes fragrance (according to one listing) so a patch‑test is recommended.
